Introduction


The Partial Solar Eclipse of 1942 Mar 16 is visible from the following geographic regions:

  • Partial Eclipse: Antarctica

The instant of greatest eclipse takes place on 1942 Mar 16 at 23:37:07 TD (23:36:41 UT1). This is 6.4 days before the Moon reaches apogee. During the eclipse, the Sun is in the constellation Pisces. The synodic month in which the eclipse takes place has a Brown Lunation Number of 238.

The eclipse belongs to Saros 148 and is number 17 of 75 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.

This is a very deep partial eclipse. It has an eclipse magnitude of 0.6394, while Gamma has a value of -1.1908.

The partial solar eclipse of 1942 Mar 16 is preceded two weeks earlier by a total lunar eclipse on 1942 Mar 03.

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 25.4 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 = 0.000

Eclipse Predictions

Predictions for the Partial Solar Eclipse of 1942 Mar 16 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 25.4 seconds for this eclipse.
