Introduction


The Annular Solar Eclipse of 1945 Jan 14 is visible from the following geographic regions:

  • Partial Eclipse: Madagascar, Antarctica, Australia, New Zealand
  • Annular Eclipse: South Africa, Tasmania

The instant of greatest eclipse takes place on 1945 Jan 14 at 05:01:43 TD (05:01:16 UT1). This is 3.5 days before the Moon reaches perigee. During the eclipse, the Sun is in the constellation Sagittarius. The synodic month in which the eclipse takes place has a Brown Lunation Number of 273.

The eclipse belongs to Saros 140 and is number 25 of 71 eclipses in the series. All eclipses in this series occur at the Moon’s 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 1945 Jan 14 is a very short annular eclipse with a duration at greatest eclipse of 00m15s. It has an eclipse magnitude of 0.9970.

The annular solar eclipse of 1945 Jan 14 is preceded two weeks earlier by a penumbral lunar eclipse on 1944 Dec 29.

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 26.8 seconds for this eclipse.

The following links provide maps and data for the eclipse.

Eclipse Predictions

Predictions for the Annular Solar Eclipse of 1945 Jan 14 were generated using the JPL DE405 solar and lunar ephemerides. The lunar coordinates were calculated with respect to the Moon's Center of Mass. The 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 26.8 seconds for this eclipse.
