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, January 20 and the early morning hours of Monday, January 21. For observers in Europe and Africa, the eclipse occurred during the morning of January 21. The Moon was near its perigee on January 21 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.


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 was able to view part of the eclipse before the Moon sets in the early morning (pre-dawn) hours of January 21.

Contact points relative to Earth's umbral and penumbral shadows, here with the Moon near its descending node

The timing of total lunar eclipses are determined by its contacts:[3]

P1 (First contact): Beginning of the penumbral eclipse. Earth's penumbra touches the Moon's outer limb.
U1 (Second contact): Beginning of the partial eclipse. Earth's umbra touches the Moon's outer limb.
U2 (Third contact): Beginning of the total eclipse. The Moon's surface is entirely within Earth's umbra.
Greatest eclipse: The peak stage of the total eclipse. The Moon is at its closest to the center of Earth's umbra.
U3 (Fourth contact): End of the total eclipse. The Moon's outer limb exits Earth's umbra.
U4 (Fifth contact): End of the partial eclipse. Earth's umbra leaves the Moon's surface.
P4 (Sixth contact): End of the penumbral eclipse. Earth's penumbra no longer makes contact with the Moon.

The penumbral phases of the eclipse changes the appearance of the Moon only slightly and is generally not noticeable.[4]
