A penumbral lunar eclipse will occur at the Moon’s ascending node of orbit on Saturday, May 7, 2107,[1] with an umbral magnitude of −0.9356. 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 will be near the average diameter because it will occur 6.8 days after perigee (on April 30, 2107, at 10:00 UTC) and 6.9 days before apogee (on May 14, 2107, at 1:50 UTC).[2]
This eclipse will be too small to be visually perceptible.
The eclipse will be completely visible over much of North and South America, western Europe, west and southern Africa, and Antarctica.

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. The first and last eclipse in this sequence is separated by one synodic month.
