    Both Ed Cannon and Brad Young spotted this unknown again
    on Saturday evening after an interval of 3 days.
    
    My best guess is a mean motion of 2.33:
    
    Unk 070914    
    1 90077U 07757A   07266.04090415 0.00000800  00000-0  61820-3 0    04
    2 90077  28.1149 225.5919 7211623  30.9192 329.0806  2.33711000    04
    
    There is a small chance that the correct answer is mean motion 2.67:
    
    Unk 070914    
    1 90077U 07757A   07266.04422606 0.00000400  00000-0  16652-2 0    03
    2 90077  28.1613 226.9959 6875665  32.2890 327.7108  2.67092803    00
    
    A typical pass has looked like this forecast for tomorrow night:
    
    30.3  97.9  Bee Caves Rsrch Ctr

      Mag Hrs Min  Alt  Azi    Hgt  Range
      5.2   1  52   49  225    546    692
      4.7   1  53   67  180    643    692
      4.8   1  54   62  125    749    831
      5.3   1  55   51  106    863   1051
      5.8   1  56   43   98    984   1309
      6.3   1  57   37   94   1111   1582
      6.7   1  58   33   92   1244   1862
      7.0   1  59   29   90   1381   2144
    
    So it has been seen going quite fast near azimuth 180 and it
    goes into the Earth's shadow about 7 minutes later about 30 degrees
    up in the east.  It helped a lot to have a different perspective
    on the orbit from Tulsa.
