Social media exploded Monday night after a bright green flash crossed the sky over at around 9 p.m.
Eastlake resident Faye Heddings caught it camera and posted the video on Twitter.

The bright light was seen across Southern California and as far east as Arizona, according to KABC-TV in Los Angeles.
Several people in San Diego County, from Escondido to Chula Vista, described what they saw on Facebook.
It remains unclear if the flash was a meteor or something else entirely.
