Significant Spacecraft Anomalies: (The following are preliminary reports
of potential non-nominal performance that will be investigated.)

Flash Report - Successful Gyro 6 Power On As part of the gyro reconfiguration effort, Gyro 6 was 
successfully powered on at 2011/075/19:21:31. Heater operation was verified to be on the primary 
controller. Subsequent gyro operation was nominal and the subsequent vehicle slew at 19:28 and GS 
acquisition at 19:43 were successful. A bias update occurred at 20:44 with values of [-1.3, 16.0 
18.6] arcsec/hr, so the thermal environment change in RSU 3 (gyros 5 & 6) did not significantly 
perturb the gyro 5 bias.
