Slow it down.
I’d like to kknow if it was “ground-to-cloud” lightning or “cloud-to-ground” lighning.
I, personally, am on the fence of whether it was lightning at all.
Technically, all the lightning we see is ground-to-cloud:
“A typical cloud-to-ground flash lowers a path of negative electricity (that we cannot see) towards the ground in a series of spurts. Objects on the ground generally have a positive charge. Since opposites attract, an upward streamer is sent out from the object about to be struck. When these two paths meet, a return stroke zips back up to the sky. It is the return stroke that produces the visible flash, but it all happens so fast - in about one-millionth of a second - so the human eye doesn’t see the actual formation of the stroke”
