January 2046 lunar eclipse
A partial lunar eclipse will occur at the Moon’s descending node of orbit on Monday, January 22, 2046, with an umbral magnitude of 0.0550. A lunar eclipse occurs when the Moon moves into the Earth's shadow, causing the Moon to be darkened. A partial lunar eclipse occurs when one part of the Moon is in the Earth's umbra, while the other part is in the Earth's penumbra. 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. Occurring about 1.1 days before perigee, the Moon's apparent diameter will be larger.
Visibility
The eclipse will be completely visible over Australia, east and north Asia, and northwestern North America, seen rising over eastern Europe and west, central, and south Asia and setting over much of North America.Eclipse details

Eclipse season
This eclipse is part of an eclipse season, a period, roughly every six months, when eclipses occur. Only two eclipse seasons occur each year, and each season lasts about 35 days and repeats just short of six months 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.| January 22 Descending node | February 5 Ascending node |
| Partial lunar eclipse Lunar Saros 115 | Annular solar eclipse Solar Saros 141 |
