APOD: Penumbral Eclipse Rising (2017 Feb 18)

Image Penumbral Eclipse Rising

Explanation: As seen from Cocoa Beach Pier, Florida, planet Earth, the Moon rose at sunset on February 10 while gliding through Earth's faint outer shadow. In progress was the first eclipse of 2017, a penumbral lunar eclipse followed in this digital stack of seaside exposures. Of course, the penumbral shadow is lighter than the planet's umbral shadow. That central, dark, shadow is easily seen on the lunar disk during a total or partial lunar eclipse. Still, in this penumbral eclipse the limb of the Moon grows just perceptibly darker as it rises above the eastern horizon. The second eclipse of 2017 could be more dramatic though. With viewing from a path across planet Earth's southern hemisphere, on February 26 there will be an annular eclipse of the Sun.

Probably rising above the eastern horizon.

Yes, an annular eclipse of the Sun is more exciting than a penumbral eclipse of the Moon. Yawn!

Unless it's an alternative moonrise.

Unless it's happening in a hemisphere where you don't happen to live.
