Orbit Number -- 98218
Pass Highlights: Station DSS-66 AOS 1155 LOS 1530
Pass Summary: Recorder dump. Performed a successful attitude
maneuver. The S3DPU had a processor reset during the night which triggered
a current spike on SEPICA. SEPICA was turned off by an autonomy bin, and
SWICS and SWIMS went into Standby mode.
FOT executed OCR to place SWICS and SWIMS instruments in a safe
mode. SEPICA power on is being coordinated with the SEPICA instrument team
for execution later in the week.
Anomalies: 1. Autonomy bin 30 fired during the night at 0741Z.
this bin turned off SEPICA. Also, SWIMS and SWICS were observed to be in
Standby mode at AOS.
SWIMS, SWICS, and SEPICA instrumenters began analysis, and OCR
SWX/SWM-008 (SWICS/SWIMS safing) was executed.
2. FOT was unable to command to C&DH B on initial acquisition due
to incorrect command mod index setting at DSS-66 (DR #L02383). This was
corrected by DSS66 personnel.

Pass Highlights: station: DSS-16 AOS=14:56:31 LOS=18:30:00
Pass Summary:
- During daily SSR playback started receiving VC2 frames at about
1 frame per/second instead of 10/1. Resolution to problem resulted in 1
hr 15 min of missing SSR data which will be recovered on Day 240.
- Extensive anomaly resolution indicated that a process on the
prime fanout box was corrupted that operators were unable to detect.
Prime fanout was switched to backup and problem was cleared.
- Solar Flare activity has decreased and SIS instrument tuned
detectors for non-flare operations.
