Introduction
The Hybrid Solar Eclipse of 2172 Oct 17 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 2172 Oct 17 at 16:01:36 TD (15:57:53 UT1). This is 3.2 days before the Moon reaches perigee. During the eclipse, the Sun is in the constellation Virgo. The synodic month in which the eclipse takes place has a Brown Lunation Number of 3090.
The eclipse belongs to Saros 146 and is number 36 of 76 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 solar eclipse of 2172 Oct 17 is one of the rare hybrid solar eclipses. In this particular case the eclipse path starts out as annular but later changes to total. It is a relatively long hybrid eclipse with a duration at greatest eclipse of 01m34s. The eclipse magnitude is 1.0174, while Gamma has a value of -0.1484.
The hybrid solar eclipse of 2172 Oct 17 is preceded two weeks earlier by a penumbral lunar eclipse on 2172 Oct 02, and it is followed two weeks later by a penumbral lunar eclipse on 2172 Oct 31.
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 223.4 seconds for this eclipse.
