    Matt, the Clarke orbit IS the geostationary orbit. Its a zero inclination
    circular orbit , period 1 sidereal day.
    
    Yes it is visible from your latitude. Its just on the horizon for those
    observers at 82 N or S. From an observers point of view the Clarke belt
    is one iof constant declination. At your latitude geosats are projected
    against the sky at declination about -6.5 degrees, while for me at 35S
    its declination +5.5degrees
    
    Since the flashing satellites we are particularly interested in  are
    out of control, they often have appreciable inclinations, which means
    the search region Ed cannon is referring to has a width of at least 20 degrees.
