Yurow SCIENTIST: D. Zarro CDS INSTRUMENT: Nominal CDS GROUND SYSTEM: CPT crashed again, and the emergency study commands in place for Saturday morning were not removed by CPT. They were removed manually. DAY PLAN: Science Operations.

COMMENTS: ============================================================================== DATE: 24-June-1998 DOY: 175 OPERATIONS ENGINEER(S): R. Yurow SCIENTIST: W. Thompson CDS INSTRUMENT: Doors closed for thruster firing at 13:02 UT. Submode switch from 6 to 5 at 12:26 UT went smoothly. An ESR occurred at 23:08 UT. CDS was placed into Emergency_Standby mode and then properly booted into Standby mode. CDS GROUND SYSTEM: Nominal DAY PLAN: Science Operations. COMMENTS: ============================================================================== DATE: 25-June-1998 DOY: 176 OPERATIONS ENGINEER(S): R. Yurow SCIENTIST: W. Thompson CDS INSTRUMENT: At 02:35 UT, a second ESR occurs. Due to concerns that CDS could trigger a Thermal Re-Configuration if QTCR2 and 3 continue to drop, CDS sends the 'cb5rboth' command to put the processors into READY_BOTH mode. Temperatures stabilized after the command was sent. At 04:43 UT, FOT lost contact with SOHO. Status reports will cease until contact is resumed.
