Earth in constellation Libra with New Moon Sun in constellation Aries --------------------------------------------------------------------------------------------------------------------------------------------------------------------------- Penumbral lunar eclipse This event is visible to the naked eye from Tampa. FRI, 05 MAY 2023 FROM 11:15 EDT (15:15 UTC) TO 15:32 EDT (19:32 UTC) The Moon will pass through the Earth's shadow between 11:15 and 15:32 EDT, creating a penumbral lunar eclipse. The eclipse will be visible any location where the Moon is above the horizon at the time, including from Antarctica, Asia, Russia, Africa and Oceania. A penumbral eclipse Like other lunar eclipses, penumbral eclipses occur whenever the Earth passes between the Moon and Sun, such that it obscures the Sun's light and casts a shadow onto the Moon's surface. But unlike other kinds of eclipses, they are extremely subtle events to observe. In a penumbral eclipse the Moon passes through an outer region of the Earth's shadow called the penumbra. This is the outer part of the Earth's shadow, in which the Earth appears to cover part of the Sun's disk, but not all of it (see diagram below). As a result, the Moon's brightness will be reduced, as it is less strongly illuminated by the Sun, but the whole of the Moon's disk will remain illuminated to some degree. The effect is only perceptible to those with very astute vision, or in carefully controlled photographs. This is a rare occasion when the whole of the Moon's face will pass within the Earth's penumbra, and so the reduction of the Moon's brightness will be more perceptible than usual. Such events are called total penumbral lunar eclipses, and are rare because the statistical chance that the Moon will enter the Earth's umbra at some point is very high once it has passed fully within its penumbra, and this makes an eclipse a partial lunar eclipse.  The geometry of the Earth's shadow. Within the Earth's penumbral shadow, the planet covers some fraction the Sun's disk. Only within the smaller umbra does the Earth cover the entirety of the Sun's disk. Any areas of the Moon's surface that pass through the penumbra appear darker than usual as the Earth is obstructing some of the sunlight that usually illuminates them. Areas within the umbra, meanwhile, receive no illumination from the Sun at all. This eclipse is a member of Saros series 141. The position of the Moon at the moment of greatest eclipse is as follows: Object Right Ascension Declination Constellation Angular Size The Moon 14h47m 17°11'S Libra 31'24" |
