A penumbral lunar eclipse occurred at the Moon’s descending node of orbit on Sunday, July 5, 2020,{{cite web|title=July 4–5, 2020 Penumbral Lunar Eclipse|url=https://www.timeanddate.com/eclipse/lunar/2020-july-5|publisher=timeanddate|access-date=17 November 2024}} with an umbral magnitude of −0.6422. 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. The Moon's apparent diameter was near the average diameter because it occurred 5.3 days after perigee (on June 29, 2020, at 22:10 UTC) and 7.5 days before apogee (on July 12, 2020, at 15:30 UTC).{{cite web|title=Moon Distances for London, United Kingdom, England|url=https://www.timeanddate.com/astronomy/moon/distance.html?year=2020&n=136|publisher=timeanddate|access-date=17 November 2024}}
This eclipse was the third of four penumbral lunar eclipses in 2020, with the others occurring on January 10, June 5, and November 30.
Visibility
The eclipse was completely visible over North and South America and west Africa, seen rising over northwestern North America and the central Pacific Ocean and setting over much of Africa and western Europe.{{cite web|title=Penumbral Lunar Eclipse of 2020 Jul 05|url=https://eclipse.gsfc.nasa.gov/LEplot/LEplot2001/LE2020Jul05N.pdf|publisher=NASA|access-date=17 November 2024}}

Eclipse season
{{See also|Eclipse cycle}}
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. The first and last eclipse in this sequence is separated by one synodic month.
