Astrological Air Movement Charts
n judging the prevalence and velocity of the wind for any period, not only
must the Air Movement Chart be considered, but als9o the Temperature
Chart for the season. If the Temperature Chart does not indicate wind for
the season, it takes an Air Movement Chart showing much activity to give
even a moderate amount of wind. Each of the Air Movement Charts indicates how
much, relative to the Temperature Chart for the season, will be present during the
period it governs. And it shows exclusively, without reference to any other chart, on
what dates such wind movements as take place will happen.
And, of course, before any intelligent predictions can be made as to wind from an Air
Movement Chart, there must be a thorough knowledge as to just how much wind
commonly may be expected at the given season. The chart is not absolute; it merely
indicates the variations from the normal air movements, and when they will occur.
The Air Movement Charts are erected, at the place where it is desired to determine
the air movements, for the exact moment the planet Mercury, either by direct motion
or by retrograde motion, enters each sign. The chart so erected governs the wind for
the period until Mercury, either by direct or by retrograde motion, enters another
sign.
The stay of Mercury in a sign is variable. It may be only sixteen days, or it may be
over two months. Like the wind, Mercury's movements are changeable. But
however short or however long Mercury stays in a sign, that period is governed by the
Air Movement Chart.
Unfortunately for ease in erecting Air Movement Charts, most ephemerides do not
give the time of day when Mercury enters each sign. Before 1941 none of them did,
but commencing that year the American Astrology Ephemeris has annually been
giving this data precisely for Eastern Standard Time. As this 5 hours west, the EGMT
may be found by adding 5 hours to the time thus given, and the Local Mean Time may
be found by adding the time difference the place is east of the 75th meridian, or
subtracting the time difference the place is west of the 75th meridian. If the American
Astrology Ephemeris is used, in calculating both the positions of the planets and the
Sidereal Time for which the chart is erected, the interval is 12h greater than when
using a noon ephemeris, for its positions are calculated for 0h, the commencement of
the civil day, which is the midnight preceding noon on that day.

But if the year is earlier than 1941, or an American Astrology Ephemeris is not at
hand, the time Mercury enters each sign must be calculated. The rule for finding the
time it thus enters a sign is given at the front of this lesson, and is illustrated by examples
in considering the charts to be studied in this lesson.
For wind during the period covered by each Air Movement Chart, no other charts
should be consulted as to the time when the winds will occur. Winds are indicated by
the aspects made by the planets, in their movement through the zodiac and by change
in declination, to the degree on the Ascendant of the Air Movement Chart covering
the period. Mild aspects from mild planets do not stir up heavy winds, but only mild
air movements. The more violent the planet and the more violent the aspect the more
violent will be the wind indicated, always, of course, subject to what the chart
indicates, and to the indications of the season Temperature Chart.
There is only one way to become sufficiently familiar with Air Movement Charts as
indicating winds at any particular place that reliable predictions can be made. That is
actually to observe each aspect as it forms to the Ascendant and the air movement
coincident with it. This should be done from day to day over considerable time.
Weather Station reports, such as now in many regions are given over the radio, will
assist in this. But I have found that with no wind blowing at 6:00 A.M., at the time the
wind movement is recorded in the Weather Maps used in these studies, that it may be
blowing a gale by 11:00 A.M., and quite subsided by sundown. Repeatedly, days on
which the Weather Map has thus recorded almost no air movement at the time the
observation was recorded for its use, I have observed much of the day to be gusty, or
even extremely windy.
What the average individual wants, is to know, not how much wind is blowing before
breakfast, but whether it will blow enough at any time during the day to
inconvenience him in some anticipated under-taking. I mention this not in criticism
of the Weather Map, which served its own purpose, but to indicate that in checking
what the wind was on a given day its use is very restricted. Also, that the proper
approach to understanding how to predict wind movements is carefully to watch the
aspects of the planets to the Ascendant of the Air Movement Charts, and to record, in
terms applicable to human undertakings, just what the wind did on such days.
Thus it may be recorded that there was a strong wind from the northwest all day, that
it was quiet in the morning but gusty in the afternoon, that it was blowing a gale
during the night, but quieted down by 10:00 A.M., that there was a warm zephyr, or
whatever the conditions were. These notes, together with the aspects to the
Ascendant which coincided with the recorded air movements, will form a sound
basis for predictions in the kind of terms that the ordinary person understands and can
use in his everyday planning.

To illustrate the method used, however, I will have recourse again to the Weather
Maps issued by the U. S. Department of Agriculture, Weather Bureau. These maps
up to July 7, 1932, as issued in California, give the velocity of the wind at certain
stations at 6:00 A.M., Pacific Standard Time. After July 7, due to economy imposed
upon the Weather Bureau, the velocity was not given. Some information, however,
can be gleaned from the Climatological Data for each month, and we can use it as far
as it goes.
Air Movement Chart
December 19, 1931
--The ephemeris shows that between midnight Dec. 19 and midnight Dec. 20, 1931,
Mercury backed into Sagittarius. At midnight Dec. 19 (daily motion between Dec. 19
and Dec. 20) Mercury is moving 1° 20'. At midnight Dec. 20 (daily motion between
Dec. 20 and Dec. 21) Mercury is moving 1° 22'. The increment during 24 hours is the
difference, which is 2'.
The increment at noon on Dec. 20 is ½ of this, or 1'. Between Dec. 19 noon and Dec.
20 noon Mercury moves 1° 20'. Adding the 1' gives the travel on Dec. 20 at noon as
1° 21'. At noon Dec. 20 Mercury is past the aspect (b) 14'. Between Dec.19 noon and
Dec. 20 noon as Mercury moves 80', to find the increment ½ way from noon we take
7/80 of the daily increment of 2', which is 0'. We thus use the noon travel of
Mercury, which is (a) 1° 21'.
Subtracting log. (a) 1.2499 from log. (b) 2.0122 gives .7623, which is the log, of (d)
4h 09m. Subtracting this from noon gives the Greenwich time as Dec. 20, 7:51 A.M.
Subtracting 7h 53m (difference in time at Los Angeles) from this gives the time for
erecting the chart as December 19, 1931, 11:58 P.M. LMT., Los Angeles. Chart No.
170, erected for this data, is given in Chapter 02.
Los Angeles and its suburbs extend from the ocean to the mountains, and the
Weather Bureau makes a separate wind velocity report from each edge of the region.
One daily report is from Los Angeles Harbor, on the ocean, and the other is at the
observatory on Mt. Wilson, about a mile in elevation, and plainly visible from Los
Angeles. Roughly, the two stations thus reporting are about 40 miles apart, Los
Angeles Harbor being visible from Mt. Wilson when the weather is clear.
While the wind in the metropolitan area of Los Angeles will almost always be of less
velocity than the average of the two observation points, the average of the wind
velocity at these two points is probably the best index we could have of the average
over the Los Angeles area, it being understood that these observations do not cover
the entire day, but are for 6:00 A.M. Pacific Standard Time. Therefore, in indicating
the effect of the wind, not for the whole day, but as it is recorded at 6:00 A.M., I shall
consider all the aspects formed to the Ascendant, and give the wind velocity as
reported on that day at both observation points.

This Air Movement Chart indicates the wind, modified by seasonal Temperature
Chart No. 165, given in Chapter 01, from Dec. 19, 1931, until Jan. 14, 1932.
This Air Movement Chart No. 170 has windy Mercury, active Mars, stormy Saturn
and moderating Venus in the fourth. Breezy Sagittarius is on the cusp of the fourth,
and its ruler, Jupiter, is in the calm sign Leo. This accounts for ½ of the influence of
the chart.
Windy Virgo is on the cusp of the first, and Mercury, its ruler, is in the windy sign
Capricorn. This accounts for ¼ of the influence of the chart.
Jupiter, ruling the sign Mercury is backing into, is in calm Leo. This accounts for1/8
of the influence of the chart.
Of the planets in angles, Pluto, Uranus, Mercury, Mars and Saturn tend toward wind,
while only Venus tends toward calm. This accounts for 1/8 of the influence of the
chart.
While there would be some calm days, the indications are that there would be more
wind than normal. This was borne out by Climatological Data.
In considering the aspects of the planets to the Ascendant of an Air Movement Chart
it should be borne in mind that, as a rule, violent aspects, such as oppositions and
squares, signify more wind than do harmonious aspects, such as trines and sextiles.
The Ascendant is occupied by 27 Virgo 52 which gives its declination as 00 S 5O.
Dec. 20, the Sun made the square to the Asc., but as it was Sunday there was no
record.
Dec. 21, the Moon came to the trine of the Asc., with wind registering 10 miles at the
Harbor and only 5 miles at Mt. Wilson.
Dec. 22, Mercury made the square to the Asc., but this aspect, possibly due to trine of
Moon to Asc., brought. only 5 miles at the Harbor and 4 miles velocity on Mt.
Wilson.
Dec. 24, the Moon came square the Asc. from the windy sign Gemini, and the wind
rose in velocity to 8 miles an hour at the Harbor and to 20 miles an hour on Mt.
Wilson.
Dec. 26, the Moon made the sextile to the Asc., and the wind at 6:00 A.M. was 8 miles
an hour at the Harbor and 15 miles an hour on Mt. Wilson.
Dec. 27, was Sunday, with no record.
Dec. 28, the Moon was semi-sextile the Asc. from the calm sign Leo, resulting in
wind velocity of 6 miles an hour at the Harbor and 15 miles an hour on Mt. Wilson.
Dec. 30, the Moon made the conjunction with the Asc., with a wind of only 5 miles an
hour both at the Harbor and on Mt. Wilson. This day the Moon was also parallel the
Asc.
background image
Jan. 2, 1932, when the Moon came to the semi-sextile of the Asc. from the windy sign
Libra, the wind velocity at both the Harbor and Mt. Wilson went up to 10 miles an
hour at 6:00 A.M.
Jan. 2, Venus from the moderate sign Aquarius made the sesqui-square of the Asc.,
and the wind registered only 3 miles at the Harbor, but was up to 45 miles an hour on
Mt. Wilson. The sesqui-square is not a harmonious aspect.
Jan. 6, the Moon was square the Asc. from the fairly active sign Sagittarius, and the
wind at the Harbor registered 8 miles an hour and on Mt. Wilson only 4 miles an hour.
Jan. 9, the Moon made the sesqui-square of the Asc., and the wind registered only 3
miles an hour at both stations.
Jan. 11, the inconjunct of the Moon from Aquarius, a sign usually giving moderate
movement, increased the velocity to 10 miles at the Harbor and to 12 miles on Mt.
Wilson.
Jan. 12, showed little wind at 6 A.M., but that day windy Mercury made the square of
the Asc., and on the 13th the Moon made the opposition of the Asc. from the windy
sign Capricorn, resulting in a wind velocity of 18 miles an hour at the Harbor, but
only 8 miles an hour on Mt. Wilson.
Jan. 14, Mars came to the trine of the Asc., and the wind continued with some
velocity, registering 10 miles at the Harbor and 13 miles on Mt. Wilson.
Air Movement Chart,
January 14, 1932
--The ephemeris shows that Mercury goes into Capricorn between midnight Dec. 13
and midnight Dec. 14. At midnight Dec. 13 (daily motion between Dec. 13 and Dec.
14) Mercury is moving 1° 08'. At midnight Dec. 14 (daily motion between Dec. 14
and Dec. 15) Mercury is moving 1° 11'. The increment during 24 hours is the
difference, or 3'.
The increment at noon on Jan. 14 is ½ of 3', or 1½ '. Adding the 1½ ' to the motion at
midnight Dec. 13, gives the travel on Jan. 14 at noon as 1° 9½ '. At noon Jan. 14 to
reach the aspect Mercury must move (b) 2'. Between Jan. 14 and Jan. 15 Mercury
moves 1° 11', or 71'. To find the increment ½ way from noon to the position 2' past
noon we take 1/71 of the daily increment of 3', or 0'. As the increment is a little more
than that at noon, we use the noon travel, but the larger even
' instead of the smaller.
This gives the travel (a) as 1° 10'.
Subtracting log. (a) 1.3 133 from log. (b) 2.8573 gives 1.5440, which is the log, of (d)
41m. Adding this to Greenwich noon gives the EGMT as Jan. 14, 12:41 p.m.
Subtracting the time difference from Los Angeles--7h 53m--gives the time for
erecting the chart at Los Angeles as Jan. 14, 1932, 4:48 A.M. LMT. Chart No. 171,
erected for this data, is given in Chapter 01.
background image
Windy Uranus and breezy Moon are in the fourth house. Breezy Aries is on the cusp
of the fourth, and its ruler, Mars, is in windy Capricorn. This accounts for ½ of the
influence of the chart.
Windy Mercury is in the first house. Breezy Sagittarius is on the cusp of the first, and
its ruler, Jupiter, is in the calm sign Leo. This accounts for ¼ of the influence of the
chart.
Saturn, ruler of the sign occupied by Mercury, is in windy Capricorn. This accounts
for 1/8 of the influence of the chart.
Of the planets in angles, Pluto and Uranus are windy and the Moon is breezy. This
accounts for 1/8 of the influence of the chart.
We must conclude from the above that the period covered by this chart will be windy.
Climatological Data bears this out, recording two storms; one from the 12th to the
15th, and the other from the 30th to the 31st. The first of these storms started under
chart No. 170 when, as mentioned, first Mercury came square to its Asc., and then
Mars came trine to its Asc., but carried on under chart No. 171, here considered.
"High winds occurred during the two stormy periods." "On the 29th several stations
in the mountain sections reported a blizzard." Mercury in Capricorn on that day was
both parallel the Asc. and semi-sextile the Asc. Capricorn favors blizzards.
On January 22 Jupiter backed to the one effective degree of orb of trine Asc., and
remained within orb until the new Air Movement Chart came in on Feb. 4. Strong
aspects to the Asc. from slow moving planets, as will be indicated in Chapter 07,
favor storms.
Jan. 15, the Moon came trine the Asc. from the fairly windy sign Aries, and the
velocity registered at the Harbor was 24 miles, and on Mt. Wilson it was 10 miles an
hour.
Jan. 16, the Moon moved into the still sign Taurus, and made the sesqui-square to the
Asc. The wind moderated some, showing only 6 miles at the Harbor and 10 miles on
Mt. Wilson.
Jan. 17, the Moon was inconjunct the Asc., but as it was Sunday there is no record.
Jan. 20, after being quite mild for a day or two, when Mercury came parallel the Asc.,
and the Moon made the opposition to the Asc. from the windy sign Gemini, the
velocity jumped to 16 miles at the Harbor and 30 miles on Mt. Wilson.
Jan. 23, again after having a low velocity for a day or two, under the influence of
active Mars semi-square the Asc., and Jupiter trine Asc., the velocity again went up;
this time to 20 miles at the Harbor and 35 miles on Mt. Wilson. The Moon on the
same day was inconjunct the Asc.
Jan. 25, the Sun, a still planet, made the semi-square to the Asc. from breezy
Aquarius. The velocity at the Harbor was 6 miles, and on Mt. Wilson only 5 miles an
hour.
background image
Jan. 27, the Moon came to the square of the Asc. from windy Virgo, and the velocity
increased somewhat, registering 8 miles an hour at the Harbor and 5 miles on Mt.
Wilson.
Jan. 28, windy Mercury came semi-sextile the Asc., Jupiter was in perfect trine with
the Asc., and the Moon was sextile the Asc. The wind increased to 12 miles an hour at
the Harbor, and to 40 miles an hour on Mt. Wilson.
Jan. 30, with Mercury closely parallel the Asc. since the 27th, and the Jupiter aspect
still close, the velocity at the Harbor was 8 miles an hour, and on Mt. Wilson 10 miles
an hour.
Feb. 2, the Moon came conjunction the Asc., in the rather active sign Sagittarius, and
the wind jumped to 16 miles at the Harbor. There was no record for that day on Mt.
Wilson.
Feb. 3, Venus in Pisces, a rather still sign, came to the rather violent aspect, square the
Asc. The result was 12 miles recorded at the Harbor, and 5 miles on Mt. Wilson. Had
the aspect been from a more active sign, even though Venus is not a violent planet,
but rather mild, the wind, no doubt, would have been higher.
Air Movement Chart,
February 4, 1932
--The ephemeris shows that between midnight Feb. 4 and midnight Feb. 5 Mercury
moves into Aquarius. At midnight Feb. 4 (daily motion between Feb. 4 and Feb. 5)
Mercury moves 1° 33'. At midnight Feb. 5 (daily motion between Feb. 5 and Feb. 6)
Mercury moves 1° 34'. The increment during 24 hours is the difference, which is 1'.
The increment at noon on Feb. 5 is ½ of this, or ½ '. The travel between noon Feb. 4
and noon Feb. 5 is 1°33'. Adding the ½ ' to this gives the travel on Feb. 5 at noon as 1°
33½ '. At noon Feb. 5 Mercury is (b) 37' past the required position. Between Feb. 4
and Feb. 5 Mercury moves 93'. To find the increment ½ way from noon we take
19/93 of the daily increment of 1', which is 0'. As the travel is slightly less than the 1°
33½ ' at noon on Feb. 5, we use (a) 1° 33' as its travel.
Subtracting log. (a) 1.1899 from log. (b) 1.5902 gives .4012, which is the log, of (d)
9h 33m. Subtracting the 9h 33m from noon gives the Greenwich time as Feb. 5, 2:27
A.M. From this subtract 7h 53m, the time difference of Los Angeles, and it gives the
time for which the chart should be erected as Feb. 4,1932, 6:34 P.M. LMT, Los
Angeles. Chart No. 172, erected for this data, is given in Chapter 02.
Scorpio, on the cusp of the fourth does not indicate wind unless the chart as a whole
does. Its ruler, Mars, is in breezy Aquarius, and its co-ruler, Pluto, is in the quiet sign
Cancer. This accounts for ½ of the influence of the chart.
Calm Neptune is in the first house. Calm Leo is on the cusp of the first, and the Sun,
its ruler, is in breezy Aquarius. This accounts for ¼ of the influence of the chart.
background image
Uranus, ruler of the sign occupied by Mercury, is in windy Aries. This accounts for
1/8 of the influence of the chart.
Of the planets in angles, both Neptune and Venus are calm. This accounts for 1/8 of
the influence of the chart.
We conclude from the above that while there may be a few blustery days, indicated
by Uranus in Aries, the period as a whole will have little wind. This is borne out by
the report in Climatological Data.
The chart has 28 Leo 41 on the Ascendant, which gives the declination of the Asc. as
11 N 56. The strongest indication of wind in the chart is Saturn within the one
effective degree of orb of inconjunct the Asc. As this aspect came closer, even though
an inconjunct, there was hail and sleet and some wind, registering highest two days
before the aspect was perfect. Saturn is the storm planet.
Feb. 7, the Moon came parallel and opposition the Asc., but there is no record for that
day as it was Sunday. The following day, Feb. 8, there was 10 miles an hour at the
Harbor, but no record for Mt. Wilson.
Feb. 9, the Moon came inconjunct the Asc., and Saturn was within the 1 degree of
effective orb of inconjunct the Asc. The wind registered 20 miles an hour at the
Harbor and 10 miles an hour on Mt. Wilson.
Feb. 10, the Moon was sesqui-square the Asc., and Saturn closer to perfect
inconjunct the Asc. The wind registered 12 miles an hour at the Harbor and 14 miles
on Mt. Wilson.
Feb. 11, Saturn made the perfect inconjunct to the Asc., and Venus made the
inconjunct to the Asc. The wind registered 8 miles at the Harbor and 15 miles on Mt.
Wilson.
Feb. 12, the Moon came trine the Asc., and the wind went down to 5 miles an hour
both at the Harbor and on Mt. Wilson.
Feb. 14, the Moon made the square of Asc., but as this was Sunday there was no
record. The Moon was in Taurus, and on the 15th the wind registered only 8 miles at
the Harbor and 4 miles on Mt. Wilson.
Feb. 17, the Moon made the sextile to the Asc., with a wind velocity of 8 miles at the
Harbor, and 4 miles on Mt. Wilson.
Feb. 18, the Sun made the opposition to the Asc., and the velocity at the Harbor
jumped to 12 miles an hour, but was still only 4 miles an hour on Mt. Wilson.
Feb. 19, the Moon came to the semi-sextile of the Asc., and kept the wind, with the
help of the Sun opposition Asc. still in orb, 10 miles an hour at the Harbor, and raised
it to 20 miles on Mt. Wilson.
Feb. 21 was Sunday, and the 22 was on a holiday, so there are no records for these two
days.

Air Movement Chart,
February 22, 1932
--The ephemeris shows that Mercury goes into Pisces between midnight Feb. 22,
and midnight Feb. 23, 1932. At midnight Feb. 22 (daily motion between Feb. 22 and
Feb. 23) Mercury is moving 1° 48'. At midnight Feb. 23 (daily motion between Feb.
23 and Feb. 24) Mercury is moving 1° 50'. The increment during the 24 hours is the
difference, which is 2'.
The increment at noon on Feb. 23 is ½ of this, or 1'. Adding the 1' to the travel of
Mercury at midnight of Feb. 22, gives its travel at noon of Feb. 23 as 1° 49'. Between
Feb. 22 and Feb. 23 Mercury moves 1° 08'. At noon Mercury is (b) 51' past the
required position. We want the increment for ½ this distance, or 26/108 of the daily
increment of 2', which gives 0'. Thus we use the noon motion of Mercury on Feb. 23,
which as above found is (a) 1° 49'.
Subtracting log. (a) 1.1209 from log. (b) 1.4508, gives .3299, which is the log, of (d)
11h 14m. Subtracting 11h 14m from noon gives the Greenwich time as Feb. 23,
12:46 A.M. From this subtracting the Los Angeles time difference of 7h 53m, gives
the time at Los Angeles as Feb. 22, 1932, 4:53 P.M. LMT. Chart No. 173, erected for
this data, is given at the front of this lesson.
Scorpio, ruler of the cusp of the fourth, gives little wind unless the chart as a whole
indicates it. One of its rulers, Mars, is in breezy Aquarius, and the other, Pluto, is in
calm Cancer. This accounts for ½ of the influence of the chart.
Breezy Moon and quiet Neptune are in the first. Quiet Leo is on the cusp of the first,
and its ruler, the Sun, is in calm Pisces. This accounts for ¼ of the influence of the
chart.
Neptune, ruler of the sign occupied by Mercury, is in windy Virgo. This accounts for
1/8 of the influence of the chart.
Of the 5 planets in angles, Sun and Neptune are calm, Mars and the Moon are breezy,
and Mercury is windy. This accounts for 1/8 of the influence of the chart.
The indications for the duration of this chart are that there will be some windy days,
but that the wind will not be violent, and that days of moderate wind movement will
be more common.
The Ascendant is occupied by 22 Leo 01, with a declination of 14 N 11.
Feb. 23, the Moon made the semi-sextile to the Asc. from windy Virgo. Only 2 miles
per hour was registered at the Harbor, but the velocity was 20 miles an hour on Mt.
Wilson.
Feb. 24, the Moon was semi-square the Asc. from windy Libra, and the wind was
blowing 12 miles an hour at the Harbor and 5 miles an hour on Mt. Wilson.
background image
Feb. 25, the Moon was sextile the Asc. from windy Libra, and the wind was blowing
11 miles an hour at the Harbor and 10 miles an hour on Mt. Wilson.
Feb. 27, the Moon came square the Asc. from the sometimes violent sign Scorpio,
and the wind at the Harbor registered 16 miles an hour, and on Mt. Wilson 5 miles an
hour.
Feb. 29, the Moon came trine the Asc. from the fairly windy sign Sagittarius, and the
wind registered at the Harbor 10 miles an hour, and on Mt. Wilson 8 miles an hour.
March 1, the Moon was sesqui-square the Asc., with only 5 miles registered at the
Harbor, and no wind on Mt. Wilson. Venus was also trine the Asc., but its influence is
generally to moderate.
March 4, the Moon came opposition the Asc., and the wind at the Harbor registered 4
miles and on Mt. Wilson 14 miles an hour.
March 5, Mercury made the inconjunct to the Asc., with only 3 miles an hour at the
Harbor, but 12 miles an hour on Mt. Wilson.
March 7, the Moon was inconjunct the Asc. from the calm sign Pisces, and the wind
at the Harbor was 6 miles an hour, and on Mt. Wilson 5 miles an hour.
March 8, the Moon was sesqui-square the Asc., and the wind at the Harbor registered
6 miles an hour, and on Mt. Wilson 5 miles an hour.
Air Movement Chart,
March 9, 1932
--The ephemeris shows that Mercury goes into Aries between midnight March 9 and
midnight March 10, 1932. At midnight March 8 (daily motion between March 8 and
March 9) Mercury is moving 1° 55'. At midnight March 9 (daily motion between
March 9 and March 10) Mercury is moving 1° 54'. The decrement during 24 hours is
the difference, which is 1'.
The decrement on March 9 at noon is ½ of this or ½ '. Adding the ½ ' to the travel of
Mercury at midnight of March 9, gives the travel at noon of March 9 as 1° 54½ '.
Between noon March 9 and noon March 10 Mercury moves 114'. At noon on March
9 Mercury needs to move (b) 39' to reach the required position. We want the
decrement for ½ this distance, or 20/114 of the daily decrement of 1', which gives 0'.
We thus use the nearest even ' to the noon travel, which, as the position is reached
after noon, is nearer (a) 1° 54'.
Subtracting log. (a) 1.1015 from log. (b) 1.5673 gives .4658, which is the log. Of (d)
8h 13m. Adding the 8h 13m to noon gives the Greenwich time as 8:13 P.M. From this
subtracting the 7h 53m time difference of Los Angeles, gives the time at Los Angeles
as March 9, 1932, 12:20 P.M. LMT. Chart No. 174, erected for this data, is given
at the front of this lesson.
background image
Windy Virgo is on the cusp of the fourth, and its ruler, Mercury, is in windy Aries.
This accounts for ½ of the influence of the chart.
Windy Pluto is in the first house, with breezy Cancer on the cusp of the first. Its ruler,
the Moon, is in windy Aries. This accounts for ¼ of the influence of the chart.
Mars, ruler of the sign occupied by Mercury, is in calm Pieces. This accounts for 1/8
of the influence of the chart.
Of the planets in angles, Pluto, Mercury and Uranus are windy, and the Moon is
breezy. This accounts for 1/8 of the influence of the chart.
The indications are that while during the period there will be many fairly calm days,
the windy influences are pronounced enough that quite high winds may be expected
at times. This is borne out by Climatological Data, which records several days of high
wind in April.
The Ascendant is occupied by 8 Cancer 21, with a declination of 23 N 11.
March 11, the Moon made the sextile to the Asc. from Taurus, a mild aspect and a
mild sign, and the wind at the Harbor recorded 6 miles an hour, and on Mt. Wilson 8
miles an hour.
March 12, the Moon was semi-square the Asc. from Taurus, and parallel the Asc. The
wind at the Harbor registered 5 miles an hour, and at Mt. Wilson 8 miles an hour.
March 13, when the Moon made the semi-sextile to the Asc. was Sunday and there is
no record.
March 14, Mercury made the square to the Asc., and the wind recorded at 6:00 A.M.
on the 15th was 10 miles an hour at the Harbor and 4 miles an hour at Mt. Wilson.
March 16, Venus came sextile the Asc. from Taurus, and the Moon came conjunction
the Asc. While the wind at the Harbor was only 3 miles an hour, on Mt. Wilson it was
35 miles an hour.
March 17, as a result of the two previous aspects, the wind at the Harbor was still 3
miles an hour, but had eased off on Mt. Wilson to 20 miles an hour.
March 18, the Moon was parallel Asc., but was also semi-sextile Asc. from the calm
sign Leo, and the wind on Mt. Wilson dropped to 4 miles an hour, and was only 4
miles an hour at the Harbor.
March 19, the Moon was semi-square the Asc. from the still sign Leo, and the wind
was only 2 miles an hour at the Harbor and 5 miles an hour on Mt. Wilson.
In considering the probable influence of the Air Movement Charts in producing wind
during the three months following March 20, 1932, the Temperature Chart
governing the season should also be scanned to perceive if the season as a whole will
be windy. This chart, No. 166, is given in Chapter 01.

It has windy Virgo on the fourth, and its ruler, Mercury, in windy Aries. Windy Pluto
is in the first. Calm Cancer is on the cusp of the first, but its ruler, the Moon, is in
windy Virgo. Mars, ruling the sign occupied by Mercury, is in calm Pisces. Of the
four planets in angles, Sun is calm, but Pluto, Mercury and Uranus are windy. Thus
for the season as a whole, considerable wind might be expected.
March 20, when the Moon made the sextile of the Asc., was Sunday, and there is no
record; but on the following day this aspect from windy Virgo resulted in a record of
only 4 miles an hour at the Harbor, but 25 miles an hour on Mt. Wilson.
March 22, when the Moon came square the Asc. from the windy sign Libra, the wind
at the Harbor was 5 miles an hour, but on Mt. Wilson it had increased to 35 miles an
hour.
The wind moderated on March 23, but March 24 the Moon came trine the Asc. from
the extreme sign Scorpio, and while it registered only 3 miles an hour at the Harbor, it
rose to 15 miles an hour on Mt. Wilson.

Asc., resulting in a recording on the 26th at the Harbor of 4 miles an hour, and 25
miles an hour on Mt. Wilson.
March 29, the Sun came square the Asc. and the Moon opposition the Asc., and the
wind registered 4 miles an hour at the Harbor and 10 miles an hour on Mt. Wilson.
March 31, the Moon made the inconjunct and the parallel to the Asc., and the velocity
at the Harbor was only 4 miles an hour, and on Mt. Wilson only 3 miles an hour.
April 1, the Moon made the weak aspect, sesqui-square the Asc., and the wind at the
Harbor continued at 4 miles an hour, and on Mt. Wilson at 3 miles an hour.
April 2, the Moon made the trine to the Asc. from the calm sign Pisces, and the wind
at the Harbor registered 4 miles an hour, and on Mt. Wilson 6 miles an hour.

wind at the Harbor registered 4 miles an hour, but on Mt. Wilson rose to 10 miles an
hour.
April 7, the Moon came sextile the Asc., and the wind registered at the Harbor 8 miles
an hour and on Mt. Wilson 5 miles an hour.
April 8, the Moon in Taurus made the semi-square the Asc., and as this is a slightly
violent aspect, the wind gained somewhat, registering 8 miles an hour at the Harbor,
and 20 miles an hour on Mt. Wilson.
April 10, the Moon came semi-sextile the Asc., but as it was Sunday there is no
record.
April 12, the Moon was semi-sextile the Asc., and there was very little wind.
April 13, Venus was semi-sextile the Asc., and this brought the wind up to 6 miles an
hour at the Harbor and to 10 miles an hour on Mt. Wilson.

increased to 8 miles an hour at the Harbor and to 10 miles an hour on Mt. Wilson.
April 17, the Moon came sextile the Asc. from windy Virgo, but it was Sunday and
there is no record. The following day, April 18, however, the wind registered 5 miles
an hour at the Harbor and 10 miles an hour on Mt. Wilson.

wind rose to 10 miles an hour both at the Harbor and on Mt. Wilson.
April 27, the Moon made the parallel and the in-conjunct aspect from the breezy sign
Aquarius, and the wind at the Harbor registered 8 miles an hour, while only 5 miles
an hour was registered at Mt. Wilson.

May 10, the Moon conjunction Asc. on the 9th took place after the 6:00 A.M.
recording, and influenced the wind on the 10th also. The record at the Harbor was 10
miles an hour, and on Mt. Wilson 17 miles an hour.

Air Movement Chart,
May 15, 1932
--The ephemeris shows that Mercury goes into Taurus between midnight May 15
and midnight May 16, 1932. At midnight May 14 (daily motion between May 14 and
May 15) Mercury is moving 1° 16'. At midnight May 15 (daily motion between May
15 and May 16) Mercury is moving 1° 19'. The increment is the difference, which is
3'.
The increment on May 15 at noon is ½ of this or 1 ½ ' Adding this to the travel at
midnight May 14, gives the travel at noon on May 15 as 1° 17½ '. Between May 15
and May 16 Mercury moves 79'. At noon May 15 Mercury lacks (b) 35' of the
required position. We want the increment ½ way from noon to this position, or 18/79
of the daily increment of 3', which is a little less than 1'. To the noon travel of 1° 17½ '
we add a little less than 1' and it gives us the nearest ' as (a) 1° 18'.
Subtracting log. (a) 1.2663 from log. (b) 1.6143 gives .3480, which is the log, of 10h
46m. Adding 10h 46m to noon gives the Greenwich time as 10:46 P.M. From this
subtracting the 7h 53m difference in time for Los Angeles gives the time at Los
Angeles as May 15, 1932, 2:53 P.M. LMT. Chart No. 175 erected for this data is
given in Chapter 05.
Windy Capricorn is on the cusp of the fourth. Its ruler, Saturn, is in the breezy sign
Aquarius, square windy Mercury. This accounts for ½ the influence of the chart.
Windy Libra is on the cusp of the first house, and its ruler, Venus, is in quiet Cancer.
This accounts for ¼ the influence of the chart.
Venus, ruler of the sign occupied by Mercury, is in quiet Cancer. This accounts for
1/8 of the influence of the chart.
Of the planets in angles, Venus moderates, but Pluto, Mars, Uranus and Saturn are
windy. This accounts for 1/8 of the influence of the chart.
The indications of the chart are that there would be calm days, followed by other days
in which there would be rather high winds. Climatological Data confirms these
indications.
The Asc. is occupied by 5 Libra 39, with a declination of 2 S 15.
