    Early this year, I began work on producing TLEs of the rocket from observations
    published by The Smithsonian Astrophysical Observatory, made by Moonwatch and
    professional observers. Below are the first rough results, which I consider to
    be experimental:
    
    1 70000U          57285.20764492  .00415570  00000-0  82093-3 0    05
    2 70000  65.1000 318.3919 0522423  48.4377 316.0327 15.02609988    00
    
    1 70000U          57287.40213265  .00544215  00000-0  10083-2 0    04
    2 70000  65.1000 311.5463 0514752  47.4932 316.8494 15.05077108    00
    
    1 70000U          57288.53122459  .00561247  00000-0  96940-3 0    04
    2 70000  65.0851 308.0946 0512550  44.1260 319.9580 15.06368045    06
    
    1 70000U          57292.50918986  .00530031  00000-0  92279-3 0    02
    2 70000  65.0156 295.5226 0493792  42.1953 321.6087 15.10512095    01
    
    Check sums likely are incorrect, due to my having edited the ID using a text
    editor.
    
    These should be accurate to within a minute or two in time, and perhaps several
    tenths of a degree in track, for predictions within a few days of epoch.
