DMSP-16 observation

I caught DMSP-16 (the newly-launched USAF weather satellite) this
evening (7:52 PM, MDT; from northern Utah).  It was about sixth 
magnitude in binoculars, and accompanied by a second object; this 
object was of similar magnitude and did not vary in brightness.  
When I spotted the second object it was about two degrees west of
DMSP-16, and trailing it by about one degree.  As I watched the 
second object drifted to the east, appearing to cross DMSP-16's orbit.
This took about a minute (sorry I'm not more exact, but I was
too surprised for that).

Heavens-above hasn't yet listed any predictions for any other objects
launched with this satellite, so I have no idea what I saw--debris?
a classified subsatellite?  It didn't seem bright enough to have
been the Titan 2 upper stage.  Whatever it was, it was an interesting 
experience to watch them cross orbits.
