Introduction
The Total Solar Eclipse of -1990 Jul 02 (1991 Jul 02 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 -1990 Jul 02 at 10:29:02 TD (21:39:29 UT1). This is 0.5 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 -48391.
The eclipse belongs to Saros 24 and is number 9 of 72 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 -1990 Jul 02 is a relatively long total eclipse with a duration at greatest eclipse of 04m30s. It has an eclipse magnitude of 1.0608.
The total solar eclipse of -1990 Jul 02 is preceded two weeks earlier by a total lunar eclipse on -1990 Jun 17.
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 46172.7 seconds for this eclipse. The uncertainty in ΔT is 3687.9 seconds corresponding to a standard error in longitude of the eclipse path of ± 15.41°.
