CDS GROUND SYSTEM: 
  While uploading the weekend plan, NRT was disabled due to station problems. 
  CDS commanding was disabled.  EOF software was reset and CDS was unable to 
  get the Plan uploaded in time.  XCPT was run again, removing FFCAL/v1 and 
TRIM22N/v29 (studies that had already past).

CDS INSTRUMENT: 
  The science plan was reloaded (15:33 UT) and resumed at 16:00 UT.
  At ~19:00 UT it was noticed that CDS had executed the first study in the
  plan that was loaded at 15:33 UT.  It then halted without moving on to the
  next study.  Reasons for this anomally are undetermined at this time.
  At 20:41 UT the science was manually resumed.

  Two parity errors was detected in the secondary (science) processor memory
  space.  The secondary processor was rebooted at 18:24 UT to clear the 
  parity errors that had accumulated in its memory space.  In addition, the
  NIS was reset at the same time in order to clear the error status flags.
  A lubrication study was completed at 18:00 UT.
