Starting at 9:36 p.m. EST Jan. 20, skywatchers will notice a “little notch is taken out of the moon,” according to Brian Murphy, director of Indiana’s Holcomb Observatory & Planetarium and Butler University professor.
“The moon starts to enter into the earth’s shadow in a portion called the umbra when the sun is totally blocked out,” he said. “Earth is moving from right to left through the shadow.”
At 10:34 p.m., it moves into a partial eclipse, and starting at 11:41 p.m., the full eclipse begins; a maximum eclipse occurs at 12:12 a.m. Jan. 21. The total eclipse ends at 12:44 a.m.
