Introduction


The Partial Solar Eclipse of 1916 Dec 24 is visible from the following geographic regions:

  • Partial Eclipse: 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 1916 Dec 24 at 20:46:22 TD (20:46:02 UT1). This is 1.2 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 -74.

The eclipse belongs to Saros 111 and is number 78 of 79 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 an extremely shallow partial eclipse. It has an eclipse magnitude of only 0.0115, while Gamma has a value of -1.5321. This is a very deep partial eclipse. It has an eclipse magnitude of 0.0115, while Gamma has a value of -1.5321.

The partial solar eclipse of 1916 Dec 24 is followed two weeks later by a total lunar eclipse on 1917 Jan 08.

Another solar eclipse occurs one synodic month after the 1916 Dec 24 eclipse. It is the partial solar eclipse of 1917 Jan 23.

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 19.3 seconds for this eclipse.

The following links provide maps and data for the eclipse.

At time t1 (decimal hours), each besselian element is evaluated by:

x = x0 + x1*t + x2*t2 + x3*t3 (or x = Σ [xn*tn]; n = 0 to 3)

where: t = t1 - t0 (decimal hours) and t0 = 21.000

Eclipse Predictions

Predictions for the Partial Solar Eclipse of 1916 Dec 24 were generated using the JPL DE406 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 19.3 seconds for this eclipse.
