Remarks
before I saw this fireball (call this number 2) there was a huge explosion overhead but I am not sure what its trajectory was. Then this came right after as described but was not nearly as bright. Time is approx. I know it was between 0100 and 0130 local time. Had radio on so couldn't hear.
