DATE:  01-October-1997
DOY: 274
OPERATIONS ENGINEER(S): C. Haskell / R. Yurow
SCIENTIST: D. Zarro
CDS INSTRUMENT: 
  A WATCHDOG error occurred at 17:27 UT.  The recovery procedure was completed
  at 18:09 UT and the science plan was restarted at 18:45 UT.  CDS is nominal
  after the recovery.
CDS GROUND SYSTEM: Nominal.

DOY: 280
OPERATIONS ENGINEER(S): C. Haskell / R. Yurow
SCIENTIST: B. Bromage
CDS INSTRUMENT:
  A WATCHDOG error occurred at 18:19 UT.  The rocovery was completed at 
  19:37 UT, and the science plan was resumed at 19:52 UT.  CDS is nominal 
  after the recovery.
  A parity error was detected in the secondary (science) processor memory
  space.  No action was taken due to a subsequent WATCHDOG error on 
  DOY 281
CDS GROUND SYSTEM: Nominal.

DATE:  08-October-1997
DOY: 281
OPERATIONS ENGINEER(S): C. Haskell / R. Yurow
SCIENTIST: B. Bromage
CDS INSTRUMENT:
  A WATCHDOG error occurred at 02:30 UT.  The rocovery was completed at 
  04:53 UT, and the science plan was resumed at 06:34 UT.  CDS is nominal 
  after the recovery.
  A swap of the primary/secondary processors was performed today.  There 
  were a number of problems with the ground stations which delayed the 
  completion.  Two new scripts were implemented to do the switch, 
  POWER_SEC_PROC1 and RESTART_SEC_PROC1.  Also, czcprpu2 was needed to 
  boot from processor #2.  All was nominal with the change.    
CDS GROUND SYSTEM: 
  Due to an error in the way CPT tries to generate commands to change the
  slit position when the option to "ALLOW ADJUSTMENT OF MIRROR AND SLIT 
  POSITIONS TO AVOID OPS MOVEMENT" was chosen, certain series tables could
  not be uploaded to CDS.  CPT was then rerun with this option disabled 
  and all the series tables uploaded correctly.

SCIENTIST: B. Bromage
CDS INSTRUMENT: 
  A Lubrication study was performed. 
  A test of the VDS memory dump was performed.  It appears to have been
  successful.  
CDS GROUND SYSTEM: 
  The following raster durations were updated:

	Raster		New Duration
	146/1		600
	38/28		4100
	38/27		2350
	11/43		2230
	147/1		2400
	10/48		2350
	10/44		14500
	145/1		1250
	145/2		1250
	10/49		14500

  The update of raster 10/44 to 14500 s may have been a mistake.
