Guest guest Posted July 19, 2008 Report Share Posted July 19, 2008 Dear Bhattacharjya ji, The problem of ascertaining the value of Ayanamsa is now not a observational problem. Modern astronomy is now far advanced and can measure any arc accurately , once method of its determination is agreed to. We are all presently depending on data given by positional astronomical centres. Ayanamsa is a angular distance between two points namely 1. V.E.POINT , which is called first point of Aries in Tropical  ZODIAC. This point recedes in zodiac in the back ground of fixed stars at a mean rate of about 50.3 sec. per year. This is accepted and adopted by most of savants in India. 2 Initial point of sidereal zodiac which lies in between the nakshatra of Revti and ASVIN.There is no unanimity among Indian Astrologers as to which should be the reference Star ,based on which initial point of sidereal zodiac should be fixed. As such this becomes partially the problem created by astrologers themselves.  As I know , most of the astrologers in India are of the view that Star Citra should be reference star and initial point should be opposite to it. If this view is accepted , then the following becomes the mathematical definition of Ayanamsa  Value of Ayanamsa = Tropical longitude of Star Chitra - 180deg.  Tropical longitude of star Citra (Virginis) for any era can be calculated from the Fifth Fundamental Catalogue(TK5) AND IT IS CLAIMED THAT THE DIFFERENCE IN CALCULATED AND OBSERVED VALUES WILL BE LESS THAN 0 " .04.

Dear Goelji, What I meant was that even the ayanamsa could be found out through the physical observation.

Sidereal signs are linked with Nakshatras and that is why they are called Nir-Ayana signs. Regards,  G.K.GOEL Messenger blocked? Want to chat?
