Anomalies:

DOY 03032 (02/01/2003) - ACE Anomaly Report #S03-0004  Mnemonic TANK_A2_T 
Yellow Low Limit Violation
At 15:20:02, the mnemonic TANK_A2_T violated the yellow low limit of 10, 
with a value of 9.6472.
At 15:20:10, the mnemonic TANK_A2_T returned to within limits.  This has 
happened before.  Reference AR S02-0024.  The FOT is still investigating 
this.  It does not look like a temperature fluctuation, but more like 
something with the temperature sensor.  IMPACT: None at this time.

DOY 03037 (02/06/2003) - ACE Anomaly Report #G03-0005  GDS(DSS-27) DSN - 
TGC Reboot / Late AOS
At 14:48:00, DSS-27 informed the FOT that telemetry would be late (expected 
AOS 14:50:00).  DSS-27 reported they loss interface to TGC-5.  At 14:54:37, 
telemetry was put online. IMPACT: None.  All telemetry was recovered.
