red hot atomic fireballs

and a couple of weeks ago we had a rainstorm in which the wind gusted to perhaps 50-60 mph. we lost power for hours, and a pole out on the road was down. but during the storm, i saw a blue fire on that pole (which is a quarter mile away). i went outside and saw the damnedest thing. the blue fire out there flaired, and then a second later a fireball flew across our field. it started, i believe, at the top of a metal pole that marks our property line: a white ball trailing red sparks, and not near any power line at all. then the fire flaired again up on the road and the same thing happened. i would not have believed it if i hadn't seen it. anybody got some kind of explanation?
