HOW TO CALCULATE THE PLANETS’ POSITIONS 55
easier to the beginner, but once the logarithm of interval has been found the logarithmic method will be found to be easier, quicker and more exact, for the answers obtained by the two methods are not always quite identical, and particularly in the case of the Moon logarithms should be used.
Having found the distance traveled by the planet during the interval between the G. M. T. and the nearest noon, to find the place of the planet at the G. M. T. (which is the end and aim of our calculating), we must add this increment of correction to the planet’s longitude on the noon nearest to the G. M. T. day if the G. M. T. is P. M., for in that case the planet has traveled farther than shown by the ephemeris.
If, on the other hand, the G. M. T. is in the forenoon (A. M.) the planet has not yet reached the position indicated for noon in the ephemeris, hence it will be necessary to subtract the distance of travel for the interval—the increment of correction—from the planet’s longitude given in the ephemeris for the noon nearest to the G. M. T.
In the present case the G. M. T. is after noon (P. M.), 80 we add:
Deg.  Min.  
Longitude of the Sun on the noon nearest the G. M. T., Aug. 2nd, as per ephemeris

Leo  9  31 
Longitude of the Sun at G. M. T.

Leo  5 
This position will be entered in the horoscope.
