1992-047H (#22067) Proton AUX MOT (Name given by SPACECOM) Decay (as SPACECOM reported): 19 December, 09:06 UTC +/- 02 hours Björn Gimle remarked: "Was this really a rocket (admittedly a small final stage)? Whith this drag magnitude (and Bstar = 0.11, about one thousend times as high as a normal satellite/rocket) it seems more like a sheet of metal debris, or an empty discarded tank ?" Right! My approach for a decay prediction with MPM + REENTRY based on the normal input parameters for an Auxiliary Motor showed an unrealistic result (a more then 2 days later decay). With the last five ELSETs I calculated the ballistic coefficient of #22067. The result: About only 1 kg / m² drag area. A typical value for debris. Also the RCS (0.2834 m²) looked like debris. The "normal" RCS values for the Auxiliary Motors are in the range of 0.8 - 1.2 m². I believe SPACECOM had misidentified #22067. The real AUX MOT is 1992-047K (#24938) with a RCS of 0.8119 m² and a very similiar behaviour in orbit over the years like his "twin" 1992-042G (#22066) the other AUX MOT - both with MMs around 4.2.
