"Pseudo-MPEC" for 9U01FF6

Created Sun Dec 1 17:37:04 2013 using Find_Orb

Peter Birtwhistle has suggested that this object may be the same as UDA34A3 = UW8551D. I think he's probably right. However, there are some lunar flybys between the arcs, and I haven't been able to link them yet... perhaps once we get more astrometry.
