    There are lots of programs that can handle all the TLE in one file, or at
    least a substantial number!
    
    I didn't keep Ed's TLE, since 51 deg is difficult at my latitude, and ISS
    orbit "impossible" right now.
    Did he give predicted future elsets?
    
    Right now, last 5 elsets from OIG start:
    ISS (ZARYA)
    1 25544U 98067A   03161.19453943  .00016937  00000-0  21621-3 0  1015
    2 25544  51.6330  55.3767 0006612 234.8836 263.1097 15.59373879259913
    and:
    PROGRESS M1-10
    1 27823U 03025A   03161.21778569  .00071333  00000-0  26443-3 0   134
    2 27823  51.6332  55.5129 0006943 304.0056 206.3883 15.87406827   289
    So the perigee of ISS 385 km, and the apogee of Progress is 314 km,
    ie. not in transfer orbit yet, and distance is "meaningless" -
    becomes 0 in the horizontal direction Wednesday 09:13 UTC.
