Introduction

The Partial Lunar Eclipse of 2028 Jul 06 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 2028 Jul 06 at 18:20:57 TD (18:19:44 UT1). This is 5.2 days before the Moon reaches apogee. 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 1305.

The eclipse belongs to Saros 120 and is number 58 of 83 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.

The partial lunar eclipse of 2028 Jul 06 is followed two weeks later by a total solar eclipse on 2028 Jul 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 73.2 seconds for this eclipse.

The following links provide maps and data for the eclipse.

Eclipse Predictions

Predictions for the Partial Lunar Eclipse of 2028 Jul 06 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 73.2 seconds for this eclipse.
