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.
