    Notes:
    -------
    
    (1) Terrible viewing conditions - thick cirrus.Eventually forced me
        to stop.
    
    (2) #91090 on limit of system - had to do many more integrations than
        usual to show the satellite. NSS 7 by comparison was a lot easier.
    
    (3) Dont know when next Ill be observing - I seem to be living under
        perpetual cirrus at the moment.
    
    Cheers
    Greg
