Early risers can expect to see a spectacle in the sky on Wednesday. Just before sunrise, the moon will be fully eclipsed by the Earth’s shadow, and NASA expects the sight to be a very colorful one — even from the most light-polluted cities.
Viewers on the East Coast of North America should look the sky around 6:25 a.m. local time. On the West Coast, viewers will start to see the action around 3:25 a.m. local time.
The moon will turn a dim red due to the sunlight scattered through the Earth’s atmosphere, according to NASA.
Some will also be able to see a band of turquoise, likely just before and after the moon is fully eclipsed by the Earth’s shadow. This is due to the ozone layer, which absorbs red light as sunlight passes through the Earth’s atmosphere. The turquoise rim is best seen through binoculars or a small telescope.
