The nominal orbit given above has 2008 TC3 coming to within one earth
radius around Oct. 7.1. The absolute magnitude indicates that the
object will not survive passage through the atmosphere.
Steve Chesley (JPL) reports that atmospheric entry will occur on 2008
Oct 07 0246 UTC over northern Sudan.

Hi Christian, (And Rob Matson, who noticed the same problem) I got nailed by the use of the 'astronomical' convention, wherein S=0. Thanks for the catch....

Well, no, an entry angle of 18 degrees is way more than "grazing". An entry like the one over the Tetons in the U.S. had an entry angle that was mainly a...
