I have had nearly the same experience twice, 3 to 4 days apart. The first time, I saw a bright white light in the sky exactly opposite the moon hovering in one spot. About an hour later, I noticed the light was gone. I laid down for the night and heard a distant explosion. The cows (I live right in the middle of a pasture) let out one loud bellowing "moo" all in unison, then nothing else happened. 3 to 4 days later (tonight) I saw a bright flash across my living room and heard another very loud explosion and it was much closer this time. Close enough to rattle the windows of my house. The cows did not make any sounds this time.
