    Scott Tilly appears to have recovered IGS 7A (11075A / 37954):

    He sent me a circular orbit fit to his observations, which I have extended to include Kevin Fetter's observations:
    
    1 99105U          12197.24210438  .00000000  00000-0  00000-0 0    01

    The ground track repeats every 6 days (91:6).
    
    Kevin Fetter sent me additional observations of his UNID suspected of being 10062H / 37229. This is the complete set:

    Here are updated search elements for two different arguments of perigee:
    
    1 99201U          12197.14206254  .00000013  00000-0  50000-4 0    01
    2 99201  72.1100 257.9128 0130000 355.2371   4.7444 12.89540000    00
    
    1 99201U          12197.14193581  .00000013  00000-0  50000-4 0    09
    2 99201  72.1100 257.9061 0130000  92.2792 269.3162 12.89540000    07
    
    The first one fits best, but both yield similar predictions. Allow at least one minute prediction time error tonight.
