Introduction

The Penumbral Lunar Eclipse of 2092 Jul 19 is visible from the following geographic regions:

  • eastern North America, South America, Europe, Africa, western Asia

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 2092 Jul 19 at 00:41:57 TD (00:39:58 UT1). This is 2.0 days after the Moon reaches perigee. During the eclipse, the Moon is in the constellation Sagittarius. The synodic month in which the eclipse takes place has a Brown Lunation Number of 2097.

The eclipse belongs to Saros 111 and is number 71 of 71 eclipses in the series. Thus, the 2092 Jul 19 event is the last eclipse of 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 penumbral eclipse. It has a penumbral eclipse magnitude of only 0.0634 and a penumbral eclipse duration of 68.6 minutes. Gamma has a value of 1.5132.

The penumbral lunar eclipse of 2092 Jul 19 is followed two weeks later by a annular solar eclipse on 2092 Aug 03.

Another lunar eclipse occurs one synodic month after the 2092 Jul 19 eclipse. It is the penumbral lunar eclipse of 2092 Aug 17.

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 119.5 seconds for this eclipse.

The following links provide maps and data for the eclipse.

Eclipse Predictions

Predictions for the Penumbral Lunar Eclipse of 2092 Jul 19 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 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 119.5 seconds for this eclipse.
