The instant of greatest eclipse takes place on 2023 Apr 20 at 04:17:56 TD (04:16:45 UT1). This is 4.1 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 1241.
The eclipse belongs to Saros 129 and is number 52 of 80 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 2023 Apr 20 is one of the rare hybrid solar eclipses. In this particular case the eclipse path starts out as annular. Further down the track it changes to total and then back to annular before the path ends.
The hybrid solar eclipse of 2023 Apr 20 is followed two weeks later by a penumbral lunar eclipse on 2023 May 05.
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 70.8 seconds for this eclipse.
