Hmmm, the epoch is Feb 13, two days after Classification of Geosynchronous Objects 13 (COGO) was released, which identified ISON's UI.094 as PAS 6. That object was first reported in COGO 8. Here are the reported elements in TLE form: PAS 6 1 24891U 97040A 11001.00000000 .00000000 00000-0 00000-0 0 00 2 24891 13.5885 4.0938 0693850 117.4835 296.7720 0.93694643 07 The same report also identified a couple of Proton-M fourth stages (Briz-M). One is ISON's UI.153, which first appeared in COGO 11: Thor 5 r 1 96153U 08006C 11001.00000000 .00000000 00000-0 00000-0 0 04 2 96153 3.6328 45.6259 0260112 191.0820 170.1067 0.95115847 04 USSTRATCOM has yet to catalogue this object, so I used our number. The other Proton rocket body appeared for the first time. I believe that USSTRATCOM has set aside 36398 for that object: Intelsat 16 r 1 36398U 10006B 11001.00000000 .00000000 00000-0 00000-0 0 02 2 36398 0.6267 81.0395 0441702 308.5765 123.4267 0.86944835 02 I imagine that USSTRATCOM eventually will report TLEs of those objects. The SBSS (Space Based Space Surveillance) satellites can be expected to improve the reliability of USSTRATCOM's high altitude catalogue and TLEs.
