What I am trying to do : is see whether if we us elliptical
orbits instead of circular orbits, the velocity variations can
explain how the sun could be in Mesha, on a Chaitra Suklapaksha
Navami with the moon in the last pada of Punarvasu. (For a
discussion of the problem, please see : A Jatakam almost like
Sri Rama’s in 1956 and Casting Sri Rama’s Jataka Chakram!.. If
you like astrology, you can also see : Vimsottara Dasas for Sri
Rama, but it is not connected to the discussion below.) ie I am
trying to see whether on that day it is possible for the sun and
the moon to be separated by less than 93 degrees. The earth’s
velocity of orbit varies, with its position in the orbit. When
it is nearer the sun it goes faster. That means to someone on
the earth, it looks as if the sun is moving past the background
stars faster at this time. We normally take an average value of
360degrees/365.25days = 0.9856deg/day as the relative angular
velocity of the sun with respect to the earth. But you can see
from the Kepler’s Se
