A penumbral lunar eclipse occurred on Friday, 5 May 2023, the first of two lunar eclipses in 2023. The moon's apparent diameter was 0.1% larger than average since it occurred 5.5 days before perigee (Perigee on 11 May 2023). This was the deepest penumbral eclipse (with –0.0457 magnitude) since February 2017 and until September 2042.[1]

Saros series

[edit]

Metonic series

[edit]

This eclipse is the last of four Metonic cycle lunar eclipses on the same date, 4–5 May, each separated by 19 years:

The metonic cycle repeats nearly exactly every 19 years and represents a Saros cycle plus one lunar year. Because it occurs on the same calendar date, the Earth's shadow will in nearly the same location relative to the background stars.

Metonic events: May 4 and October 28
