CDS INSTRUMENT: 
  A parity error (SEU) was detected in the primary processor memory space.
  Since the parity error is at a safe location, no reboot is necessary.

  CUVMCP went into HIGH ALARM for 4 formats (60 sec.)
  A WATCHDOG error occured at 19:28 UT.  The recovery procedure was completed
  at 21:07 UT and the science plan was restarted at 23:11 UT.  CDS is nominal
  after the recovery.  The GIS patch required reloading during the reboot.

OPERATIONS ENGINEER(S): C. Haskell / R. Yurow
SCIENTIST: T. Kucera
CDS INSTRUMENT: Watchdog at 03:40 UT.  Instrument was rebooted at 07:31 UT, 
  and science resumed at 09:00 UT. 
  CTM18 went into high warning today at a value of 36 degrees.
  It stayed there for approximately 30 minutes.  The reason was the study
  G_SPIC_4.  This study runs for 5 minutes and moves the slit mechanism 
  between slits 4 and 6 within those 5 minutes.  The study was altered in 
  order to compensate for the slit motor problem.

  CPT began reuseing CDHSID numbers for sequences due to the maximum number 
  of entries in the rseries_id database table.  The database table size was
  expanded to correct for the problem.

  A WATCHDOG error occured at 08:30 UT.  The recovery procedure was completed
  at 18:18 UT and the science plan was restarted at 19:00 UT.  During the
  recovery, the GIS instrument latched up and refused to accept commands.
  The GIS was reset by bringing CDS back down to STANDBY mode.
  Due to an operator error, the study counter was not set correctly
  during the reboot.  It was latter reset.
