Remarks I didn't get a good look at the object as I was looking at my cell phone screen at the time, but I clearly heard a boom (it was loud enough to scare my dog), then approximately a minute later I heard a second boom and then another minute or so later a third boom. Very distant booms but way more powerful sounding than guns, fireworks.
