1:02 AM: We heard it too; have since received a phone call and various messages. Police are checking it out, and the scanner indicates 911 has received more than a few calls, too. We’ll update here if we hear anything definitive is found.
1:16 AM: Just to note – about 15 minutes have gone by, and there’s no report of smoke, fire, injury, anywhere, so far. Police are still checking out some of the various reports called in to 911.
2:11 AM: Nothing reported found, that we’ve heard. A WSB’er who lives on the northwest edge of The Junction reported a flash from outside concurrent with the boom, though.
