The Yavapai County Sheriff's Office says they have received multiple calls of a loud boom in the Prescott area Tuesday night.
This comes after reports of a loud boom Sunday morning in Yavapai County. Experts say a meteor may have caused it.
Meteor expert Robert Ward lives in the Prescott area and heard the boom on Sunday.
"I jumped up out of bed. Grabbed my phone. Ran out on the balcony and it was boom, boom, boom, boom, boom, boom, boom and the house was shaking so I got my camera and the persistent train is right there in the sky so we started videotaping," said Ward.
Ward says the meteor may have been the size of a microwave or refrigerator before breaking up in our atmosphere which is why it made such a loud sound for most in Yavapai County to hear.
He says he's unable to confirm if the latest boom was a meteor or not. "I'm scratching my head too--this is quite baffling."
Ward said he was outside when the boom supposedly happened, but did not hear anything.
YCSO says they are monitoring the situation.
