Introduction
The Annular Solar Eclipse of 1691 Feb 28 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 1691 Feb 28 at 04:37:41 TD (04:37:32 UT1). This is 4.0 days after the Moon reaches apogee. During the eclipse, the Sun is in the constellation Aquarius. The synodic month in which the eclipse takes place has a Brown Lunation Number of -2867.
The eclipse belongs to Saros 125 and is number 36 of 73 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 1691 Feb 28 is a relatively long annular eclipse with a duration at greatest eclipse of 06m40s. It has an eclipse magnitude of 0.9414.
The annular solar eclipse of 1691 Feb 28 is preceded two weeks earlier by a penumbral lunar eclipse on 1691 Feb 12, and it is followed two weeks later by a penumbral lunar eclipse on 1691 Mar 14.
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 8.4 seconds for this eclipse.
