Those of you who live in the North America^* will be treated to a total lunar eclipse tomorrow night (Monday night/Tuesday morning)! The whole thing unfolds over about 3.5 hours, starting at 1:30 a.m. Eastern time.

[...] Sky and Telescope’s website has an excellent description of the timeline. The Earth’s dark shadow takes its first bite starting around 1:32 a.m. Eastern time (all times will be Eastern from here on out). Over the next 45 minutes or so, the Moon will plunge deeper into shadow, and the entire disk will be covered starting at 2:41 a.m. It’ll stay this way for over an hour, and then at 3:53 a.m. will begin to leave the shadow. An hour or so later, at 5:00 a.m., it’s all over, and the Moon will be restored to being full. Note that the farther west you are, the earlier this happens in the evening. For me, in Mountain time, it starts at the much more palatable 11:32 p.m. Monday night.

To someone viewing from the United States, you’ll see the eclipse start on the lower left part of the Moon. It really will look like a bite is taken out, and that dark bite will grow left to right. When the Moon begins to leave the shadow you’ll see the upper left part of the Moon becoming bright, with the illumination growing from left to right.
