    Jonathan McDowell has some of the Mir TLEs during this period:
    
    http://www.planet4589.org/space/elements/16600/S16609
    
    Fortunately, my paper archive of the full catalogue TLEs (issued three times weekly by NASA/GSFC/OIG) includes the entire period of
    interest. I pulled the file to be certain, and it appears to be complete. Here is a sample, from July 15:
    
    1 16609U 86 17  A 86196.86025805  .00007127  00000-0  49539-4 0  2262
    2 16609  51.6187  87.6508 0026418 339.3182  20.6846 15.74259450 23043
    
    1 16643U 86 22  A 86196.98701252  .00113251  00000-0  74829-3 0  1192
    2 16643  51.6218  87.0013 0024771 339.9076  18.9640 15.74299139 19640
    
    The above appears to be the last Soyuz T-15 elset issued.
    
    I will transcribe all of the missing elsets that I find, and put them on satobs.org.
