Alberto, you observed 09061B / 36089, not 96072A / 24680. The latter made a small manoeuvre on Mar 11, which lowered its orbit. Those of us who updated the orbit interpreted this as a large increase in drag, which did not fully reflect the magnitude of the change of orbit. As a result, on your second pass last night, it was about 21 s early. You had no way to know this, so you could easily have missed it. Here are approximate elements, based on Russell Eberst's observations of Mar 11 UTC and Derek Breit's first observation of Mar 13 UTC: 1 24680U 96072A 10073.14255387 .00014645 00000-0 22019-3 0 00 2 24680 97.7843 126.4863 0452489 273.7090 81.2510 14.86444060 04 Derek obtained video on his second pass, which should yield additional points. I will update the elements ASAP after he posts those observations.
