A partial lunar eclipse will occur at the Moon’s descending node of orbit on Friday, June 28, 2075,[1] with an umbral magnitude of 0.6235. 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 only about 5.5 hours after perigee (on June 28, 2075, at 4:10 UTC), the Moon's apparent diameter will be larger.[2]
Visibility
[edit]The eclipse will be completely visible over eastern Australia, western North America, Antarctica, and the central and eastern Pacific Ocean, seen rising over east Asia and western Australia and setting over much of North and South America.[3]

Eclipse season
[edit]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.

Lunar eclipses of 2074–2078
[edit]This eclipse is a member of a semester series. An eclipse in a semester series of lunar eclipses repeats approximately every 177 days and 4 hours (a semester) at alternating nodes of the Moon's orbit.[5]
The penumbral lunar eclipses on February 11, 2074 and August 7, 2074 occur in the previous lunar year eclipse set, and the penumbral lunar eclipses on April 27, 2078 and October 21, 2078 occur in the next lunar year eclipse set.
