Introduction
The Partial Solar Eclipse of -1252 Apr 04 (1253 Apr 04 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 -1252 Apr 04 at 18:58:37 TD (10:38:26 UT1). This is 5.1 days before the Moon reaches apogee. During the eclipse, the Sun is in the constellation Aries. The synodic month in which the eclipse takes place has a Brown Lunation Number of -39266.
The eclipse belongs to Saros 9 and is number 74 of 74 eclipses in the series. Thus, the -1252 Apr 04 event is the last eclipse of 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 an extremely shallow partial eclipse. It has an eclipse magnitude of only 0.0231, while Gamma has a value of -1.5422. This is a very deep partial eclipse. It has an eclipse magnitude of 0.0231, while Gamma has a value of -1.5422.
The partial solar eclipse of -1252 Apr 04 is followed two weeks later by a total lunar eclipse on -1252 Apr 20.
Another solar eclipse occurs one synodic month after the -1252 Apr 04 eclipse. It is the partial solar eclipse of -1252 May 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 30010.9 seconds for this eclipse. The uncertainty in ΔT is 1193.7 seconds corresponding to a standard error in longitude of the eclipse path of ± 4.99°.
