The final published elset for this decayer appears to be...

Prog M-39 Soyuz-U r                              146 x 141 km
1 25341U 98031B   98136.63033875  .20332878  12646-4  31391-3 0   153
2 25341  51.6181 206.0724 0003925  76.0794 284.0579 16.48308035   274

...which is 1.0 second early against the "9013" prediction I posted
earlier today. The previous elset showed it only 0.1 second early,
confirming that it was keeping quite close to the SatEvo evolution. My
conclusion is that decay occurred in darkness over the Indian Ocean as
it approached the northbound equator crossing at 18:02 UTC (May 16.75)
at 61 deg E longitude. Just a few minutes earlier it had passed within
about 300 km of the SE coast of South Africa, being SE of East London at
17:51 UTC, while it overflew Madagascar at 17:56. I wonder if anything
was seen.
