Introduction
The Hybrid Solar Eclipse of -1438 Oct 16 (1439 Oct 16 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 -1438 Oct 16 at 02:34:32 TD (17:12:04 UT1). This is 2.7 days before the Moon reaches perigee. During the eclipse, the Sun is in the constellation Libra. The synodic month in which the eclipse takes place has a Brown Lunation Number of -41560.
The eclipse belongs to Saros 30 and is number 35 of 83 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 -1438 Oct 16 is one of the rare hybrid solar eclipses. In this particular case the eclipse path starts out as annular. Further down the track it changes to total and then back to annular before the path ends.
The hybrid solar eclipse of -1438 Oct 16 is preceded two weeks earlier by a penumbral lunar eclipse on -1438 Sep 30.
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 33747.8 seconds for this eclipse. The uncertainty in ΔT is 1708.5 seconds corresponding to a standard error in longitude of the eclipse path of ± 7.14°.
