Introduction
The Annular Solar Eclipse of 1822 Feb 21 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 1822 Feb 21 at 19:40:40 TD (19:40:29 UT1). This is 3.6 days before the Moon reaches perigee. During the eclipse, the Sun is in the constellation Aquarius. The synodic month in which the eclipse takes place has a Brown Lunation Number of -1247.
The eclipse belongs to Saros 137 and is number 25 of 70 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 1822 Feb 21 is a very short annular eclipse with a duration at greatest eclipse of 00m02s. It has an eclipse magnitude of 0.9996.
The annular solar eclipse of 1822 Feb 21 is preceded two weeks earlier by a partial lunar eclipse on 1822 Feb 06.
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 10.9 seconds for this eclipse.
