    Now I am a very happy camper
    
    Thanks to some help from the tech guy (Brian Edwards) of satellite tool kit 
    ( STK) , I can now find out where the iss will be seen going across the sun 
    and now moon.
    
    After a little trouble, I got the program to work.
    
    Using this orbital element for the iss
    
    ISS (ZARYA)
    1 25544U 98067A   02220.15028755  .00019974  00000-0  27256-3 0   243

    And using the sun, since rob's program, doesn't work with the moon.
    
    Here is the sample output of rob's program

    151696659.367453
    
    There results match, with just very slightly different answers. But that to 
    be expected, due to the ways the calculate and output the data.
    
    So now I will no longer need to bug rob, that should make rob very happy.  I 
    tested the results using project pluto's guide 8.0, so I know it works:)
    
    
    Thanks
    
    Kevin
