Most skywatchers will be unimpressed until things get really get interesting at 10:03 p.m. ET (02:03 UT), when Earth's total shadow, called the umbra, begins to take a bite out of the Moon.
The heart of the event, called totality, begins at 11:14 ET (03:14 UT) and ends at 12:07 a.m. ET Friday morning (04:07 UT).
The eclipse will be underway when the Moon rises in the Western United States. In Europe, the Moon will set while the eclipse is in progress.
