"Mysterious Green Fireball Spotted Across Southwestern Skies"
Residents across Southern California, Nevada, and Arizona witnessed a green fireball in the sky, initially sparking speculation about a decommissioned SpaceX satellite or the Geminid meteor shower. NASA clarified that the phenomenon was caused by debris from the 3200 Phaethon asteroid, with peak activity expected in mid-December. Witnesses described the object as a large, bright, comet-like presence with a long green tail, and some managed to capture the event on camera. The Geminid meteor shower is an ongoing celestial event that can be observed throughout much of December.
