SIGNIFICANT EVENTS:
Flash Report: FSW 3.6A RAM Installation  
  
FSW 3.6 Release A was successfully installed into HST486 RAM.  The RAM loads and patch operation to 
activate FSW 3.6A were completed at 102/12:49:44, which initialized FSW 3.6A in VSS operations.  
The M1G pointer patch to the Kalman Filter Controller constants was completed at 102/12:51:53.  The 
safemode support loads for RGRW were completed at 102/13:21:49.  The post-installation RAM dump was 
completed at 102/14:38:29 and verified by FSW. The FSW 3.6A EEPROM installation will be performed 
tomorrow, 103/14:06:42 – 15:39:15.
