A strong solar storm could bring the Northern Lights to parts of Northern California on Friday night, but it could also disrupt power, TVs, and radios. The National Oceanic and Atmospheric Administration (NOAA) says the outbursts of plasma are capable of disrupting satellites in orbit and power grids on Earth. The agency issued a rare geometric storm watch — the first in nearly 20 years. The best chance for seeing the Northern Lights is between 1 a.m. and 4 a.m. Saturday. The images of the Northern Lights you usually see are from long-exposure cameras, so it won’t look exactly like that to the trained eye. If we see them on the northern horizon, it will look like a faint, green glow. They could be visible in parts of the Bay Area, and possibly as far south as Southern California. The best shot of seeing them will be in the Pacific Northwest.
