Its probably a different variant of the Centaur Ron, ( Titan IVb/Centaur
rather than Atlas 2AS),
but 96 72B had a molczan standard mag about 4.0  when first seen.
Ted later changed this to 4.8 . I mention this because orbit plane
similar geometry, although this orbit is circular while of course
96 72B's wasnt ( 180by 1000Km to start with).
