I have updated my Decay Watch page (URL below) with updated predictions
for #21867 = JERS 1 and the additional decayer #25155 = Inmarsat 3-F5
Spelda.
The JERS 1 entry reads:
_____________________________________________________________________
Object: #21867 = 92- 7 A = JERS 1

Note: There was some speculation that this decayer might have been
responsible for the re-entry seen over Texas and Oklahoma. In fact,
it is still due to decay on the 3rd, though the expected time has
continued to shift earlier. There is still an uncertainty of several
hours though my current estimate is for decay to occur northbound
over the USA on a track from western Florida at 06:44 UTC to Chicago
at 06:46 on the orbit given by the final SatEvo-predicted elset
above.
