CDS GROUND SYSTEM: Nominal. DAY PLAN: Science Operations. COMMENTS: ============================================================================== DATE: 02-August-1997 DOY: 214 OPERATIONS ENGINEER(S): R. Yurow SCIENTIST: T. Kucera 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. CDS GROUND SYSTEM: Nominal. DAY PLAN: Science Operations. COMMENTS: ============================================================================== DATE: 04-August-1997 DOY: 216 OPERATIONS ENGINEER(S): C. Haskell / R. Yurow SCIENTIST: T. Kucera CDS INSTRUMENT: Nominal. CDS GROUND SYSTEM: Nominal. DAY PLAN: Science Operations. COMMENTS: ============================================================================== DATE: 05-August-1997 DOY: 217 OPERATIONS ENGINEER(S): C. Haskell / R. Yurow SCIENTIST: T. Kucera CDS INSTRUMENT: 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. CDS GROUND SYSTEM: Nominal. DAY PLAN: Science Operations. COMMENTS: ============================================================================== DATE: 06-August-1997 DOY: 218 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. CDS GROUND SYSTEM: Nominal. DAY PLAN: Science Operations.

COMMENTS: ============================================================================== DATE: 18-August-1997 DOY: 230 OPERATIONS ENGINEER(S): C. Haskell / R. Yurow SCIENTIST: D. Zarro CDS INSTRUMENT: Nominal. CDS GROUND SYSTEM: Began implementation of a program divide QKL files into components which contain a contigous set of packets. Contigous QKL files will be written to /cdsr2. Original QKL files will be written to /cdsr1 by the ECS. DAY PLAN: Science Operations. COMMENTS: ============================================================================== DATE: 19-August-1997 DOY: 231 OPERATIONS ENGINEER(S): C. Haskell / R. Yurow SCIENTIST: D. Zarro CDS INSTRUMENT: A WATCHDOG error occured at 03:39 UT. The recovery procedure was completed at 06:24 UT and the science plan was restarted at 06:50 UT. The GIS software patch required reloading during the recovery. CDS is nominal after the recovery. CDS GROUND SYSTEM: Nominal. DAY PLAN: Science Operations.

Thompson CDS INSTRUMENT: 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. CDS GROUND SYSTEM: Nominal. DAY PLAN: Science Operations.
