Introduction

The Total Lunar Eclipse of 1936 Jan 08 is visible from the following geographic regions:

  • North North America, 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 1936 Jan 08 at 18:09:58 TD (18:09:34 UT1). This is 6.2 days before the Moon reaches apogee. During the eclipse, the Moon is in the constellation Gemini. The synodic month in which the eclipse takes place has a Brown Lunation Number of 161.

The eclipse belongs to Saros 133 and is number 22 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.

This is a very shallow total eclipse. It has an umbral eclipse magnitude of only 1.0173 and a duration of totality lasting 20.8 minutes. Gamma has a value of -0.4429.

The total lunar eclipse of 1936 Jan 08 is preceded two weeks earlier by a annular solar eclipse on 1935 Dec 25.

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 23.8 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 = 18.000

Eclipse Predictions

Predictions for the Total Lunar Eclipse of 1936 Jan 08 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 Earth's umbral and penumbral shadows were calculated using the Danjon methodusing a mean mid-latitude ellipticity to compensate for the opacity of the terrestrial atmosphere.

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 23.8 seconds for this eclipse.
