398 11/12/06 345 234 Routine mission operations
399 12/12/06 346 235 Routine Mission operations run on VEMCB
400 13/12/06 347 236 Routine mission operations run on VEMCB
401 14/12/06 348 237 Routine mission operations run on VEMCB
402 15/12/06 349 238 Routine mission operations.  Shortened pass due to monthly maintenance at CEB.

Operations swapped to VEMCA configured as prime.
403 16/12/06 350 239 Routine mission operations
404 17/12/06 351 240 Routine mission operations
405 18/12/06 352 241 Routine mission operations

Spacecraft Status

On 5 and 6 December flight dynamics reported noisy Doppler data - which is likely caused by a solar flare.

Mission Planning

Short Term Planning
POR pre check was performed for STP034, STP035, STP 036 and STP037.

Medium Term Planning
The planning for MTP012 has been completed successfully, the activities have been approved.

Long Term Planning
Finally a decision has been taken to request DSN support for the "movie"observation.  This will be confirmed in a later report.

Future Milestones

The second Earth occultation season has started with additional Radio Science operations with the ESA New Norcia station.

Planning of the entire Christmas period will be completed this week (STPs 34 through 37, plus MTPs 11 and 12).
