Guest guest Posted November 7, 2001 Report Share Posted November 7, 2001 Dear Sarajit, That is what I thought. But, by looking at the data sent by Sanjay, I figured out that he - intentionally or accidentally - set his sunrise preference to " Sun's tip is truly on the horizon " option. Remember that he and I have the same program. By changing the option, I could figure out what his setting was, in order to generate the sunrise time he gave in his mail. As for the arguments against " apparent " sunrise, see my previous mail. What will you do if Sun is not visible at all on a day? With the definition taken by Sanjay, lagna is about 16 arc-min behind Sun at sunrise. The exact difference depends on the distance between earth and Sun, which varies from season to season. JH computes it accurately. The only thing JH cannot compute accurately is the " apparent sunrise time " . It requires the refraction angle to be taken into consideration. This varies based on atmospheric pressure, temperature of atmosphere, humidity etc etc. This is actually not considered to be perfectly predictable.
