Alberto Rango's and Mike Waterman's observations on consecutive passes revealed the object running significantly late and off-track; it had made another manoeuvre. In my analysis, I considered both an apogee-raising and a perigee-raising, and found that the latter produced somewhat better residuals. To produce the following elset, I propagated my pre-manoeuvre elset, and then corrected only the RAAN, mean anomaly and mean motion, while setting eccentricity to maintain the pre-manoeuvre perigee distance.
