A partial lunar eclipse occurred at the Moon’s descending node of orbit on Tuesday, July 16, 2019,{{cite web|title=July 16–17, 2019 Partial Lunar Eclipse|url=https://www.timeanddate.com/eclipse/lunar/2019-july-16|publisher=timeanddate|access-date=17 November 2024}} with an umbral magnitude of 0.6544. A lunar eclipse occurs when the Moon moves into the Earth's shadow, causing the Moon to be darkened. A partial lunar eclipse occurs when one part of the Moon is in the Earth's umbra, while the other part is in 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 3.9 days after apogee (on July 20, 2019, at 20:00 UTC), the Moon's apparent diameter was smaller.{{cite web|title=Moon Distances for London, United Kingdom, England|url=https://www.timeanddate.com/astronomy/moon/distance.html?year=2019&n=136|publisher=timeanddate|access-date=17 November 2024}}
Visibility
The eclipse was completely visible over Africa, eastern Europe, Antarctica, and west, central, and south Asia, seen rising over the South America, western Europe, and west Africa, and setting over east Asia and Australia.{{cite web|title=Partial Lunar Eclipse of 2019 Jul 16|url=https://eclipse.gsfc.nasa.gov/LEplot/LEplot2001/LE2019Jul16P.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.
