DATE: 01-Nov-1999
DOY: 305
OPERATIONS ENGINEER(S):  R. Yurow
SCIENTIST: J. Brosius
CDS INSTRUMENT: 
  CTM31 continued to flag YELLOW high intermittently.
  GIS detector 1 was reenabled at 16:06 UT
  A telemetry submode transition from submode 4 (CDS low rate) to submode 5
  (CDS medium rate) occurred at 20:12 UT.
  CDS was brought down to SNOOZE mode at 21:12 in order to reload all 
  CDHS patches (it was decided that this necessary due to possible
  complications from the recovery on DOY 303).  The CDHS memory was then
  cleared and all CDHS patches were reloaded from the ground.  The CDS
  recovery was completed at 00:17 UT DOY 305 and science plan resumed at
  02:00 UT DOY 305.
CDS GROUND SYSTEM: Nominal.

DOY: 306
OPERATIONS ENGINEER(S):  R. Yurow
SCIENTIST: J. Brosius
CDS INSTRUMENT: 
  GIS detector 3 tripped at 2:01 UT.  Apparent cause of the trip was high
  curent as the MCP voltage was switched from 1.0 KV to 2.0 KV.  Detector 3
  was reset at 17:40 UT.  The detector was disabled at 23:14 UT pending 
  further investigation.
  A parity error in the primary processor memory space was detected.  Since
  the parity error is in a safe location, no reboot is necessary.
CDS GROUND SYSTEM: Nominal.

DOY: 307
OPERATIONS ENGINEER(S):  R. Yurow
SCIENTIST: J. Brosius
CDS INSTRUMENT: 
  A parity error occurred in the primary processor memory space.  Since the 
  parity error is in an unused location, no reboot is necessary.
  The GIS was reset at 00:00 UT DOY 308 and all three patches were reloaded 
  the bring the software up to version 2.6.  Following the reset, GIS 
  detector 3 high voltage tests were conducted.  
CDS GROUND SYSTEM: 
  The following studies were imported to the EOF:
	ffcal_3_1.def	ID 223 / Var 1
