For at least the next week, this object (using the orbital data above) 
is making good, near-perigee passes over the southern USA.  I think that 
reasonable estimated intrinsic magnitudes for a Centaur are Quicksat +2.0, 
Molczan +3.5.  It's likely to be tumbling.  I was going to look for it 
this morning but our morning low clouds prevented it, in spite of seeing 
a monster HST pass about 25 minutes earlier.  (Given the mostly cloudy 
conditions, this had to have been one of the brightest HST passes that 
I've ever seen.)
