Dear All, I just realize that I don't understand the Altitude Correction Table 10� to 90� for the Sun on page A2 in the Nautical Almanac. Does anybody know whether the exact formula (algorithm) that generates this table has been published? I can't seem to reproduce it with the calculator formulas given in the Almanac itself. Nor is it consistent with the results I get when I correct the sun observation for refraction by means of the star table and then apply horizontal parallax and average SD according to season... What am I missing? Best regards Herbert Prinz (from 1368950/-4603950/4182550 ECEF) P.S. Speaking of the sun: Has anybody on the list observed it in the last few days? Quite remarkable.
