The eclipse will begin at 5:24 p.m., Sunday, with the moon fully covering the sun at 6:38 p.m. The moon will clear the sun's path at 7:42 p.m.
Griffith Observatory in Los Angeles will have extra telescopes available so people can see the eclipse for free.
"They'll be seeing something that is really unusual -- a big bite coming out of the sun," said Observatory director Ed Krupp. "And that's the real charm of this event."
The Los Angeles Times reports the best views will be near Eureka, Redding, Sacramento and Lake Tahoe.
NASA has also set up an interactive Google map, which will show when the eclipse will begin and end anywhere in the world.
