Introduction

The Partial Lunar Eclipse of 2052 Oct 08 is visible from the following geographic regions:

  • eastern Asia, Australia, Americas

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 2052 Oct 08 at 10:45:58 TD (10:44:31 UT1). This is 2.2 days before the Moon reaches perigee. 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 1605.

The eclipse belongs to Saros 147 and is number 10 of 70 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 partial eclipse. It has an umbral eclipse magnitude of only 0.0832 and a partial eclipse duration of 63.9 minutes. Gamma has a value of -0.9727.

The partial lunar eclipse of 2052 Oct 08 is preceded two weeks earlier by a annular solar eclipse on 2052 Sep 22.

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 86.9 seconds for this eclipse.

The following links provide maps and data for the eclipse.

Eclipse Predictions

Predictions for the Partial Lunar Eclipse of 2052 Oct 08 were generated using the JPL DE430 solar and lunar ephemerides. The lunar coordinates were calculated with respect to the Moon's Center of Mass.

The elliptical shape of Earth's umbral and penumbral shadows were calculated using the Herald/Sinnott method of modeling Earth's shadows to compensate for the opacity of the terrestrial atmosphere (including the oblateness of Earth).

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 86.9 seconds for this eclipse.
