A total lunar eclipse occurred on 21 January 2019 UTC (Coordinated Universal Time). For observers in the Americas, the eclipse took place between the evening of Sunday, 20 January and the early morning hours of Monday, 21 January. For observers in Europe and Africa, the eclipse occurred during the morning of 21 January. The Moon was near its perigee on 21 January and as such can be described as a "supermoon". [1]
As this supermoon was also a wolf moon (the first full moon in a calendar year), it was referred to as a "super blood wolf moon"; blood refers to the typical red color of the Moon during a total lunar eclipse. [2] This was the last total lunar eclipse until May 2021. This was a Super Full Moon because occurred less than a day before perigee and the Moon was less than exactly 360,000 km (223,694 mi).
The Griffith Observatory in Los Angeles, California captured video showing a meteor between the size of an acorn and tennis ball impacting the Moon during the eclipse. [3] The impact was observed during totality, at 4:41 UTC, on the left side of the Moon. [4] It is the only documented case of a lunar impact during a total lunar eclipse. [5] [6]
The eclipse was visible in its entirety from North and South America, as well as portions of western Europe and northwest Africa. From locations in North America, the eclipse began during the evening hours of January 20. Observers at locations in Europe and much of Africa were able to view part of the eclipse before the Moon set in the early morning (pre-dawn) hours of January 21.

It took place in the constellation of Cancer, just west of the Beehive Cluster.
Livestreams detected a flash of light while viewing the eclipse. It was "likely caused by the crash of a tiny, fast-moving meteoroid left behind by a comet." [5]
Originally thinking it was electronic noise from the camera, astronomers and citizen scientists shared the visual phenomenon with each other to identify it. [5]
When totality was just beginning at 4:41 UT, the tiny speck of light blinked south of a nearly 55-mile-wide crater in the western part of the moon. [9]
The location of the impact may be somewhere in the lunar highlands, south of Byrgius crater, according to Justin Cowart, a graduate student in geosciences at Stony Brook University in New York who first saw the flash of light. [5]
“A meteoroid about this size hits the moon about once a week or so,” said Cowart. [9]
This may be the first time that a collision, during a total lunar eclipse, was captured on video. [5]
“I have not heard of anyone seeing an impact like this during a lunar eclipse before,” said Sara Russell, a professor of planetary sciences at the Natural History Museum in London. [5]
People posted their images and video of a flicker of light as news spread quickly on social media. [9]
Working overtime, co-director of the Moon Impacts Detection and Analysis System, MIDAS, an astrophysicist at the University of Huelva in Spain, Jose Maria Madiedo, set up eight telescopes to watch for any impacts during the eclipse. [9]
“Something inside of me told me that this time would be the time,” said Madiedo. [9]
A paper calculated a mass between 20 and 100 kilograms and diameter of 30 to 50 cm that may have caused a 7–15 meter crater located "inside a triangle with vertices in the Lagrange H, K and X craters". [10] Other astronomers estimated a 10-15 meter crater from a 45 kg asteroid moving 61,000 km/h. [11]

A total lunar eclipse took place on 3 March 2007, the first of two eclipses in 2007. The Moon entered the penumbral shadow at 20:18 UTC, and the umbral shadow at 21:30 UTC. The total phase lasted between 22:44 UTC and 23:58 UTC with a distinctive brick-red shade. The Moon left the umbra shadow at 01:11 UTC and left the penumbra shadow at 02:24 UTC 2007-03-04. The second lunar eclipse of 2007 occurred on 28 August.
A total lunar eclipse occurred on February 20 and February 21, 2008. It was visible in the eastern evening sky on February 20 for all of North and South America, and on February 21 in the predawn western sky from most of Africa and Europe. Greatest Eclipse occurring on Thursday, February 21, 2008, at 03:26:03 UTC, totality lasting 49 minutes and 45.6 seconds.
A partial lunar eclipse took place on 16 August 2008, the second of two lunar eclipses in 2008, with the first being a total eclipse on 20 February 2008. The next lunar eclipse was a penumbral eclipse occurring on 9 February 2009, while the next total lunar eclipse occurred on 21 December 2010.
A total solar eclipse occurred at the Moon's descending node of the orbit on August 1, 2008. A solar eclipse occurs when the Moon passes between Earth and the Sun, thereby totally or partly obscuring the image of the Sun for a viewer on Earth. A total solar eclipse occurs when the Moon's apparent diameter is larger than the Sun's, blocking all direct sunlight, turning day into darkness. Totality occurs in a narrow path across Earth's surface, with the partial solar eclipse visible over a surrounding region thousands of kilometres wide. It had a magnitude of 1.0394 that was visible from a narrow corridor through northern Canada (Nunavut), Greenland, central Russia, eastern Kazakhstan, western Mongolia and China. Occurring north of the arctic circle, it belonged to the so-called midnight sun eclipses. The largest city in the path of the eclipse was Novosibirsk in Russia. Occurring only 2.5 days after perigee, the Moon's apparent diameter was larger than average.
A total lunar eclipse took place on 4 April 2015. It is the former of two total lunar eclipses in 2015, and the third in a tetrad. Other eclipses in the tetrad are those of 15 April 2014, 8 October 2014, and 28 September 2015.
A total lunar eclipse took place between 27 and 28 September 2015. It was seen on Sunday evening, 27 September, in the Americas; while in Europe, Africa, and the Middle East, it was seen in the early hours of Monday morning, 28 September. It was the latter of two total lunar eclipses in 2015, and the final in a tetrad. Other eclipses in the tetrad are those of 15 April 2014, 8 October 2014, and 4 April 2015.
A penumbral lunar eclipse took place on Tuesday, January 20, 1981, the first of two lunar eclipses in 1981. In a rare total penumbral eclipse, the entire Moon was partially shaded by the Earth, and the shading across the Moon should have been quite visible at maximum eclipse. The penumbral phase lasted for 4 hours and 24 minutes in all, though for most of it, the eclipse was extremely difficult or impossible to see. The moon's apparent diameter was larger because the eclipse occurred 5.2 days after perigee.
A total lunar eclipse occurred on 31 January 2018. The Moon was near its perigee on 30 January and as such may be described as a "supermoon", when the Moon's distance from the Earth is less than 360,000 km. The previous supermoon lunar eclipse was in September 2015.
A total lunar eclipse took place on Saturday, April 13, 1968, the first of two total eclipses in 1968, the second being on October 6, 1968.
A partial lunar eclipse took place on Monday, August 17, 1970, the second of two lunar eclipses in 1970, the first was on February 21 of that year. The Earth's shadow on the Moon was clearly visible in this eclipse, with 41% of the Moon in shadow; the partial eclipse lasted for 2 hours and 11 minutes. It was the second of two lunar eclipses in 1970.
A total solar eclipse took place on 13–14 November 2012 (UTC). Because it crossed the International Date Line it began in local time on November 14 west of the date line over northern Australia, and ended in local time on November 13 east of the date line near the west coast of South America. Its greatest magnitude was 1.0500, occurring only 12 hours before perigee, with greatest eclipse totality lasting just over four minutes. A solar eclipse occurs when the Moon passes between Earth and the Sun, thereby totally or partly obscuring the image of the Sun for a viewer on Earth. A total solar eclipse occurs when the Moon's apparent diameter is larger than the Sun's, blocking all direct sunlight, turning day into darkness. Totality occurs in a narrow path across Earth's surface, with the partial solar eclipse visible over a surrounding region thousands of kilometres wide.
An annular solar eclipse occurred on September 1, 2016. A solar eclipse occurs when the Moon passes between Earth and the Sun, thereby totally or partly obscuring the image of the Sun for a viewer on Earth. An annular solar eclipse occurs when the Moon's apparent diameter is smaller than the Sun's, blocking most of the Sun's light and causing the Sun to look like an annulus (ring). An annular eclipse appears as a partial eclipse over a region of the Earth thousands of kilometres wide. In this case, annularity was observed in Gabon, Congo, Democratic Republic of the Congo, Tanzania, Mozambique, Madagascar, and Reunion.
An annular solar eclipse took place on February 26, 2017. A solar eclipse occurs when the Moon passes between Earth and the Sun, thereby totally or partly obscuring the image of the Sun for a viewer on Earth. An annular solar eclipse occurs when the Moon's apparent diameter is smaller than the Sun's, blocking most of the Sun's light and causing the Sun to look like an annulus (ring). An annular eclipse appears as a partial eclipse over a region of the Earth thousands of kilometres wide. Occurring only 4.7 days before perigee, the Moon's apparent diameter was larger. The moon's apparent diameter was just over 0.7% smaller than the Sun's.
An annular solar eclipse occurred on December 14, 1955. A solar eclipse occurs when the Moon passes between Earth and the Sun, thereby totally or partly obscuring the image of the Sun for a viewer on Earth. An annular solar eclipse occurs when the Moon's apparent diameter is smaller than the Sun's, blocking most of the Sun's light and causing the Sun to look like an annulus (ring). An annular eclipse appears as a partial eclipse over a region of the Earth thousands of kilometres wide.
An annular solar eclipse occurred at the Moon's descending node of the orbit on February 4–5, 1981. A solar eclipse occurs when the Moon passes between Earth and the Sun, thereby totally or partly obscuring the image of the Sun for a viewer on Earth. An annular solar eclipse occurs when the Moon's apparent diameter is smaller than the Sun's, blocking most of the Sun's light and causing the Sun to look like an annulus (ring). An annular eclipse appears as a partial eclipse over a region of the Earth thousands of kilometres wide. This annular solar eclipse was large because the Moon covered 99.4% of the Sun, with a path width of only 25 km . It was visible in Australia, crossing over Tasmania and southern Stewart Island of New Zealand near sunrise on February 5 (Thursday), and ended at sunset over western South America on February 4 (Wednesday). Occurring only 4 days before perigee, the moon's apparent diameter was larger.
