    Notes:
    -------
    (1) #99999 has been earlier reported as #91034,#91035 and #99999.
    
    Many thanks to Ted Molczan,Mike McCants and Scott Campbell for fitting
    orbits to the observations which show this is a satellite in a 64 degree
    orbit with eccentricity around 0.7 and doing about 2.005 revs/day. I
    still have visibility for a few more days before loosing it to daylight.
    Maximum brightness about mag +5.
    
    (2) #91036 is a possible new unknown observed whilst waiting for another
    satellite- I do not find a match in my elements database. Appeared steady
    at about magnitude +6 during the few seconds observed.
    
    (3) Tomorrow I will report the other known 17 satellites observed on the
    21st July. The satellites are:
    
    USA 179 CnR, USA 32, Lacrosse 4,#90016,#90038,#90037,DMSP #23533 (95015A),
    Milstar 3 CnR,Noss 2-3 triplet, DMSP #09415 (76091A),DMSP #07816 (75043A),
    Noss 3-2 r,Lacrosse 2, USA 144 and Geosat FO #25157.
    
    
    Cheers
