Thanks for all the (unfortunately negative) reports. This one kept going and going... (but I think it is down now) The final elsets from OIG were: Iridm 69 CZ r 10.0 3.0 0.0 4.5 d 174 x 127 km 1 25321U 98026C 98158.32757099 .16197737 -96548-6 20721-3 0 1336 2 25321 86.3224 275.6778 0036363 22.8842 337.4378 16.45843550 5673 Iridm 69 CZ r 10.0 3.0 0.0 4.5 d 163 x 124 km 1 25321U 98026C 98158.38833279 .14674012 -12136-5 15131-3 0 1341 2 25321 86.3249 275.6465 0029808 42.3417 318.3720 16.48326710 5681 Iridm 69 CZ r 10.0 3.0 0.0 4.5 d 128 x 117 km 1 25321U 98026C 98158.50957176 -.48118245 -14423-5 -22672-3 0 1369 2 25321 86.3218 275.5713 0008200 33.8551 327.0040 16.56420592 5706 Iridm 69 CZ r 10.0 3.0 0.0 4.5 d 127 x 110 km 1 25321U 98026C 98158.56997804 .24558294 -16985-5 94005-4 0 1377 2 25321 86.3198 275.5366 0012854 5.5493 355.1966 16.57905241 5718 The last two are certainly inconsistent - one has a strongly negative drag (a bit unlikely), they have too-similar mean motions and the drag on the final one is probably too low. Unless the final elset is a prediction, the rocket was still in orbit at the northbound equator crossing at 13:40 UTC. My best guess is that decay was on the latter orbit, possibly near the southbound equator crossing at 14:24 UTC near 16 deg W longitude. At least this has given me some useful data to improve SatEvo. My hunch is that, not for the first time, the lifetime was extended at the death by the rocket experiencing a changed atmospheric flow regime near perigee; a shift from so-called free-molecule flow to "slip" flow. For something as long as a Long March rocket, the effect would be to approximately halve that drag coefficient (and double its remaining lifetime) as its perigee fell below ~130 km - just about what was observed.
