Introduction
The Partial Solar Eclipse of 2843 Apr 20 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 2843 Apr 20 at 22:09:19 TD (21:17:54 UT1). This is 1.5 days after the Moon reaches apogee. 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 11383.
The eclipse belongs to Saros 181 and is number 1 of 71 eclipses in the series. Thus, the 2843 Apr 20 event is the very first eclipse of 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.
This is an extremely shallow partial eclipse. It has an eclipse magnitude of only 0.0208, while Gamma has a value of 1.5547. This is a very deep partial eclipse. It has an eclipse magnitude of 0.0208, while Gamma has a value of 1.5547.
The partial solar eclipse of 2843 Apr 20 is preceded two weeks earlier by a total lunar eclipse on 2843 Apr 06.
Another solar eclipse occurs one synodic month before the 2843 Apr 20 eclipse. It is the partial solar eclipse of 2843 Mar 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 3084.6 seconds for this eclipse. The uncertainty in ΔT is 698.4 seconds corresponding to a standard error in longitude of the eclipse path of ± 2.92°.
