Hi all - 

Here's one for Paul's list:

I love the neologism: "Dark Comets". Its one whole word shorter than "dead 
comet fragments". Maybe that is all that was needed: a catchy name that sums up 
the problem.

I don't think that anyone has ever done visible wavelength to IR conversion 
studies on any carbonaceous chondrites - anyone know any different?

PS - Mike, the off-site back up slogan is "daily by the week, weekly by the 
month, monthly by the year". Parallel or mirrored drives work pretty well, and 
it is best to store sensitive information on a machine not connected to the net 
in any way.
