OK - consensus is thunder then. Just trying to inject a little excitement into our day heh ! Yes, I'm aware of what thunder and lightning are, thanks
My immediate thought was of course thunder, but I guess I've never seen (or rather heard) one single, enormous crack of thunder with not a cloud in the sky and the sun so bright. I wasn't suggesting it wasn't possible, but that it was a little strange.
I still haven't heard anything since. Either way it was pretty cool so I'm not too fussed.
I have come to this thread two days late. In case you haven't seen it, it may be worth mentioning that I wrote about a similar event last week. Except for the folderol about ancient gods, what I wrote was factual, not exaggerated. bullworth says, 'it was pretty cool.' I go further. I think it was a truly extraordinary moment.
