A total lunar eclipse will occur at the Moon’s ascending node of orbit on Sunday, February 22, 2054,[1] with an umbral magnitude of 1.2781. A lunar eclipse occurs when the Moon moves into the Earth's shadow, causing the Moon to be darkened. A total lunar eclipse occurs when the Moon's near side entirely passes into the Earth's umbral shadow. Unlike a solar eclipse, which can only be viewed from a relatively small area of the world, a lunar eclipse may be viewed from anywhere on the night side of Earth. A total lunar eclipse can last up to nearly two hours, while a total solar eclipse lasts only a few minutes at any given place, because the Moon's shadow is smaller. Occurring about 1.2 days before perigee (on February 21, 2054, at 2:55 UTC), the Moon's apparent diameter will be larger.[2]
This lunar eclipse will be the first of an almost tetrad, with the others being on August 18, 2054 (total); February 11, 2055 (total); and August 7, 2055 (partial).
Visibility
[edit | edit source]The eclipse will be completely visible over North and South America, seen rising over much of Africa and Europe and setting over northeast Asia and eastern Australia.[3]

Eclipse details
[edit | edit source]Shown below is a table displaying details about this particular solar eclipse. It describes various parameters pertaining to this eclipse.[4]
| Parameter | Value |
|---|---|
| Penumbral Magnitude | 2.25022 |
| Umbral Magnitude | 1.27805 |
| Gamma | −0.32419 |
| Sun Right Ascension | 22h23m02.4s |

| Sun Semi-Diameter | 16'10.2" |
| Sun Equatorial Horizontal Parallax | 08.9" |
| Moon Right Ascension | 10h22m40.9s |
| Moon Declination | +09°46'14.8" |
| Moon Semi-Diameter | 16'38.0" |

| ΔT | 87.8 s |
Eclipse season
[edit | edit source]This eclipse is part of an eclipse season, a period, roughly every six months, when eclipses occur. Only two (or occasionally three) eclipse seasons occur each year, and each season lasts about 35 days and repeats just short of six months (173 days) later; thus two full eclipse seasons always occur each year. Either two or three eclipses happen each eclipse season. In the sequence below, each eclipse is separated by a fortnight.

Lunar eclipses of 2053–2056
[edit | edit source]This eclipse is a member of a semester series. An eclipse in a semester series of lunar eclipses repeats approximately every 177 days and 4 hours (a semester) at alternating nodes of the Moon's orbit.[5]
The penumbral lunar eclipses on June 27, 2056 and December 22, 2056 occur in the next lunar year eclipse set.
Saros 124
[edit | edit source]This eclipse is a part of Saros series 124, repeating every 18 years, 11 days, and containing 73 events. The series started with a penumbral lunar eclipse on August 17, 1152. It contains partial eclipses from March 21, 1513 through June 15, 1639; total eclipses from June 25, 1657 through April 18, 2144; and a second set of partial eclipses from April 29, 2162 through July 14, 2288. The series ends at member 73 as a penumbral eclipse on October 21, 2450.
The longest duration of totality was produced by member 39 at 101 minutes, 27 seconds on August 30, 1765. All eclipses in this series occur at the Moon’s ascending node of orbit.[6]

Eclipses are tabulated in three columns; every third eclipse in the same column is one exeligmos apart, so they all cast shadows over approximately the same parts of the Earth.
Tritos series
[edit | edit source]This eclipse is a part of a tritos cycle, repeating at alternating nodes every 135 synodic months (≈ 3986.63 days, or 11 years minus 1 month). Their appearance and longitude are irregular due to a lack of synchronization with the anomalistic month (period of perigee), but groupings of 3 tritos cycles (≈ 33 years minus 3 months) come close (≈ 434.044 anomalistic months), so eclipses are similar in these groupings.
Inex series
[edit | edit source]This eclipse is a part of the long period inex cycle, repeating at alternating nodes, every 358 synodic months (≈ 10,571.95 days, or 29 years minus 20 days). Their appearance and longitude are irregular due to a lack of synchronization with the anomalistic month (period of perigee). However, groupings of 3 inex cycles (≈ 87 years minus 2 months) comes close (≈ 1,151.02 anomalistic months), so eclipses are similar in these groupings.
