Introduction
The Hybrid Solar Eclipse of -0316 Jul 04 (0317 Jul 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 -0316 Jul 04 at 10:52:54 TD (06:56:05 UT1). This is 5.0 days before the Moon reaches perigee. During the eclipse, the Sun is in the constellation Cancer. The synodic month in which the eclipse takes place has a Brown Lunation Number of -27686.
The eclipse belongs to Saros 70 and is number 29 of 84 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 -0316 Jul 04 is one of the rare hybrid solar eclipses. In this particular case the eclipse path starts out as annular but later changes to total. It is a relatively long hybrid eclipse with a duration at greatest eclipse of 01m30s. The eclipse magnitude is 1.0137, while Gamma has a value of -0.5848.
The hybrid solar eclipse of -0316 Jul 04 is preceded two weeks earlier by a partial lunar eclipse on -0316 Jun 18.
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 14209.6 seconds for this eclipse. The uncertainty in ΔT is 364.8 seconds corresponding to a standard error in longitude of the eclipse path of ± 1.52°.
