Penumbral eclipse — 30 October 2031
NASA’s broad visibility summary is: Americas. This does not establish visibility from a particular address or local horizon.
What the fields mean
- Greatest eclipse is the instant when the distance between Earth’s umbral-shadow axis and the Moon’s center is smallest; NASA’s decade table labels this time TD.
- Umbral magnitude is the fraction of the Moon’s diameter immersed in Earth’s umbral shadow. It is negative for penumbral eclipses, between zero and one for partial eclipses, and at least one for total eclipses.
- Saros identifies the repeating eclipse series. It is not a visibility or brightness score.
- Duration is the partial-phase duration for a partial eclipse. For a total eclipse, NASA lists both the partial-phase span and the shorter interval of totality.

FAQ
How many lunar eclipses are there in 2031?
There are 3 lunar eclipses in 2031: 3 penumbral.
When are the lunar eclipses in 2031?
7 May 2031 (penumbral); 5 June 2031 (penumbral); 30 October 2031 (penumbral).
Is every 2031 lunar eclipse visible worldwide?
No. Visibility depends on whether the Moon is above the horizon at the observing location. The regions on this page are broad NASA summaries; use the linked NASA diagram and a location-specific source for local circumstances.
