I've seen ball lightning too, a very long time ago, when I was a mid teen living in Australia. It was probably around 10 - 11 p.m. in summer time as it was dark, I'd gotten into bed and the lights were all out, when I became aware it was becoming light outside my window. Curious as to what it was, I got up and peered out. I saw a pale pink, brightly glowing ball of light which was appeared to be floating downwards and diagonally from my viewpoint. It was in my neighbour's paddock (we lived rurally). It really lit up the area, and then it vanished or disappeared behind something, perhaps, as there was a fence and stables. I hadn't heard of ball lightning back then so had no idea what the strange light was! It's only years later that I believe it was ball lightning. Where I lived (outside Melbourne) we often had severe storms in summer time, but there was no thunder and lightning at the time (however as it was dark, could have been a storm brewing in the vicinity). I expect I recorded it in my diary at the time, I still have them up in our loft, I should search for it!
