    While Spacetrack has label the newly launched Cryosat 2 (2010-013A) correctly 
    the objects 2010-013B (marked as SL-24 R/B) and and 2010-013C (marked as 
    SL-24 Deb) seemed to be named wrongly. Object B has a lower perigee (685 km) 
    than Cryosat while object C has a higher apogee (1120 km). At spacecraft 
    separation the protective shroud was let go slightly before Cryosat and 
    should have a lower perigee while the actual booster kept on firing after 
    releasing the payload and should have a higher apogee. So object C is the 
    booster while object B is the shroud (or debris).
    
    Meanwhile our old friend Dana who spends his fifth winter at the South Pole 
    managed to take a picture of Cryosat itself (with resulting frostbites on his 
    fingers as the temperature was -73 deg C!).
