Full moons and eclipses and comets – Oh my!

Tomorrow evening, February 10, the full moon will look a little odd when it rises in the eastern sky beginning at approximately 5:35pm. That’s because it will already be in eclipse as it rises. More specifically it will be in a penumbral eclipse, which is is a lunar eclipse that occurs when the moon becomes completely immersed in the penumbral cone of the Earth without touching the umbra.

Penumbral eclipses can be difficult to see from Earth because the moon is merely passing through the Earth’s penumbral shadow, causing only subtle shading on the moon’s surface.

Maximum eclipse will occur just after sunset, at 5:45pm. Observers will see the penumbral shadow moving across the moon as the eclipse progresses to it conclusion at 7:53pm.

But, wait…there’s more!

Comet 45P/Honda-Mrkos-Pajdušáková, will sweep closest to Earth tomorrow night at around 8:30pm, at which time the comet will be 7.4 million miles away. The greenish comet will be visible by telescope and binoculars, but not to the naked eye.

Slooh will be live streaming both events starting at 3:30pm MST.
