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". 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"; Lunar eclipse#Blood moon, blood refers to the typical red color of the Moon during a total lunar eclipse. This was the last total lunar eclipse until May 2021 lunar eclipse, 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. The impact was observed during totality, at 4:41 UTC, on the left side of the Moon. It is the only documented case of a lunar impact during a total lunar eclipse.

Visibility

The eclipse was visible in its entirety from North and South America, as well as portions of western Europe and Maghreb, 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.

Timing

The penumbral phases of the eclipse changes the appearance of the Moon only slightly and is generally not noticeable.

Impact sighted

Live streaming, 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." Originally thinking it was Noise (electronics), electronic noise from the camera, astronomers and Citizen science, citizen scientists shared the visual phenomenon with each other to identify it. 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. The location of the impact may be somewhere in the lunar highlands, south of Byrgius (crater), Byrgius crater, according to Justin Cowart, a graduate student in geosciences at Stony Brook University in New York (state), New York who first saw the flash of light. “A meteoroid about this size hits the moon about once a week or so,” said Cowart. This may be the first time that a collision, during a total lunar eclipse, was captured on video. “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, London, Natural History Museum in London. People posted their images and video of a flicker of light as news spread quickly on social media. 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. “Something inside of me told me that this time would be the time,” said Madiedo. 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 (crater)#Satellite craters, Lagrange H, K and X craters". Other astronomers estimated a 10-15 meter crater from a 45 kg asteroid moving 61,000 km/h.

Lunar year series

Saros series

It is part of Saros cycle 134.

Half-Saros cycle

A lunar eclipse will be preceded and followed by solar eclipses by 9 years and 5.5 days (a Saros (astronomy)#Relationship between lunar and solar saros .28sar.29, half saros).Mathematical Astronomy Morsels, Jean Meeus, p.110, Chapter 18, ''The half-saros'' This lunar eclipse is related to two annular solar eclipses of Solar Saros 141.
