Anomalies:

DOY 128 (05/08/05) ACE Anomaly S05-0015  SWICS Yellow Limit Violations
SWICS had 6 brief (<36 seconds) yellow low limit violations (SSCGR20V < 17V
and SSCPAP5V < 4.25V) during the increased solar activity on DOY 128 between
15:20:16 and 18:45:01.  All violations were within 0.1Volts of the currently
defined limit.  Jim Raines notified.
IMPACT:  Awaiting instructions from Jim Raines if necessary.

DOY 131 (05/11/05) ACE Anomaly G05-0074  26m GDS DSS-16 CMD Mod Index
CMDs were not being received by the spacecraft.  FOT notified station.
Station re-entered CMD Mod Index and CMDs were accepted by the spacecraft.
DSN has opened a work order for SBE1 not maintaining the MOD level.
DR#G105638
IMPACT:  Activities delayed 6 minutes.

DOY 131 (05/11/05) ACE Anomaly G05-0075  Network data loss
From 14:18z to End-Of-Track (17:20z), network drops resulted in ~1% data
loss.  JPL Comm was unable to determine the cause.  All data was available
on CDR.  DR#N102846
IMPACT:  Minimal.  CDR file was ingested for TAPS.
