Introduction


The Penumbral Lunar Eclipse of 2020 Jun 05 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 2020 Jun 05 at 19:26:14 TD (19:25:05 UT1). This is 2.7 days after the Moon reaches perigee. During the eclipse, the Moon is in the constellation Ophiuchus. The synodic month in which the eclipse takes place has a Brown Lunation Number of 1205.

The eclipse belongs to Saros 111 and is number 67 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 2020 Jun 05 is followed two weeks later by a annular solar eclipse on 2020 Jun 21.

Another lunar eclipse occurs one synodic month after the 2020 Jun 05 eclipse. It is the penumbral lunar eclipse of 2020 Jul 05.

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 69.7 seconds for this eclipse.

The following links provide maps and data for the eclipse.

At time t1 (decimal hours), each besselian element is evaluated by:

x = x0 + x1*t + x2*t2 + x3*t3 (or x = Σ [xn*tn]; n = 0 to 3)

where: t = t1 - t0 (decimal hours) and t0 = 19.000

Eclipse Predictions

Predictions for the Penumbral Lunar Eclipse of 2020 Jun 05 were generated using the JPL DE406 solar and lunar ephemerides. The lunar coordinates were calculated with respect to the Moon's Center of Mass. 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 69.7 seconds for this eclipse.
