It wouldn't print, however, so I copied the text into my mail program. The excerpt below should be interesting to western siderealists: " ...The ancient Indian astronomical text, Surya-Siddhanta lists a brilliant star CHITRA (Spica, alpha-virginis) as exactly on the 180 degree mark of the Sidereal zodiac. Chitra is therefore located at the exact opposite of the zero-point of the Sidereal zodiac. This is important since the Surya-Siddhanta gives no star for the exact zero degree mark. " The star Chitra becomes very significant when you understand that the ancient Hindus used shadow sticks and reflecting pools to measure the position of stars and planets. In order to observe solar movements especially, one would need reference points in the starry sky ***opposite the Sun*** for the obvious fact that no reference stars are visible during daylight. " Whenever Chitra is on the meridian of observation at local mean midnight it is known that the Sun is in the first degree of Sidereal Aries. Therefore the measurement of the Ayanamsha simply entails measuring the distance between the ECLIPTIC position of Chitra and the point of the Autumnal Equinox. For the year 1950 AD Chitra (Spica, alpha-virginis) was listed as 203d 09m l2s Ecliptic longitude. This is the same as 23d 09m l2s east of the Autumnal Equinox. Thus the Ayanamsha for 1950 AD is 23d 09m l2s. " ----------------------end of quote------------------- I had never thought of the night time observation of a star marking the opposite point to zero sidereal Aries! (The asterisks above are mine.) Donald Bradley originally accepted Spica as the sidereal fiducial star. He uses Spica in his SOLAR AND LUNAR RETURNS. I currently use the slightly offset Krishnamurti ayanamsa because of dasa/bhukti timing and solar ingress charts. Bradley was quite right that the Spica fiducial gave poor results for ingress charts. However, the Krishnamurti ayanamsa works extremely well, and (as I've pointed out on this site before) it's almost exactly a degree from the Fagan/Allen value (59 minutes plus a second or two depending on the year).
