A single low boom, but it was very delayed by at least 1 minute, so hard to say if it was a coincidence.

Remarks
There were several pieces. I didn't see the initial flash directly but saw it indirectly by the flash on the ground that would be similar to lightning since it flickered quickly. But there were no clouds in the sky. Then I looked up and for maybe a second saw multiple pieces. Then it went dark.
