Partial Eclipse of Harvest Supermoon Can Be Seen Tonight: What to Expect

Canadians across the country will have a chance to see a partial eclipse of the harvest supermoon on Sept. 17.
“An imperfect alignment of Sun, Earth and Moon results in the Moon passing through only part of Earth’s umbra,” NASA said on its website. “The shadow grows and then recedes without ever entirely covering the Moon.”
The partial eclipse will begin around 8:41 p.m. ET on Sept. 17 but will still be difficult to see. Around 10:13 p.m. the top edge of the moon will start to enter the full shadow with the eclipse peaking around 10:44 p.m. At this time, the top eight percent of the moon will be in “full shadow,” NASA said.
The moon will exit the full shadow around 11:16 p.m. and the partial shadow on Sept. 18 at 12:47 a.m.
Tonight’s supermoon is the second of four consecutive supermoons this year. Another supermoon is expected in October, which will be the closest the moon will get to Earth. The final supermoon will be in November.
