It seems to have been at around the same time and area. That's the first time I've seen anything like that. It was unexpected and pretty impressive. I must have just thought it was stationary, because it freaked me out a little bit, I thought I might have been witness to some huge cosmic event!
Thanks for clearing up the confusion.
