Introduction
The Annular Solar Eclipse of 1256 Dec 18 is visible from the geographic regions shown on the map to the right. Click on the map to enlarge it. For an explanation of the features appearing in the map, see Key to Solar Eclipse Maps.
The instant of greatest eclipse takes place on 1256 Dec 18 at 13:04:34 TD (12:54:55 UT1). This is 0.5 days after the Moon reaches apogee. During the eclipse, the Sun is in the constellation Sagittarius. The synodic month in which the eclipse takes place has a Brown Lunation Number of -8237.
The eclipse belongs to Saros 110 and is number 45 of 72 eclipses in the series. All eclipses in this series occur at the Moons descending node. The Moon moves northward with respect to the node with each succeeding eclipse in the series and gamma increases.
The solar eclipse of 1256 Dec 18 is an exceptionally long annular eclipse with a duration at greatest eclipse of 11m38s. It has an eclipse magnitude of 0.9172.
The annular solar eclipse of 1256 Dec 18 is preceded two weeks earlier by a penumbral lunar eclipse on 1256 Dec 03, and it is followed two weeks later by a penumbral lunar eclipse on 1257 Jan 02.
These eclipses all take place during a single eclipse season.
The eclipse predictions are given in both Terrestrial Dynamical Time (TD) and Universal Time (UT1). The parameter ΔT is used to convert between these two times (i.e., UT1 = TD - ΔT). ΔT has a value of 578.3 seconds for this eclipse.
