I was just driving at night here on the East Coast and saw a giant flaming ball streaking across the sky. It was moving relatively fast but much slower than a shooting star or meteor I’ve seen in the past. I had time to watch it move parallel across the horizon and even film it/take photos. After about a minute it just suddenly disappeared into nothing midway through the sky. It was not a rocket as there aren’t any launches/returns scheduled tonight. I can not overstate how large it was - it was not a plane or anything similar. Super awesome to witness but would love some insight into what I actually just saw! I’ve heard rumors of a comet being visible for the last week or so but was told by others this is not what they saw?
