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.)
