    Setup: Watec 902H2 video, 50mm F/1.8, NTP, Nexstar SLT mount
    IOD format: http://www.satobs.org/position/IODformat.html

    NOTES:
    ------
    
    (1) The plane of Kevin's 99210 unknown from July 4th was searched from
        21:20UT on the 18th to 01:30UT on the 19th. All elsets from my
        previous post (http://www.satobs.org/seesat/Jul-2013/0147.html)
        were targeted. At 23:44UT an object was seen perfectly on track
        and 2 seconds early with the 79174 elset. This is the search orbit
        that spanned 174 revolutions between Kevin's discovery
        observations and my recovery on July 16th. It is also the orbit
        that was the best fit to those observations!
    
        With these observations the orbit refines to:
    
    Unknown 130704
    1 99210U 13685A   13185.10295924  .00000000  00000-0  90535-3 0    02
    2 99210  63.3059 230.3059 0405425 116.5146 293.5592 13.57850474    04
    
        The object should also have been visible at 21:54UT but was not
        seen. Reexamination of my searches on July 6th and the second
        orbit on July 16th also did not show the object. Chances are it is
        variable in brightness.

       Cees
