Introduction

The Penumbral Lunar Eclipse of 2056 Jul 26 is visible from the following geographic regions:

  • 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 2056 Jul 26 at 18:43:25 TD (18:41:55 UT1). This is 4.3 days after the Moon reaches perigee. During the eclipse, the Moon is in the constellation Capricornus. The synodic month in which the eclipse takes place has a Brown Lunation Number of 1652.

The eclipse belongs to Saros 149 and is number 5 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.

The penumbral lunar eclipse of 2056 Jul 26 is preceded two weeks earlier by a annular solar eclipse on 2056 Jul 12.

Another lunar eclipse occurs one synodic month before the 2056 Jul 26 eclipse. It is the penumbral lunar eclipse of 2056 Jun 27.

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 89.5 seconds for this eclipse.

The following links provide maps and data for the eclipse.

Eclipse Predictions

Predictions for the Penumbral Lunar Eclipse of 2056 Jul 26 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 89.5 seconds for this eclipse.
