Introduction
The Hybrid Solar Eclipse of 1669 Apr 30 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 1669 Apr 30 at 05:26:06 TD (05:25:42 UT1). This is 6.1 days after the Moon reaches perigee. During the eclipse, the Sun is in the constellation Aries. The synodic month in which the eclipse takes place has a Brown Lunation Number of -3137.
The eclipse belongs to Saros 123 and is number 34 of 70 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 1669 Apr 30 is one of the rare hybrid solar eclipses. In this particular case the eclipse path starts out as annular. Further down the track it changes to total and then back to annular before the path ends. It is a very short hybrid eclipse with a duration at greatest eclipse of 00m22s. The eclipse magnitude is 1.0036, while Gamma has a value of -0.0170.
The hybrid solar eclipse of 1669 Apr 30 is preceded two weeks earlier by a penumbral lunar eclipse on 1669 Apr 16, and it is followed two weeks later by a penumbral lunar eclipse on 1669 May 15.
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 23.8 seconds for this eclipse.
