(WDEF) Amy-O-Meter: Penumbral Lunar Eclipse
Sky watchers get the chance to see a partial lunar eclipse Friday night.
A "penumbral lunar eclipse" happens when the moon slips into the Earth's outer shadow or penumbra.
The moon will be in partial shadow for a total of four hours, with the peak occurring at 7:50pm EDT. At that point, about 76% of the moon will be in shadow.
A penumbral lunar eclipse may be difficult for the casual observer to see. Look for a gradual shading of the moon.
If you can't get outside to view the eclipse yourself, check out space.com. The website will offer a live webcast
from the online Slooh Space Camera. The space cam broadcast team will join the broadcast at 7:30pm EDT to provide commentary for the celestial event.
