The instant of greatest eclipse takes place on 2085 Dec 16 at 22:37:48 TD (22:35:55 UT1). This is 3.7 days before the Moon reaches perigee. During the eclipse, the Sun is in the constellation Ophiuchus. The synodic month in which the eclipse takes place has a Brown Lunation Number of 2016.
The eclipse belongs to Saros 143 and is number 27 of 72 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 2085 Dec 16 is a very short annular eclipse with a duration at greatest eclipse of 00m19s. It has an eclipse magnitude of 0.9971.
The annular solar eclipse of 2085 Dec 16 is preceded two weeks earlier by a penumbral lunar eclipse on 2085 Dec 01.
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 113.2 seconds for this eclipse.
