Introduction
The Total Solar Eclipse of -0639 May 07 (0640 May 07 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 -0639 May 07 at 04:22:57 TD (23:02:40 UT1). This is 1.9 days after the Moon reaches perigee. During the eclipse, the Sun is in the constellation Taurus. The synodic month in which the eclipse takes place has a Brown Lunation Number of -31683.
The eclipse belongs to Saros 47 and is number 38 of 72 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 solar eclipse of -0639 May 07 is a relatively long total eclipse with a duration at greatest eclipse of 05m10s. It has an eclipse magnitude of 1.0580.
The total solar eclipse of -0639 May 07 is preceded two weeks earlier by a penumbral lunar eclipse on -0639 Apr 23, and it is followed two weeks later by a penumbral lunar eclipse on -0639 May 22.
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 19217.3 seconds for this eclipse. The uncertainty in ΔT is 483.6 seconds corresponding to a standard error in longitude of the eclipse path of ± 2.02°.
