Tonight's lunar eclipse is a deep partial lunar eclipse, meaning it falls just short of being total. At the moment of greatest eclipse, about 96% of the Moon will be immersed in Earth's dark umbral shadow, making it appear almost completely eclipsed. The event is visible across Africa, Europe, most of the Americas, and the eastern Pacific region, provided the Moon is above the horizon and the sky is dark at the time. The entire eclipse lasts about 5 hours and 39 minutes, with the partial phase lasting more than 3 hours.

Observers won't need any special equipment; the eclipse is safe to view with the naked eye, although binoculars or a telescope can enhance the experience. As Earth's shadow moves across the Moon, it will first appear as a dark "bite" taken from its edge. Near maximum eclipse, the shadowed portion may take on a reddish hue, caused by sunlight filtering through Earth's atmosphere and bending onto the Moon. Because a small sliver of the Moon remains outside the shadow, viewers should also see a bright white patch along one edge, creating a dramatic contrast during the peak of the event.
While clouds are expected over Maryland and the surrounding area, lucky observers may still catch a quick view of the eclipse through occasional clear patches. Read the full article at: EarthSky
