"Penumbral" Eclipse
Hopefully you have a telescope on hand, or eagle-eye vision, because the "penumbral" lunar eclipse isn't as noticeable as a total lunar eclipse. The subtle phenomenon occurs when the moon moves through the outer part of the Earth's shadow (check out the photo below from Sky & Telescope Magazine). This outer shadow of the Earth blocks part of the sun's rays from reaching the moon, making it appear slightly darker than normal.
The eclipse will be visible from Europe, Africa, western Asia and eastern North and South America around 7:43 p.m. Friday night.
