Introduction


The Partial Lunar Eclipse of 1932 Sep 14 is visible from the following geographic regions:

  • eastern Americas, Europe, Africa, Asia, Australia

The diagram to the right depicts the Moon's path with respect to Earth's umbral and penumbral shadows. Below it is a map showing the geographic regions of eclipse visibility.

The instant of greatest eclipse takes place on 1932 Sep 14 at 21:00:60 TD (21:00:36 UT1). This is 4.8 days before the Moon reaches apogee. During the eclipse, the Moon is in the constellation Pisces. The synodic month in which the eclipse takes place has a Brown Lunation Number of 120.

The eclipse belongs to Saros 136 and is number 15 of 72 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 umbral eclipse magnitude of 0.9752 and a partial eclipse duration of 204.0 minutes. Gamma has a value of 0.4664.

The partial lunar eclipse of 1932 Sep 14 is preceded two weeks earlier by a total solar eclipse on 1932 Aug 31.

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., TD = UT1 + ΔT). ΔT has a value of 23.9 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 Lunar Eclipse of 1932 Sep 14 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 23.9 seconds for this eclipse.
