  The science plan was aborted at 20:01 UT in order to observe a C9 flare.
  At 20:07 UT the study MPIFLAR2 was started at the wrong location due to 
  errors calculating the pointing and using the wrong slit (6 instead of 1).
  GIS detectors 1, 3, 4 triped at 20:10 due to excessive count rates.  All 
  three detectors were reset by 20:12.  The MPIFLAR2 study was rerun at 
  20:14 with the correct slit, but still at the wrong location, at 20:12. 
  The normal science plan was resumed at 21:40 UT.

  A telemetry submode change from submode 5 (CDS medium rate) to submode 4

  A telemetry submode change from submode 4 (CDS low rate) to submode 5

  A telemetry submode change from submode 5 (CDS medium rate) to submode 4

  A mechanism lubrication study was completed at 22:29 UT.
  The NIS was reset at 22:49 UT clear the error status word.
  At 23:17 UT the CDHS crashed while uplinking the science plan for the 
  weekend.  The crash caused caused toggle bit errors on all subsequent 
  commands sent after the crash. CDS was reset at 00:24 UT DOY 303 and the
  LOBT was sent at 00:32 UT DOY 303.  During the reset, CDS came up on
  processor 1 resulting in a loss of all of the patched program modules.
  CDS was therefore put in a safe state until recovery efforts could 
  continue on DOY 303.

  CDS was returned to SNOOZE mode at 16:27 UT in order to begin uploading
  the CDHS patches which had been lost during the recovery of the previous
  day.  All 4 patches were reloaded by 17:15 UT, however a subsequent memory
  showed the defered module also appearing in the extended module list.
  Given the difficulties with doing a memory dump in telemetry submode 4, it
  was decided to continue on with the recovery.  In addtion to reloading the
  CDHS patches, all 3 GIS were also reloaded in order to bring the GIS
  software up to version 2.6. Reboot procedures were completed at 19:41 UT 
  and the science plan was resumed 20:20 UT, albeit with the wrong GSET due
  to a bug in CPT.
  A parity error was detected in the primary processor memory space at
  23:22 UT.  Since the error was in a safe location, no reboot was necessary.

  GIS detector 1 tripped at 2:47 UT, probably due to doing off limb
  observations with the wrong GSET.  
  The FOT reported that CTM31 began flagging intermittently.  This was caused
  by an elavated spacecraft panel temperature (~22.0 C).
