    I don't normally post "I saw Mir"-type messages, but I'll make an exception
    because it was my first sighting of ISS after the docking of Zvezda. I saw
    it this night (30 July 00) at 04:26 UTC. It emerged from the Earth's shadow
    in the west-southwest under a favorable phase angle. It reached very quickly
    an astounding brilliance. By comparison with Jupiter (visible elsewhere in
    the sky), I estimate the maximum brightness at -2 mag. After having culminated
    at about 85 degres elevation, it descended in the eastern sky, losing several
    magnitudes. By coincidence, it passed exactly across the stars alpha Per and
    delta Per, providing a good opportunity to check the accuracy of my predictions.
