Phase 2: "Moon enters umbra" marks the beginning of the partial eclipse. The penumbral shading gradually becomes more evident as the moon moves deeper in. Watch for a slight darkening to become apparent on the moon's celestial southeast (lower left) side. But the shadow is so weak that most people won't see anything of the penumbra until about 70% of the moon's diameter is inside of it. Phase 1: "Moon enters penumbra" is when the moon's leading edge enters the pale outer fringe of Earth's shadow: the penumbra. This eclipse will occur in five phases, with different things to watch for at each. (Image credit: NASA's Scientific Visualization Studio) This diagram shows the stages of the partial lunar eclipse on Nov. That's why it will seem to move at an almost "leisurely pace" through the Earth's shadow, taking over 100 minutes from the time of first umbral contact to the time of greatest eclipse, and vice versa (greatest eclipse to last umbral contact). 20, it will also be moving at its slowest speed in its orbit. 18.īecause the moon will arrive at apogee - the farthest point in its orbit from Earth - on Nov. *Times listed with an asterisk denote times prior to midnight the corresponding calendar date is Nov.

If you're in Hawaii, the eclipse happens deep in the night and nearly overhead. Skywatchers farther east will find the moon sinking lower toward the west around mid-eclipse. The Mercator map shows that those near the West Coast will see the maximum phase of the eclipse happen high in a dark sky long before sunrise. As it moves in its orbit around the Earth, the moon moves from west to east (right to left) through the Earth's shadow. But as you can see from the diagram, it's really the moon that is doing the creeping. As you watch the progress of the eclipse it appears that the Earth's shadow is creeping across the moon's face. Studying the diagram and map courtesy of Fred Espenak's, along with our timetable, tells what to expect at your location and when. If skies are not clear and you miss out, you will have to wait a while for the next total lunar eclipse.A map showing the visibility of the partial lunar eclipse on Nov. ![]() will see a partial eclipse for about an hour beginning around 4:45 a.m. The totality of the lunar eclipse will be about 14 minutes long near Los Angeles from about 4:11 a.m. This eclipse will be very special for the West Coast of the U.S., where they will see a total lunar eclipse. This happens when the full moon is closest to the earth, so it appears larger.Īnother reason we may get some great photos from this event: When the Earth casts a shadow on the moon, it can look darker and even red, so it's also called a Blood Moon. This eclipse may be even more incredible because the full moon will be a super moon. ![]() On May 26, 2021, most of the United States will see some or all of a total lunar eclipse.Ī total lunar eclipse happens when Earth lines up between the sun and the moon.
