Final elset (6 sec late against yesterday's final prediction):
Irid 14A CSL02r 9.6 3.4 0.0 4.5 d 20 147 x 118 km
1 25779U 99032C 99194.01593597 .30668510 -13536-5 20543-3 0 1064

Note: This kept quite close to the decay schedule I predicted
yesterday. I put decay on a northbound track to the N of China. It
is possible that it survived to cross southbound over E Canada
and the NE USA (02:23 UTC) en route to the Caribbean and Venezuela
(02:31), but probably not much further.
