DOY: 279
OPERATIONS ENGINEER(S): C. Haskell / R. Yurow
SCIENTIST:  
CDS INSTRUMENT: 
  CDS Temperatures have stabilized to:
  	QTCI1A = 26.01 C
  	QTCI1B = 26.38 C 
  	QTCR1 = 24.90 C
  	QTCR2 = 15.71 C
  	QTCR3 = 18.59 C
 The duty cycle remains at 90% for both substitution heaters.
CDS GROUND SYSTEM: Nominal.
DAY PLAN: Thermal Monitoring.

OPERATIONS ENGINEER(S): C. Haskell / J. Payne
SCIENTIST: 
CDS INSTRUMENT: 
 CDS was switched on at 19:55 UT.  The CDHS and EPS were nominal.  The MCU
 was also switched on and the  heaters were turned on.  They were nominal.
 The mirror and slit mechanisms were checked out and were nominal.
CDS GROUND SYSTEM: Nominal.
DAY PLAN: CDS Turn on.

OPERATIONS ENGINEER(S): C. Haskell / j. Payne
SCIENTIST: 
CDS INSTRUMENT:
  CDS remained ON overnight.  The commissioning of the OPS was completed 
  succesfully. The Mirror and Slit mechanisms were also exercised.  The 
  patching of the CDHS was completed without problems as were the table 
  loads and dumps. CDS was placed into STANDBY Mode and the secondary 
  processor was powerd on. 
  The s/c heater duty cycle was lowered from 90% to 70% for both heaters.    
CDS GROUND SYSTEM: Nominal.
DAY PLAN: Commissioning Activities.

DOY: 292
OPERATIONS ENGINEER(S): C. Haskell / J. Payne 
SCIENTIST: 
CDS INSTRUMENT: 
  The NIS and GIS electrical systems were succesfully commissioned. 
  The GIS HV's were ramped to 3.9KV and showed dark counts on all four 
  detectors.
  The s/c heater duty cycle was lowered from 70% to 60% for both heaters.
CDS GROUND SYSTEM: Nominal.
DAY PLAN: Commissioning Activities.

DATE:  20-Oct-1998
DOY: 293
OPERATIONS ENGINEER(S): C. Haskell / J. Payne
SCIENTIST: W. Thompson
CDS INSTRUMENT: 
  CDS was transitioned to READY_BOTH (science mode), and the S/C substitution
  heaters turned off. 
  Initial NIS science studies (FULLCCD) were performed with the MCP turned
  off and turned on.  Detector fuctionality appeared to be nominal
CDS GROUND SYSTEM: Nominal.
DAY PLAN: Commissioning Activities.

DOY: 294
OPERATIONS ENGINEER(S): C. Haskell / J. Payne
SCIENTIST: W. Thompson 
CDS INSTRUMENT:  
  A NIS Memory dump was performed.
  The GIS ran a short science study with the doors closed and succesfully 
  sent back stim data. Both the GIS and NIS doors  were opened and the 
  first science test studies run.  A GIS spectra was also taken on the
  quite sun at sun centre. All appears nomormal.    
CDS GROUND SYSTEM: Nominal.
DAY PLAN: Commissioning Activities.

DOY: 295
OPERATIONS ENGINEER(S): C. Haskell / J. Payne
SCIENTIST: W. Thompson
CDS INSTRUMENT:
  Nominal.  Began the recalibration of the NIS.
  A parity error was detected in the secondary (science) processor memory
  space.  
CDS GROUND SYSTEM: Nominal.
DAY PLAN: Commissioning Activities.

OPERATIONS ENGINEER(S): R. Yurow / J. Payne 
SCIENTIST: W. Thompson
CDS INSTRUMENT: 
  A lubrication study was completed at 20:30 UT.
  The secondary (science) processor was rebooted at 21:02 UT.  
CDS GROUND SYSTEM: Nominal.
DAY PLAN: Lubrication Study, Commissioning Activities.

  Nominal.  Science Operations using the DCS were resumed during NRT only.
CDS GROUND SYSTEM: 
  Fixed emon_logs cron job.  Installed plot_qcm.  Updated emon and qcm logs.

OPERATIONS ENGINEER(S): R. Yurow / J. Payne 
SCIENTIST: W. Thompson
CDS INSTRUMENT:  
  A parity error was detected in the primary processor memory space.  As the
  parity error is in a safe location, no reboot is necessary.
