A total eclipse of the moon tonight is expected to delight skywatchers across the United States and much of the world. It will be the last total lunar eclipse until 2010.
The easy-to-watch event will play out in several stages as Earth’s shadow blocks sunlight from shining on the moon. Weather permitting, the eclipse will be visible from all locations in the United States, according to NASA. Along the Oregon and northern California coasts, the moon will rise during the early stages of the eclipse, however.
Here’s how it will go down:
The moon will enter Earth’s umbral shadow (the full shadow) at 8:43 p.m. ET on Wednesday, Feb. 20. It will appear as though an ever-larger bite is being taken out of the moon.
Some 78 minutes later, the moon will slip into full eclipse. About 51 minutes later, a bright scallop will appear as the moon starts emerging. It will be completely out of the umbral shadow at 9:09 p.m. Pacific time, which is 12:09 a.m. ET on Thursday morning.
