    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....
