    Notes:
    ======
    
    (1) Despite an intensive search in which I varied the drag term of #90045
        I did not see it. If it was there I would have seen it.
    
    (2) #90027 NOT seen so it has probably moved.
    
    (3) #90020 did short duration bright flashes the entire pass - wonder if
        its tumbling or what. Has not changed orbit for the past six months
        so is it still operational?
    
    (4) #90041 visibility seems over for me as it has drifted from low in
        the west to now being low in the east over the past few months.
    
    (5) Many thanks to all who replied to my query re accuracy of different
        prediction programs - it really helped me. I actually located a
        small error in my prediction program - unfortunately not affecting
        #90027 but giving incorrect answers when the B* drag term was
        negative.
    
    Cheers
    Greg
