While there's no "Orbcomm" debris, the DPAF certainly qualifies as Taurus debris. Granted it was anticipated and part of the normal operating mode. But anything additional in orbit besides the operational satellites qualifies as debris. In a real sense the third stage of the Taurus (actually fourth stage if you count the Castor 120 but you know what I mean) also qualifies as debris. Certainly it - and its 30 "passengers" are a road hazard to other spacecraft.

The parameters are clearly that of an object in GTO. The only GTO object was the Ariane 3rd stage since this was a single satellite launch (e.g. no SPELDA). It seems strange that there should be two additional new objects so long after launch - possibly the first tracked objects from an 'event'?
