    Just checked first frames of the session, and shape is very well recognized.
    Size of the remnant must be considerable
    I wonder that this satellite actually fragmented in so many pieces as
    reported.
    Results later....

    April 5, 19:51 UTC, imaged great 81°pass of Cosmos 2421 sat. It was at an
    obvious
    mag 1.6, guess this must be the largest piece of the sat. Apparant speed was
    comparable
    with ISS, as it orbits at 350-360 km. In 2008, there was an ISS avoidance
    manoeuvre for
    one of the pieces of this sat: http://tinyurl.com/6jz2p8
    
    Anyone an idea of dimensions of this biggest piece? Images not processed
    yet,
    results later....
    
    regards,
    Ralf Vandebergh
