It now appears that the elset for 00078.377, the latest one at the
time of my previous prediction, is a rogue that had skewed the
prediction. A new analysis including the four further elsets (over 13
hours) published in the past four hours suggests that the elset had the
object some three seconds too late at the equator crossing, probably
because it had a bad eccentricity. Excluding the elset gives an earlier
decay; indeed, the later elsets are all within two seconds of the
prediction I had posted yesterday.
I now put the decay on a SE pass over S China. Earlier in the
orbit it crosses Europe from S Portugal at 21:59 UTC, to Madrid, Spain
(22:00), Lyon, France (22:02), Munich, Germany, at 22:03 and Krakow,
Poland, at 22:05.
My new prediction for the final revs:
