Introduction
The Annular Solar Eclipse of 2791 Jan 26 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 2791 Jan 26 at 12:45:13 TD (11:59:39 UT1). This is 3.7 days after the Moon reaches perigee. 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 10737.
The eclipse belongs to Saros 163 and is number 29 of 72 eclipses in the series. All eclipses in this series occur at the Moons ascending node. The Moon moves southward with respect to the node with each succeeding eclipse in the series and gamma decreases.
The solar eclipse of 2791 Jan 26 is a very short annular eclipse with a duration at greatest eclipse of 00m15s. It has an eclipse magnitude of 0.9975.
The annular solar eclipse of 2791 Jan 26 is preceded two weeks earlier by a penumbral lunar eclipse on 2791 Jan 12, and it is followed two weeks later by a penumbral lunar eclipse on 2791 Feb 11.
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 2733.8 seconds for this eclipse. The uncertainty in ΔT is 628.4 seconds corresponding to a standard error in longitude of the eclipse path of ± 2.63°.
