Introduction
The Total Solar Eclipse of 1170 Aug 13 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 1170 Aug 13 at 20:46:46 TD (20:33:08 UT1). This is 1.1 days before the Moon reaches perigee. During the eclipse, the Sun is in the constellation Leo. The synodic month in which the eclipse takes place has a Brown Lunation Number of -9305.
The eclipse belongs to Saros 112 and is number 36 of 72 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 1170 Aug 13 is a relatively long total eclipse with a duration at greatest eclipse of 05m28s. It has an eclipse magnitude of 1.0645.
The total solar eclipse of 1170 Aug 13 is preceded two weeks earlier by a penumbral lunar eclipse on 1170 Jul 29, and it is followed two weeks later by a penumbral lunar eclipse on 1170 Aug 28.
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 817.7 seconds for this eclipse.
