SIGNIFICANT EVENTS:
The COS FUV HV and OSM G130M (SCR 339 and 342) FSW patches has been confirmed via a COS EEPROM 
memory dump. The SI FSW team has analyzed the dump and confirmed no differences when compared to 
the LV0044 ground reference image.   
  
FLASH COS FUV HV FSW patches successful At ~ 066/00:15 the COS FUV segment B nominal operating HV 
preset was successfully updated in Executive RAM and copied to EEPROM. Additionally the maximum FUV 
HV FSW limits which were already in Exec RAM were copied to EEPROM. Segment B nominal operating 
voltage was increased from 167 to 175 counts (delta ~125.6 volts). These changes were monitored via 
COS memory monitors. These updates are documented in COS SCR 339. The updated segment B nominal 
operating voltage preset will not be used by the FUV until it is loaded to the DCE via the LDCECONF 
macro which occurs 11.067 19:31:06.000. The new G130M central wavelength positions were also 
updated in Exec RAM and copied to EEPROM.
