The first reports came from Riverside County around 7 p.m. Wednesday. Within a half hour of the first reports, several Orange County residents also reported seeing the lights. After about an hour, reports were coming from all over the West.
Most say the lights are “blue and green.” A few described the lights as yellow or orange.
UPDATE: (8:30 p.m.): Some residents of Arizona have reported seeing the lights as well.
UPDATE: (8:52 p.m.): Residents of Nevada, many in Las Vegas, are also reporting the green-blue lights in the sky.
UFO’s? Several days ago, NASA announced a dead satellite would fall to Earth by “September’s end” but so far, no official confirmation if the lights and satellite are linked.
"We can't say 100 percent,"said Don Yeomans, manager of NASA's Near-Earth Object Program, "but it's almost certain that the object was a fireball" or very bright meteor, "the size of a basketball or baseball that likely disintegrated before it hit the ground."
The bluish-green color suggests the object had some magnesium or nickel in it, Yeomans said. Orange is usually an indication it's entering earth's atmosphere at several miles per second, a moderate rate of speed.
