People in several counties in our viewing area wondering "what was that sound?"

Dozens of you have let us know about a "loud boom" or explosion between 6:30 and 8:30 Saturday night.

KSPR has received reports about it from Mount Vernon, Nixa, Ozark, Aurora, and Reeds Spring but so far authorities say they've been unable to determine the source of the blast.

We can rule out an earthquake, the last one recorded anywhere near the Ozarks was more than 12 hours ago near Oklahoma City.
