The recent SpaceCom notices are:

               -------------------------------

The final published elset for Sputnik 41 is:

Sputnik 41       0.2  0.0  0.0  9.5 v            138 x 137 km
1 25533U 98062C   99011.27784502  .36532436  12708-4  37292-3 0  1316
2 25533  51.6341  60.1503 0001083  50.3915 309.7247 16.50803227  9678

This has it 13 seconds early with respect to yesterday's final SatEvo
prediction. I put decay at January 11.32 (07:45 +-1h), only a little 
earlier than do Harro Zimmer or SpaceCom.
