The first total solar eclipse across the United States in nearly 40 years will cast partial darkness over Southern California Monday in a rare celestial event. The moon will block the sun over a nearly two-hour span, yielding a total eclipse only on parts of the North American continent.
The best views will be in the Pacific Northwest, across a large swath of the nation's midsection and the southeastern United States. The sun's corona, normally seen only during a total eclipse, will be entirely hidden behind the moon beginning about 10 a.m. as viewed from the coast of Oregon. From there, totality will continue for the next 90 minutes, cutting across the nation's midsection.
Southern California will be in the penumbra, or partially shaded area, with roughly 60 percent of the sun in shade. Several locations in Southern California are offer opportunities for watching, and many will feature experts in all things sun and moon.
Top news of the day
As with most any spectacle of the sky, keep the forecast in mind. Southern California coastal residents may want to head inland to ensure a chance of seeing Monday's eclipse. NBC4 forecasters say a persistent marine layer will bring low clouds and fog from the night through morning along the coast and extending into some valleys.
