Anomalies:

DOY 194  07/13/2007  S-ACE-0209  G07-0065  DSS-54 Late Acquisition
The ground station had problems with the Receiver & Ranging Processor (RRP)
at Beginning Of Track.  DR M104332
IMPACT:  Activities delayed 15 minutes.

DOY 199  07/18/2007  S-ACE-0210  G07-0066  DSS-27 Network Problems
Intermittent dropouts from 1614z to 1634z resulted in 14 minutes of data
loss.  The problem was initially attributed to the Reliable Network Server
(RNS) at the ground station.  DR pending.
IMPACT:  Minimal.  Data is available on CDR.

DOY 199  07/18/2007  S-ACE-0211  G07-0067  Duplicate Clock Reports Sent
When operations transitioned back to String 1, the clock calibration reports
that had been generated during testing were not deleted.  Duplicate reports
for DOY 191 through 199 were sent to ASC and NOAA.
IMPACT:  Minimal.  The duplicate reports contained the same data and had no
impact on ASC and NOAA.
