WebNov 16, 2012 · I've written a couple scripts to determine solar time from hour angle. The first one uses ephem to compute right ascension and a formula from Meeus' Astronomical Algorithms to get Greenwich mean sidereal time, which can be converted to local mean sidereal with the longitude. WebGreenwich Apparent Sidereal Time (GAST) is the hour angle of the vernal equinox at the prime meridian at Greenwich, England. Local Sidereal Time at any locality differs from the Greenwich Sidereal Time value of the same moment, by an amount that is proportional to the longitude of the locality.
