Not sure if anyone is watching this comet but she is looking to be about 7 to 10 miles in diameter. She will pass us around oct 2011. There is a small chance of contact but not likely. A larger concern from what I have read is the tail. There is a cool web site that works out the scale of disaster based on some data inputs. You plug in the size,speed,distance and so on and it gives you the outfall likely to be seen, ( fire ball-air blast-rock fall). Calculated Results
