Introduction
The Annular Solar Eclipse of 0771 Jan 20 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 0771 Jan 20 at 20:20:31 TD (19:27:38 UT1). This is 0.8 days after the Moon reaches apogee. During the eclipse, the Sun is in the constellation Capricornus. The synodic month in which the eclipse takes place has a Brown Lunation Number of -14247.
The eclipse belongs to Saros 82 and is number 60 of 71 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 0771 Jan 20 is an exceptionally long annular eclipse with a duration at greatest eclipse of 09m31s. It has an eclipse magnitude of 0.9125.
The annular solar eclipse of 0771 Jan 20 is followed two weeks later by a partial lunar eclipse on 0771 Feb 04.
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 3172.7 seconds for this eclipse. The uncertainty in ΔT is 88.0 seconds corresponding to a standard error in longitude of the eclipse path of ± 0.37°.
