Greenwich mean and apparent sidereal time
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 depends on the longitude of the locality. WebMean sidereal time accounts only for secular motion (precession). Apparent sidereal time includes secular and periodic contributions. [ thGMST , thGAST ] = greenwichSRT( …
