    We don't know where to look for the second stage - it may have had an
    impulse of unknown magnitude
    so could be any of A to V -one might guess A as it would be the easy
    thing to track.
    B is probably CASSIOPE
    Perhaps ALL of C to V are second stage insulation debris, and  the other
    payloads - POPACS, DANDE, CUSAT - have not yet been cataloged at all, and will
    only be spotted once they are far enough separated from CASSIOPE to be
    distinguishable!
