The calls began at about 10:45 a.m. Tuesday morning and came from across San Bernardino and Riverside counties, the Riverside Press-Enterprise reported Wednesday.

"We don't know a whole lot right now," said dispatch supervisor Tom Barnes of the San Bernardino County Fire Department. "We've taken quite a few calls. Everybody seems to be looking north to where they are."

Barnes said he has spoken with the state's Operation of Emergency Services, which is

investigating the sightings by residents from Temecula, Banning, Beaumont, Lake Arrowhead, Corona and desert communities.
