    The NOSS satellites must be geometrically/structurally interesting with some
    sort of large reflecting surfaces.  In the SeeSat archives there are at
    least two records of very bright passes.  One was from an observer along the
    western US coast (I think California) and another was observed by a group of
    local amateur astronomers here at home (Winnipeg, Canada).  The local pass
    here I did not see, but I know those who saw it quite well.  They were taken
    back by a group of 3 satellites "as bright as Jupiter" that climbed in
    azimuth in the western evening sky.  Fading away as they climbed high.  When
    I did a sat search for a possible hit, the NOSS trio was bang on.
    
    I myself remember seeing one pass where overhead they were possibly naked
    eye, for sure an easy binocular object.  But as they lowered in the eastern
    sky toward the horizon they became naked-eye at around 20 degrees azimuth.
    For a line of sight at 20 degrees azimuth they must have been very far away,
    yet they were easily around 3 to 4th mag.
    
    Interesting.
    
    Does anyone know what these birds might look like?
