The eclipse belongs to Saros 128 and is number 58 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 annular solar eclipse of 2012 May 20 is followed two weeks later by a partial lunar eclipse on 2012 Jun 04.
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 66.8 seconds for this eclipse.
