Social media users reported seeing the blue flash of the meteor flying west around 8 p.m. Friday night, and sightings were reported throughout the Bay Area, from Santa Clara to Fairfield, and even in the Central Valley cities of Fresno and Stockton.

Jonathan Braidman, an astronomer with the Chabot Space and Science Center in Oakland, said that it appears that the three astronomical events seen Friday are unrelated. Friday's destructive meteor fall in Russia—reported to have injured 1,000 people, the asteroid flying closer to Earth than the orbit of the moon, and the meteor spotted in the Bay Area seem to be moving in different trajectories from the evidence he's seen, indicating they are from different points of origin, Braidman said.
