HOW TO CALCULATE THE PLANETS’ POSITIONS 59


Venus will need logarithmic correction.

Deg. Min.
Longitude of Venus on the noon after G.M.T. (Aug. 3)
Virgo 6 21
Longitude of Venus on the noon before G.M.T. (Aug. 2)
Virgo 5 9
Venus’ motion on the G.M.T. day
1 12
Logarithm of Venus’ motion on G.M.T. day
1.3010
Logarithm of interval
1.0280
Logarithm of the Venus’ travel in interval
2.3290
Increment of correction (value of log, 2.3290 or the nearest thereto, in this case 2.3133) equal 0 degrees 7 min.
Deg. Min.
Venus’ longitude on the noon nearest G.M.T. (Aug. 2)
Virgo 5 9
Increment of correction
7
Venus’ long. to be entered in horoscope
Virgo 5 16

Mercury also has moved sufficiently to make it desirable to calculate his exact longitude at G. M. T. of birth by logarithms—

Deg. Min.
Longitude of Mercury on the noon after G.M.T.
Leo 9 22
Longitude of Mercury on the noon before G.M.T.
Leo 7 17
Mercury’s motion on the G.M.T. day
2 5
Logarithm of Mercury’s motion on G.M.T. day
1.0614
Logarithm of interval
1.0280
Logarithm of the Venus’ travel in interval
2.0894
colspan="4"
Value of log, 2.0894, or increment of correction, 0 degrees 12 minutes.
