USNO Circular 141

Lunar Limb Profiles for Solar Eclipses

Julena S. Duncombe
U.S. Naval Observatory
March 1973

Introduction:

This Circular contains selected lunar limb profiles designed for use in solar eclipse predictions. These profiles, used in accordance with provided criteria, allow the eclipse observer to predict the effect of lunar limb irregularities on the time of second and third contacts for any site along the eclipse path. The arguments of these profiles range in topocentric longitude from +6° to -6°; topocentric latitude is 0° because solar eclipses always occur near the nodes of the lunar orbit.
