Off-topic I guess, but I still want to tell ; P
I once saw a "permanent" arcing between clouds.
I was out in a rowing boat on a lake in the mountains. Evening time, quite a
few clouds, but also clear sky in between. Between two adjacent clouds there
was a "permanent" arc going on. Permanent in the sense that it was going on
for the time the gap wasn't occluded by some other clouds, so it was something
like 30 seconds. No sound eminating from the arc, that I could discern.
Weird and nice at the same time :)
