Yes - it has decayed. The negative ndot2 term (-0.00003965) in the final elset meant that it was missed in my initial check for recent decayers. In fact, I think that possibly a more realistic elset for that rev is: Integral Proton deb E 184 x 125 km 1 27544U 02048E 02305.29200827 1.14146380 82062+1 13589-2 0 90114 2 27544 51.5339 32.2768 0045784 153.8022 206.4301 16.44315884 1772 ...with decay beyond the perigee on that orbit, possibly at ~07:46 UTC (on November 1) southbound near 6.3 deg S, 60.2 deg E. It is interesting that there was a pass across Europe shortly before this, from Paris at 07:27 to Athens at 07:32.
