Definition of Time. Correction of Mean to Sidereal Time In calculating the Sidereal Time for a given moment of birth, add the solar hours elapsed since the previous noon to the Sun's noon position at Greenwich as given in the ephemeris in Sidereal Time. (Apolo's Note: this applies only if you are using an ephemeris with readings for noon; if using one for midnight, which is easier, then add the solar hours elapsed since midnight on the start of the day of birth.) This requires the further addition of a little less than ten seconds (9.86 seconds) per hour to compensate for the difference between solar and sidereal time.

[A further correction for longitude is made by way of adjusting the Greenwich position to that of the place for which the correction is made.]
