ACE Weekly Report:  11-15-00

All ACE spacecraft subsystems are performing nominally.  Attitude
maneuvers  were successfully executed on 11-09-00 and 11-15-00.  The
next attitude maneuver is scheduled
for 11-22-00.

During the 11-09-00 (DOY 314) support, the pressure in SEPICA's Fan
#3 fell ~18 torr. The Instrumenter was notified and is investigating.
No commands were sent to increase the 30kV power supply this week.
The Instrument team continues to analyze telemetry regarding the
recent SEPICA anomalies.

The ULEIS shutter was closed to the 6% position to avoid saturation
during the solar event on 11-09-00.  The shutter was returned to its
full position on 11-10-00.

Station 24 primary receiver failed on 11-10-00 causing a ~3 minute
telemetry outage.
All SSR data was recovered and no further problems were experienced
during the support [DR# G06497].

Memory checks of both SSRs were performed on 11-13-00 and 11-14-00.  No
additional SBEs were detected (SSR A was found to have 15 SBEs in
December 1999).
