Introduction
The Partial Solar Eclipse of -1889 Dec 20 (1890 Dec 20 BCE) 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 -1889 Dec 20 at 13:12:11 TD (01:03:06 UT1). This is 0.4 days before the Moon reaches perigee. During the eclipse, the Sun is in the constellation Capricornus. The synodic month in which the eclipse takes place has a Brown Lunation Number of -47136.
The eclipse belongs to Saros -8 and is number 65 of 74 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.
This is a very deep partial eclipse. It has an eclipse magnitude of 0.6766, while Gamma has a value of 1.1767.
The partial solar eclipse of -1889 Dec 20 is followed two weeks later by a total lunar eclipse on -1888 Jan 04.
Another solar eclipse occurs one synodic month after the -1889 Dec 20 eclipse. It is the partial solar eclipse of -1888 Jan 18.
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 43744.3 seconds for this eclipse. The uncertainty in ΔT is 3275.1 seconds corresponding to a standard error in longitude of the eclipse path of ± 13.68°.
