Introduction
The Total Solar Eclipse of -1789 Mar 04 (1790 Mar 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 -1789 Mar 04 at 15:38:54 TD (04:08:20 UT1). This is 0.5 days before the Moon reaches perigee. 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 -45909.
The eclipse belongs to Saros 11 and is number 40 of 76 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 -1789 Mar 04 is a relatively long total eclipse with a duration at greatest eclipse of 05m36s. It has an eclipse magnitude of 1.0677.
The total solar eclipse of -1789 Mar 04 is preceded two weeks earlier by a penumbral lunar eclipse on -1789 Feb 17, and it is followed two weeks later by a penumbral lunar eclipse on -1789 Mar 19.
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 41433.5 seconds for this eclipse. The uncertainty in ΔT is 2892.7 seconds corresponding to a standard error in longitude of the eclipse path of ± 12.09°.
