Introduction


The Partial Solar Eclipse of 1975 Nov 03 is visible from the following geographic regions:

  • Partial Eclipse: south South America, Antarctica

The map to the right depicts the geographic regions of eclipse visibility. 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 1975 Nov 03 at 13:15:54 TD (13:15:08 UT1). This is 1.5 days after the Moon reaches perigee. During the eclipse, the Sun is in the constellation Libra. The synodic month in which the eclipse takes place has a Brown Lunation Number of 654.

The eclipse belongs to Saros 123 and is number 51 of 70 eclipses in the series. All eclipses in this series occur at the Moon’s ascending node. The Moon moves southward with respect to the node with each succeeding eclipse in the series and gamma decreases.

This is a very deep partial eclipse. It has an eclipse magnitude of 0.9588, while Gamma has a value of -1.0248.

The partial solar eclipse of 1975 Nov 03 is followed two weeks later by a total lunar eclipse on 1975 Nov 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 46.3 seconds for this eclipse.

The following links provide maps and data for the eclipse.

Eclipse Predictions

Predictions for the Partial Solar Eclipse of 1975 Nov 03 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 46.3 seconds for this eclipse.
