October 1997============================================================================== 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. DAY PLAN: Science Operations. COMMENTS: ============================================================================== DATE: 02-October-1997 DOY: 275 OPERATIONS ENGINEER(S): C. Haskell / R. Yurow SCIENTIST: D. Zarro CDS INSTRUMENT: A parity error was detected in the secondary (science) processor memory space. The seconary processor was rebooted at 19:16 UT. CDS GROUND SYSTEM: Nominal. DAY PLAN: Science Operations. COMMENTS: ============================================================================== DATE: 03-October-1997 DOY: 276 OPERATIONS ENGINEER(S): C. Haskell / R. Yurow SCIENTIST: D. Zarro CDS INSTRUMENT: Watchdog error occurred at 13:19 UT. LOBT sent at 14:19, and science resumed at 16:15 UT. CDS GROUND SYSTEM: Nominal. DAY PLAN: Science Operations. COMMENTS: ============================================================================== DATE: 04-October-1997 DOY: 277 OPERATIONS ENGINEER(S): A. Hammond/E. Donaldson SCIENTIST: B. Bromage CDS INSTRUMENT: Watchdog error occurred at 12:26 UT. LOBT sent at 13:21, and science resumed at 15:13 UT. An ASCVERR error occurred at 16:33 UT. This error is currently under investigation. CDS GROUND SYSTEM: Nominal. DAY PLAN: Science Operations. COMMENTS: ============================================================================== DATE: 05-October-1997 DOY: 278 OPERATIONS ENGINEER(S): A. Hammond/E. Donaldson SCIENTIST: B. Bromage CDS INSTRUMENT: Nominal. CDS GROUND SYSTEM: Nominal. DAY PLAN: Science Operations. COMMENTS: ============================================================================== DATE: 06-October-1997 DOY: 279 OPERATIONS ENGINEER(S): C. Haskell / R. Yurow SCIENTIST: B. Bromage CDS INSTRUMENT: Nominal. CDS GROUND SYSTEM: Nominal. DAY PLAN: Science Operations. COMMENTS: ============================================================================== DATE: 07-October-1997 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. DAY PLAN: Science Operations. COMMENTS: ============================================================================== 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. DAY PLAN: Science Operations. COMMENTS: ============================================================================== DATE: 09-October-1997 DOY: 282 OPERATIONS ENGINEER(S): C. Haskell / R. Yurow 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. DAY PLAN: Lube Study, VDS Memory Dump, Science Operations. COMMENTS: ============================================================================== DATE: 11-October-1997 DOY: 284 OPERATIONS ENGINEER(S): E. Donaldson/A. Hammond SCIENTIST: E. Alam CDS INSTRUMENT: Primary SEU detected at 80073bf7, which is an unused area, so a reboot is not necessary. CDS GROUND SYSTEM: switched archive to /cdsd3 DAY PLAN: Science Operations.
