astronomical event

annular solar eclipse

A total lunar eclipse occurred at the Moon's descending node of orbit on Tuesday, March 3, 2026, with an umbral magnitude of 1.1507. 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. The Moon's apparent diameter was near the average, as it occurred 6.7 days after perigee and 6.9 days before apogee.
