Millions of people will have their eyes on the sky Monday as a total solar eclipse takes place.
In the Tri-Valley, residents will witness a partial solar eclipse as the moon will obscure approximately 75% of the sun at the maximum eclipse point, according to NASA.
The eclipse will start at 9:01 a.m., with the maximum eclipse anticipated at 10:16 a.m. It will be over by 11:38 a.m.
Everyone in North America plus parts of South America, Africa and Europe will see at least a partial solar eclipse, while those in portions of 14 states including Oregon, Montana and Georgia will be able to see the moon completely block the sun.
Eclipse viewers should not look directly at the sun without appropriate eye protection. Serious eye injury can occur without special eclipse glasses or other viewing methods like a sun funnel, NASA officials say.
The Pleasanton Library, located at 400 Old Bernal Ave., will be giving out 100 pairs of eclipse glasses on a first-come, first-served basis as part of a free viewing event from 8:30 to 11:30 a.m. Monday. Light refreshments will be served, and there will be a livestream of the total eclipse with commentary from NASA officials.
