The latest elset for the Centaur is:

Intelsat 705 Centaur r                           617 x 119 km
1 23529U 95013B   99036.90702257  .35660113 -84867-5  99969-3 0   583

This is only 12 seconds late against the prediction I posted here
yesterday. My new prediction is for decay at February 6.59 (14:04 UTC
+-3h). This is near 20 deg S, 143 deg E (Queensland, Australia) on the
approach towards a northbound equator crossing at 14:16 UTC near 174 deg
W.
