There is going to be a total lunar eclipse tonight. The main event begins at 9:01 p.m. ET, when the moon is completely covered by the darkest part of Earth’s shadow. That translates to 8:01 p.m. CT, 7:01 p.m. MT and 6:01 p.m. PT. The total phase of the eclipse lasts 51 minutes, and the moon starts coming out of the darkest shadow, or umbra, at 9:52 p.m. ET.
