Penumbral Lunar EclipseWhen: Fri Oct 18, 2013 3PM-7PM PT |
The full moon will dip into Earth's shadow tonight October 18th, producing a lunar eclipse that can be seen by keen observers.
With tonights perfect weather, skywatchers will get the chance to observe part of the southern portion of the moon passing into Earth's penumbra — the planet's outer shadow.
The shading will be subtle, but during the penumbral lunar eclipse, the moon will be partially in shadow for about four hours with the time of deepest eclipse occurring at 7:50PM EDT (4:50PM PT). At that moment, the Earth's outer shadow will cover 76.5 percent of the lunar disk.
