At maximum eclipse, the moon could appear nearly 10,000 times dimmer than before the eclipse began. But as the moon becomes more and more diminished, you'll begin seeing more and more of the fainter stars. Before the eclipse began, the sky was bright the moon acting like a spotlight obliterating all but the brightest stars.

With a telescope, watch as the umbra's edge engulfs various lunar features such as craters, mountains and valleys.Īnd as the moon wanes to a crescent, be sure to take a look around the sky. This will be a much more obvious and dramatic sight as the moon's leading-edge slips into the umbra, where no direct sunlight reaches. 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. Local circumstances for the partial lunar eclipse on 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.
