Lunar Eclipse Later This Month

May 16, 2013; 8:12 AM ET

An eclipse of the moon will occur later this month, on May 25. This eclipse will be a penumbral eclipse visible across much of the Americas and Africa. According to Space.com, a penumbral eclipse is defined as "This is the least interesting type of eclipse, because the moon is in Earth's faint outer (penumbral) shadow. Unless you're a seasoned skywatcher, you likely won't notice the effect."

So, later this month, it will not be an outstanding show, but if you know what to look for, it will be interesting. Here is a map of where it may be visible:

To see this penumbral eclipse, you have to really pay attention. At no point will the Moon be more than partially eclipsed, meaning that while we will see a reduction in the Moon's brightness, no part of its disk will be completely within the shadow (umbra) and no part of its disk will appear completely dark.

The apparent dimming of the Moon's disk in penumbral eclipses is, at best, barely perceptible to the untrained eye.

The Eclipse Begins: 03:53:11 UT (11:53 PM EDT) May 24

The Greatest Eclipse Will Be: 04:10:00 UT (12:10 AM EDT) May 25

The Eclipse Ends: 04:26:56 UT (12:26 AM EDT) May 25
