Anomalies:

DOY 175 (06/24/05) ACE Anomaly G05-0084  FORMATS Transmit Error
The FORMATS software is designed to retransmit ACE products if the FTP was
unsuccessful.   After the connection to NOAA was unsuccessful on
2005:175:16:27:35, FORMATS did a full transmission and tried to transmit
files that had already been sent and deleted.  The resulting error messages
were documented.
IMPACT:  None.  All files reached their destination.

DOY 178 (06/27/05) ACE Anomaly G05-0085  Video Monitor Failure
An HP A4331A Monitor failed (ac3ws1) and was repaired by Hardware
Maintenance.
IMPACT:  Minimal.  Video monitor was for String 3 (backup string)

DOY 179 (06/28/05) ACE Anomaly G05-0086  Erroneous Pass Change Message
The ROBOTT software checks the pass schedule for the current DOY and the
following DOY.  The information is retrieved from DSN's 7-day schedule and
view file.  When checking for DOY 180, ROBOTT incorrectly included view data
with an event description of "180 DEG AZIMUTH".  An erroneous Pass Change
notification was generated.
IMPACT:  Minimal.  The problem was with the pass-check program, not the
cron-generator program.

DOY 180 (06/29/05) ACE Anomaly G05-0087  TSTOL Syntax Error
A recently updated TSTOL procedure for SSR redumps produced a syntax error
when performing variable substitution.  Appropriate GOTO statements were
performed and the procedure was completed successfully.  The procedure has
been corrected.
IMPACT:  Minimal.  The procedure was manually executed at the time of the
error.

DOY 181 (06/30/05) ACE Anomaly G05-0088  GDS DSS-27  CMD System Problems
Problems with the Command Processor Assembly at the station was resolved
after 6 reboots.
IMPACT:  Activities delayed 68 minutes.  Data will be captured during next
support.
