A partial lunar eclipse will occur at the Moon's descending node of orbit on Thursday, September 28, 2034,[1] with an umbral magnitude of 0.0155. 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 1.9 days before perigee (on September 30, 2034, at 0:15 UTC), the Moon's apparent diameter will be larger.[2]
This will the second-shortest partial lunar eclipse in the 21st century, lasting 26 minutes and 42 seconds. On February 13, 2082, a slightly shorter partial eclipse will occur, lasting 25 minutes and 30 seconds.[3]
Visibility
The eclipse will be completely visible over eastern North America, South America, west Africa, and western Europe, seen rising over western North America and setting over east Africa and eastern Europe.[4]

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.
