My own current predictions:
# Designation Name Predicted decay (UTC)
25579 98- 74 C Iridium 11A CZ-2C r January 20.9 +-0.7d
25065 97- 74 C ETS-7 H2 r January 28 +-3d
The Iridium 11A Long March rocket, #25579, enters eclipse while
northbound near 26 deg S latitude at ~04:00 local time and leaves
eclipse while southbound over the arctic near 80 deg N at ~15.00 local
time. It reaches its low perigee while northbound in the N hemisphere so
there is a good chance of re-entry over that hemisphere.
