Introduction
The Total Solar Eclipse of 0785 Apr 13 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 0785 Apr 13 at 21:35:38 TD (20:44:44 UT1). This is 2.1 days after 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 -14071.
The eclipse belongs to Saros 80 and is number 63 of 71 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.
This total eclipse is unsual in that it does NOT have a northern path limit. Instead, one edge of the umbral shadow falls off into space throughout the eclipse. Gamma has a value of 0.9956.
The total solar eclipse of 0785 Apr 13 is followed two weeks later by a total lunar eclipse on 0785 Apr 29.
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 3054.6 seconds for this eclipse. The uncertainty in ΔT is 85.6 seconds corresponding to a standard error in longitude of the eclipse path of ± 0.36°.
