Tucson, Arizona - Something caused some shaking, rattling, and rolling over many parts of Tucson Wednesday night. It happened about 7:45 p.m.

Tucson News Now was inundated with calls from people asking what it was. We made calls to several law enforcement agencies and Davis-Monthan Air Force Base. D-M says it was not one of their aircraft that caused a sonic boom.

Capt. Adam Goldberg from Northwest Fire District says all the area fire departments received about 100 calls. The Tucson Fire Department says most of their calls came from the west side of Tucson.

Tom Peine with the Pima County Sheriff's Department tweeted, "We checked with variety of places to include mines, DMAFB, Pinal Army Nat. Guard, TIA, SW Gas, El Paso Gas, TEP/So far all negative."

Peine also tweeted, "calls reference "boom" seem to come from W of Campbell/from Pinal County line to northern Green Valley/still trying to determine source." Within 20 minutes on my Facebook page, I had more than 200 comments from people all over the Tucson valley saying they felt it and heard it, just as I did myself. I also had a lot of people tweeting about it too, saying it was felt from Oro Valley all the way to Rita Ranch on the southeast side.

Genna Short posted, "East central side. Mostly my windows rattled." Melba Alderete Munoz wrote, "Windows rattled, in the downtown area." Cindy Calderon Weltjen posted, "3-4 large booms that shook our house. Silverbell between Sunset/Ina. Our dogs didn't like it either!"

Summer Desrosiers Parker posted on the Tucson News Now Facebook page, "There was something in the sky after the bang. It looked like a lot of debris slow falling and shiny. I am on the Far East side (golf links and Harrison) and I was looking towards the base when I saw it."

We'll continue making calls. In the meantime, please go to my Facebook page to tell me what you felt and which part of town you're in.
