I couldn't find if this was an intra-cloud flash or if it was a sky-to-ground strike. Anybody know?

Space is 60 miles away, and this was over 500 miles. Maybe it hit the ground eventually, but the vast majority of the strike was definitely intra-cloud.

By the animation it appears to be cloud to cloud.

Edit: I saw the animation in a different article. I'll come back if I can find it.
