[meteorite-list] 2004 MN4 updated odds

[Matson, Robert]

Hi Stan and List,

Latest updated odds of impact for the 4/13/2029 encounter are
about 1 in 37 at JPL's site.  (Odds haven't been updated at
NEODyS yet -- still 1 in 45 there).  Mind you, these aren't
the true odds of impact, but rather a measure of our current
uncertainty in the orbit.  With each passing day, the orbital
arc is extended by about 1/2 of one percent, so the cloud of
possible solutions 24.3 years from now is slowly shrinking.
