    Several sources identify 2012-017A/38248 as the payload and 
    2012-017B/38249 as the launcher. They are incorrect. SpaceTrack has them 
    reversed from normal convention. The reason for the error is probably 
    the slightly higher, elliptical, orbit of the PSLV upper stage. It is 
    due to a collision avoidance manoeuvre (check back to RISat 2 in 2009 - 
    it did the same).
    Identification of 2012-017B/38249 as the payloadwas confirmed shortly 
    after launch through radio tracking from Sweden by Sven Grahn. His 
    observations today show that 2012-017B/38249 has raised its orbit.
    Expect SpaceTrack to swap the two objects around once it realises.
