[/QUOTE] As John said, it shouldn't really change in appearance over the next three weeks until Impact Day, and as to what happens then is still anyone's guess - it could brighten dramatically or show minimal change.[/QUOTE]
It might get spectacular if the impact projectile ruptures an unknown/unseen reservoir of highly compressed gas's that propels 9P spinning into a different orbit - and it becomes a 20klm diameter SUNGRAZER!!
I have seen some very amazing long duration pointer meteors that i like to imagine/pretend are my personal own supernovas
