The object, described as a bright blue-green streak of light, was seen around 8:30 p.m. across Southern California skies down to San Diego.
Dr. Ed Krupp, director at the Griffith Observatory, said meteors pass through the sky every night, but every once in a while they end up being brighter than usual.
He didn't think this one was from the Perseid shower, which peaks at Aug. 11-12 every year but typically would not be seen that early in the evening.
"My suspicion is that it was just a bright meteor," Krupp said.
"It's always a good thing when people get to wish upon a star," he added.
