Also, a blood moon requires less totality than a solar eclipse and can be seen from anywhere in the world where it's nighttime. Instead of the moon blocking the sun from the Earth for a very short period (a solar eclipse), the Earth is casting a shadow on the moon. While not as rare as a solar eclipse, a lunar eclipse is still a significant astronomical event. How are lunar and solar eclipses different? The term Blood Moon once was used in some sects of Christian prophecy to describe a total lunar eclipse that belonged to a tetrad of total lunar eclipses. As a result, this shadow often appears as a deep orange or copper color, hence the "bloody" moniker and why some refer to it as a "red moon." Any time this rare alignment occurs, the moon is also full. Any sunlight that makes it to the moon's surface during the eclipse passes through the Earth's atmosphere first, NASA says. So if this lunar occurrence isn't connected to our blood-sucking friends or even near Halloween, what is a blood moon exactly? What causes a blood moon?Īnother name for a total lunar eclipse, a blood moon happens when the Earth is exactly between the sun and the moon, with the Earth casting its shadow on the moon. And you might think because there is such a thing as a "blood moon" that something sinister is going on, but there’s no need to be packing garlic or a crucifix when you see the next blood moon, which will take place in March 2025. seems like they are both intoxicated by the moonlight. There are two large cities on the path of totality: Edmonton and Calgary in Alberta, Canada.Werewolves, vampires. Where to see the August 2044 total solar eclipseĪlthough the date of the eclipse based on UTC time is August 23, 2044, totality will take place on the evening of August 22, local time. The final solar eclipse in the sequence is a much bigger event: totality will be visible along a path that begins in Greenland, crosses northern and western Canada, and ends around sunset in Montana, North Dakota, and South Dakota. The February 2044 solar eclipse is a central eclipse with no southern limit: although the center of the Moon's shadow strikes Earth, part of the antumbra misses Earth.) (In technical language, the 2043 solar eclipses are called non-central eclipses, because the center of the Moon's shadow misses Earth. The first three solar eclipses in the 2043-2044 “super tetrad” are small: the Moon's dark umbral or antumbral shadow only just grazes Earth. Three Small Solar Eclipses, and a Big One February 28, 2044: Annular solar eclipse.September 19, 2043: Total lunar eclipse.The dates for the 2043-2044 occurrence are as follows. In other words, it is a series of eight full eclipses in a row-no partials or penumbrals-over a period of about 18 months.Ī “super tetrad” is extremely rare. “Super Tetrads”: 4 Total Lunar + 4 Total/Annular Solar EclipsesĪt, we have given the name “super tetrad” to another phenomenon: four consecutive eclipse seasons that each contain a total lunar eclipse plus a total or annular solar eclipse. The magnitude of the partial eclipse was 0.97-although this was a fraction short of being total, it looked very similar to a total eclipse, and the Moon acquired a noticeably reddish tint. There was almost a tetrad in 2021-2022, with total lunar eclipses on May 26, 2021, May 16, 2022, and November 8, 2022, and a big partial lunar eclipse on November 19, 2021. The last tetrad took place in 2014-2015 the next will happen in 2032-2033. This is followed by a period of roughly 300 years where a tetrad occurs every 15 years or so.Īt the moment, we are about halfway through the second half of this cycle. For about 300 years, there are no tetrads at all. Tetrads are not particularly rare, although they come in interesting cycles of around 600 years. The conjunction with a total lunar eclipse has led to the popular term 'Beaver blood moon' in the United States. The term comes from the Greek word tetras, which means a group of four. In other words, it is four “ Blood Moons” in a row, about six months apart. Tetrads: 4 Total Lunar EclipsesĪ tetrad is a phenomenon where four consecutive eclipse seasons each contain a total lunar eclipse. Here's everything you need to know about the event. The nature of each eclipse depends on the alignment of the Earth, Moon, and Sun, as well as the distances between them. A Blood Moon total lunar eclipse will occur on May 15-16, 2022 and will look similar to this view of one from July 2018. ![]() The lunar eclipse can be total, partial, or penumbral the solar eclipse can be total, annular, hybrid, or partial. Generally speaking, each season contains a pair of eclipses: a lunar eclipse at Full Moon, and a solar eclipse at New Moon. In 2021-2022, there was almost-but not quite-a tetrad.Įvery six months or so, there is an eclipse season. Business Date to Date (exclude holidays).
