Hi Dirk:

Thanks for forwarding this post to us. When I see the CSS and Spacewatch
people, I will see if I can get an estimate for how much it would cost to
see everything down to 1 to 2 meters heading toward Earth (the detection
of the Sudan event was lucky and the person who discovered it did not even
know its importance when he went to bed that night).
