Introduction
The Partial Solar Eclipse of -1209 Dec 31 (1210 Dec 31 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 -1209 Dec 31 at 21:15:01 TD (13:08:60 UT1). This is 1.9 days after the Moon reaches perigee. 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 -38725.
The eclipse belongs to Saros 51 and is number 12 of 85 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.
This is a very deep partial eclipse. It has an eclipse magnitude of 0.2490, while Gamma has a value of 1.4061.
The partial solar eclipse of -1209 Dec 31 is preceded two weeks earlier by a total lunar eclipse on -1209 Dec 17.
Another solar eclipse occurs one synodic month before the -1209 Dec 31 eclipse. It is the partial solar eclipse of -1209 Dec 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 29161.6 seconds for this eclipse. The uncertainty in ΔT is 1083.7 seconds corresponding to a standard error in longitude of the eclipse path of ± 4.53°.
