Lopezian photographer Geroge Willis took these photos of the annular eclipse in Zion National Park, Utah on Sunday.

An annular eclipse occurs when the moon’s orbit is at its furthest point from the Earth and closer to the much larger sun, which allows the moon to block more than 90 percent of the sun’s powerful rays when the two orbs slide into alignment.

The eclipse was first visible over southern Asia and then moved across the Pacific, and later crossed parts of Oregon, Nevada, Utah, Arizona and New Mexico before disappearing in Texas with the sunset.
