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

The bright light was seen across Southern California and as far east as Arizona, according to 10News' ABC affiliate in Los Angeles.
Several 10News viewers 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.
