'Space junk' causes streak of green light above Southern California

LOS ANGELES -- A streak of bright green light appeared above Southern California on Tuesday.

The Griffith Observatory said it was not uncommon for this to occur.

In December 2015, Russian space debris was spotted over Southern California and Nevada, taking social media by storm.

Officials with the U.S. Strategic Command later stated a Russian SL-4 rocket body had reentered the atmosphere.

In November 2015, a missile test flight from a submarine left hundreds of people from Southern California, Nevada and Arizona perplexed as it caused a bright light to streak across the sky.
