A penumbral lunar eclipse occurred at the Moon’s descending node of orbit on Friday, May 5, 2023,{{cite web|title=May 5–6, 2023 Penumbral Lunar Eclipse|url=https://www.timeanddate.com/eclipse/lunar/2023-may-5|publisher=timeanddate|access-date=18 November 2024}} with an umbral magnitude of −0.0438. A lunar eclipse occurs when the Moon moves into the Earth's shadow, causing the Moon to be darkened. A penumbral lunar eclipse occurs when part or all of the Moon's near side passes into the Earth's penumbra. Unlike a solar eclipse, which can only be viewed from a relatively small area of the world, a lunar eclipse may be viewed from anywhere on the night side of Earth. Occurring about 5.2 days before perigee (on May 11, 2023, at 1:05 UTC), the Moon's apparent diameter was larger.{{cite web|title=Moon Distances for London, United Kingdom, England|url=https://www.timeanddate.com/astronomy/moon/distance.html?year=2023&n=136|publisher=timeanddate|access-date=18 November 2024}}

This was the deepest penumbral eclipse (with –0.0438 magnitude) since February 2017 and until August 2053.{{cite web | url=https://www.timeanddate.com/eclipse/lunar/2023-may-5 | title=Penumbral Lunar Eclipse on May 5–6, 2023 – Where and when to See }}

Eclipse season

This eclipse is part of an eclipse season, a period, roughly every six months, when eclipses occur. Only two (or occasionally three) eclipse seasons occur each year, and each season lasts about 35 days and repeats just short of six months (173 days) later; thus two full eclipse seasons always occur each year. Either two or three eclipses happen each eclipse season. In the sequence below, each eclipse is separated by a fortnight.
