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. WebJan 29, 2015 · Since the computation of Greenwich sidereal time is based on the UT1 time scale as is solar timebased Earth rotation, the “universal time” used in this alternate equation should be with respect to the UT1 time scale. However, the use of Coordinated Universal Time (UTC) in the se calculations

WebTime based on position of stars, i.e. Earth's sidereal rotation period ∼ 23h 56m 4s. Local sidereal time is GMST (Greenwich mean sidereal time) minus longitude. At the vernal equinox (time in sky when Sun crosses the celestial equator as its declination is increasing), sidereal time = UT.
