    Notes:
    ~~~~~~~
    
    (1) Objects 26905,26906 and 26907 observed in civil twilight- very few
        reference stars for positions, however should be okay.
    
    (2) Obj 26053 quite easy as it was tracked going out from about 12000
        kms out to 16000 kms.
    
    (3) Objects #20196 and #22739 going over at about same time as 96072A
        expected. Wasnt sure at the time what was what so measured all
        three satellites seen - the 3rd one was hopefully 96072A.
    
    (4) I will be tracking a few selected satellites tonight, one of which is
        96072A - still need to get a decent track on it after its recent
        orbit change. Ill be used the elements kindly generated by Pierre
        and Mike, in addition to mine (with clues from Bjorn). The spread
        between them is less than  a minute. I have a Cosmos rocket going
       over at the same time in the  field of view so will have to be careful
       which one I follow!
    
    (5) A few of the other satellites accidentally observed 8th December were
    
     #27433 02-024D 19h06m08s UT Feng Yun 1D Debri-mag+6.5 essentially steady
     #04367 70-025C 19h35m42s UT Nimbus 4 launch related-mag+7.5 steady
    
    Cheers
