Introduction
The Total Lunar Eclipse of 2061 Apr 04 is visible from the following geographic regions:
- eastern Americas, 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 2061 Apr 04 at 21:54:05 TD (21:52:32 UT1). This is 3.8 days before the Moon reaches apogee. During the eclipse, the Moon is in the constellation Virgo. The synodic month in which the eclipse takes place has a Brown Lunation Number of 1710.
The eclipse belongs to Saros 123 and is number 55 of 72 eclipses in the series. All eclipses in this series occur at the Moons 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 1.0360 and a duration of totality lasting 30.9 minutes. Gamma has a value of 0.4300.
The total lunar eclipse of 2061 Apr 04 is followed two weeks later by a total solar eclipse on 2061 Apr 20.
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 92.8 seconds for this eclipse.
