Penumbral lunar eclipse March 24-25, 2024 Posted by Marcy Curran March 20, 2024 Penumbral lunar eclipse People in Japan, the eastern half of Australia, the Americas, the western half of Africa, western Europe – and several oceans and parts of Antarctica – will see a deep penumbral lunar eclipse on March 24-25, 2024. This eclipse begins the eclipse season during which we’ll also have the April 8, 2024, total eclipse of the sun … shortly due to be seen by millions in North America. Please help EarthSky keep going! Our annual crowd-funder is going on now. PLEASE DONATE today to continue enjoying updates on your cosmos and world. Penumbral eclipse begins at 4:53 UTC on March 25, 2024. That is 11:53 p.m. CDT on March 24 in North America. Greatest eclipse is at 7:12 UTC on March 25 (2:12 a.m. CDT) with a penumbral magnitude of 0.9577. In other words, at greatest eclipse, nearly all of the moon will be inside the Earth’s outer penumbral shadow. The moon will never go into Earth’s darker umbral shadow. So it will never seem as if a dark bite has been taken out of the moon. Instead, it’ll be a subtle darkened shading on the moon, and, at mid-eclipse, only a small sliver of the moon will fall outside this dark shading. Penumbral eclipse ends at 9:33 UTC on March 25 (4:33 a.m. CDT). Duration of eclipse: This is a deep penumbral lunar eclipse with a duration of 279.9 minutes. Note: A penumbral lunar eclipse is the most subtle kind of lunar eclipse, one that most people won’t even notice. Some people say the moon’s shadow won’t be detected until the disk of the moon is immersed in about 2/3 of the penumbral shadow. On the other hand, others notice it right away. It depends on how observant they are, atmospheric conditions and a person’s visual acuity. The full moon and eclipses If this full moon were truly opposite the sun, there’d be a total umbral eclipse of the moon. That is, the darkest part of Earth’s shadow – the umbra – would cover the moon at mid-eclipse. But this full moon in March sweeps to the north of the Earth’s umbra. So no total or partial lunar eclipse in the Earth’s dark shadow can take place. Instead, the full moon almost fully passes through the Earth’s penumbral shadow. So it’s a very deep penumbral eclipse. At no time will Earth’s dark shadow take a “bite” out of the moon. Instead, penumbral eclipses are all about subtle shadings. The March 25 penumbral lunar eclipse occurs when the moon is in the constellation of Virgo the Maiden. Find the moon’s path with respect to Earth’s penumbral shadows below.  A map for the penumbral lunar eclipse on March 25, 2024. It sweeps across parts of Antarctica, the western half of Africa, western Europe, the Atlantic Ocean, the Americas, the Pacific Ocean, Japan, and the eastern half of Australia. Areas in white on the map will see the total penumbral eclipse. The line down the middle notes where greatest eclipse occurs. Shaded areas will see part of the eclipse and dark areas are where the eclipse is not visible. Note the difference between UTC and TDT (terrestrial dynamical time, often abbreviated TT as well).

Eclipses in 2024] The March 24-25, 2024, penumbral lunar eclipse is followed two weeks later by a total solar eclipse on April 8, 2024. In fact, these two eclipses take place within a single eclipse season. An eclipse season is an approximate 35-day period during which it’s inevitable for at least two (and possibly three) eclipses to take place. Then later this year, the September-October 2024 eclipse season will feature a very shallow partial lunar eclipse on September 17-18, 2024, and an annular solar eclipse on October 2, 2024.

Full Moon This event is visible to the naked eye from Austin. MON, 25 MAR 2024 AT 02:00 CDT (07:00 UTC) The Moon will reach full phase. At this time of the month, it is visible for much of the night, rising at around dusk and setting at around dawn. The Worm Moon The sequence of full moons that fall through the year are sometimes assigned names such as the "Worm Moon", according to the months and seasons in which they fall. This practice has been popularized in recent decades by the Farmers' Almanac in the United States. The names used by that almanac claim to have ancient origins from Native American tribes. This claim has been examined in detail by Patricia Haddock's book Mysteries of the Moon (1992) and is partially true, but the selection of names is largely arbitrary. Throughout history a great variety of different names have been given to the sequence of lunar cycles through the year, and modern lists of such names, such as those popularised by the Farmers' Almanac, tend to inevitably be a medley of names taken from many different cultures. According to the Venerable Bede's De temporum ratione (The Reckoning of Time; 725 AD) – an authoritative account of the calendar used in Saxon England – the lunar month containing the first full moon after the March equinox (within spring) was called the "Easter month (Easter-mōnaþ)". The biography of Charlemagne (circa 817–833 AD), written a few years after his death, gives a name of the "also the Easter month (Ōstar-mānod)" for the same lunar month. However, in the scheme followed by the Farmers' Almanac, which has become rather widely quoted, any full moon in the month of March is called the "Worm" Moon. --Observing the Moon in coming days-- Over the nights following 25 March, the Moon will rise around an hour later each day, becoming prominent later in the night. Within a few days, it will only be visible in the pre-dawn and early-morning sky. By the time it reaches last quarter, a week after full moon, it will rise in the middle of the night and set at around noon. The table below lists the rising and setting times of the moon in the days around full moon: (see link) --The exact moment of full moon-- The exact moment of full moon is defined as the time when the Moon's ecliptic longitude is exactly 180° away from the Sun's ecliptic longitude, as observed from the center of the Earth. However, the Moon does not appear in any way special at this instant in time, and a full moon can be observed at any time of night. At the moment it reaches full phase, the Moon will lie at a declination of 1°01'S in the constellation Virgo . It will lie at a distance of 405,000 km from the Earth. The chart below shows the size of this month's full moon in comparison to the largest (perigee) and smallest (apogee) possible apparent size of a full moon, drawn to scale. (scale is at link) The celestial coordinates of the Moon at the time it reaches full phase will be: Object Right Ascension Declination Constellation Angular Size The Moon 12h19m00s 1°01'S Virgo 29'27" The coordinates above are given in J2000.0. |
