A penumbral lunar eclipse will occur at the Moon’s descending node of orbit on Sunday, December 20, 2048,[1] with an umbral magnitude of −0.1420.

A penumbral lunar eclipse occurs when part or all of the Moon's near side passes into the Earth's penumbra.

Occurring only about 13 hours before apogee (on December 20, 2048, at 19:30 UTC), the Moon's apparent diameter will be smaller.

Because it occurs on the same calendar date, the Earth's shadow will be in nearly the same location relative to the background stars.

This eclipse is a part of Saros series 145, repeating every 18 years, 11 days, and containing 71 events.
