A penumbral lunar eclipse occurred at the MoonâÂÂs descending node of orbit on Wednesday, June 13, 1984, with an umbral magnitude of âÂÂ0.9414. 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. Occurring about 6.1 days after perigee (on June 7, 1984, at 12:25 UTC), the Moon's apparent diameter was larger.
This minor penumbral eclipse was visually imperceptible, but marked the first lunar eclipse in Lunar Saros 149.
The eclipse was completely visible over the eastern half of Asia, Australia, and Antarctica, seen rising over Madagascar and central Asia and setting over the eastern Pacific Ocean.
Shown below is a table displaying details about this particular solar eclipse. It describes various parameters pertaining to this eclipse.
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.
