Local Sidereal Time

Local sidereal time is the most useful form of since it gives the of a transiting celestial object at a given location. To compute the current local sidereal time LST, consult the current Astronomical Almanac. Look up the "G.

LOCAL SIDEREAL TIME
Local sidereal time (abbreviated LST) is local time measured by the apparent motion of the stars (instead of the motion of the Sun).

LOCAL SIDEREAL TIME
Local (abbreviated LST) is local time measured by the apparent motion of the stars (instead of the motion of the Sun). LST is measured by the that is currently at the observer's of the local sky.

E = inclination of Earth's equatorial plane to the ecliptic or obliquity of the ecliptic. For values referred to the standard equinox J2000.0 use 23.4392911°, for J1950.0 use 23.4457889°.

This is timekeeping based on the sidereal day, and hence it runs ahead significantly with respect to solar-based time. Do not confuse with astronomical time. Local sidereal time is equal to the hour angle of the first point of Aries and is, ...
