On the U.S. east coast, the eclipse will start on Saturday, December 10, about 7:01 a.m. EST and it will reach full eclipse at 7:32 a.m. EST, and last about 51 minutes total.

This lunar eclipse is rare because we will also have a chance to observe a phenomena called selenelion or selenehelion. Selenelion is the term for the phenomena when both the Sun and the eclipsed Moon can be observed at the same time. Obviously, this happens only when lunar eclipse occurs just before sunset or just after sunrise. At that case, both bodies appear just above the horizon at nearly opposite points in the sky. That should be amazing.
