Introduction
The Annular Solar Eclipse of -1725 Mar 17 (1726 Mar 17 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 -1725 Mar 17 at 04:01:22 TD (16:55:07 UT1). This is 5.6 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 -45117.
The eclipse belongs to Saros 2 and is number 64 of 73 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 -1725 Mar 17 is a very short annular eclipse with a duration at greatest eclipse of 00m02s. It has an eclipse magnitude of 0.9997.
The annular solar eclipse of -1725 Mar 17 is followed two weeks later by a partial lunar eclipse on -1725 Mar 31.
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 39975.2 seconds for this eclipse. The uncertainty in ΔT is 2657.0 seconds corresponding to a standard error in longitude of the eclipse path of ± 11.10°.
