Astronomy News is a phone-in newsline of recent astronomy news, 
operated by Sky and Telescope magazine.  When I called a couple
of weeks ago they were citing a 1 in 10,000 chance of a collision,
given the current predictions of the comet's orbit.  I think they
were crediting Brian Marsden with this information (sorry if wrong
credit).  For anyone interested, the number is 617-497-4168, and 
the information is updated each Friday.

Also, someone was wondering whether the collision is before or
after perihelion.  On this newsline I believe I saw an earlier
posting indicating a July perihelion date, and an August 14
possible collision date.
