At around 9:30pm PDT a loud boom was heard across an at least 5 mile radius in the 95033 zip code.
There were some local reports in a newsgroup of windows being rattled and houses being shaken.
Somebody also heard 2 pops like gunfire about 10 minutes before the loud boom.
Been trying to find media reports but so far nothing.
Considering there was the Lyrid meteor shower going on that night, I'd say probability of a fireball related sonic boom is high.
