China and the Western United States will be able to get a look at the annular eclipse, the first of its kind since 1994. The annular eclipse happens when the moon lines up between Earth and the Sun to create what looks like a ring of fire.

Not everyone's going to get the chance to watch it but you can catch it online. National Geographic says that the eclipse will only last for over four minutes.

The annular eclipse starts in China and then crosses the Pacific Ocean and will start to hit America in the late West Coast afternoon. National Geographic says:
The eclipse makes landfall again in North America in the late afternoon of May 20, starting at the California-Oregon border at 6:26 p.m. PT (9:26pm ET).

The annular eclipse then crosses southern Nevada, southern Utah, the Grand Canyon in northern Arizona, the lower-left corner of Colorado, and most of New Mexico before ending in the area of Lubbock, Texas, around sunset at 8:36 p.m. CT (9:36 ET).
You can watch the annular eclipse at the SLOOH Space Camera, which will stream telescopes along the annular path in Japan, California, Arizona and New Mexico starting at 5:30PM ET. And since its online you don't have to worry about damaging your eyes. But if you do plan to watch it in person, then be careful and remember to wear protective eye gear.
