    subject: Results observations Cosmos 2421 satellite (2010/04/05)
    Hereby my presentation of observing results of a favorable pass of
    the suspected disintegrated Cosmos 2421 sat, orbiting at an altitude
    comparable with the ISS and subject of an important ISS-avoidance
    maneuver in 2008. 
    As I reported earlier, when inspecting the first frames of the session,
    the captured object gave an impression to be pretty big, too large to
    be just a small piece of a fully fragmented satellite. 
    Interesting as well, is that Russian Space Officials have repeatedly
    denied that this satellite exploded at all. 
    I would keep the question open, but at least my own impression is
    that the satellite shows in the recent images too much size and shape
    to be fragmented, especially if you can make out clearly its solar panels:
    Best regards,
    Ralf Vandebergh
