Introduction
The Total Solar Eclipse of -1221 Aug 18 (1222 Aug 18 BCE) 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 -1221 Aug 18 at 08:53:60 TD (00:43:59 UT1). This is 2.3 days after the Moon reaches perigee. During the eclipse, the Sun is in the constellation Virgo. The synodic month in which the eclipse takes place has a Brown Lunation Number of -38878.
The eclipse belongs to Saros 35 and is number 37 of 84 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 total solar eclipse of -1221 Aug 18 is preceded two weeks earlier by a penumbral lunar eclipse on -1221 Aug 04, and it is followed two weeks later by a penumbral lunar eclipse on -1221 Sep 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 29400.5 seconds for this eclipse. The uncertainty in ΔT is 1114.4 seconds corresponding to a standard error in longitude of the eclipse path of ± 4.66°.
