SIGNIFICANT EVENTS:
The FSW updates associated with COS SCR 343 were successfully patched (via SMS122) to Exec RAM at 
122/00:12.  This FSW change was to the patchable constants that defines the WCA to PSA/BOA offsets 
(pcta_CalTargetOffset). These constants are used during the FUV LTAPKXD phase of a disperse light 
target acquisition. The adjustment was 2 pixels in the positive cross dispersion direction. These 
updates were successfully used at 122/01:08 (Proposal 12276), the science data analysis is still 
pending.  The SPC instruction successfully patched Exec RAM, but the command to copy these values 
to EEPROM was missing. The instruction that was originally delivered had the correct commanding 
sequence, however when it was modified to set up memory monitors the EEPROM copy macro was dropped. 
My review of the PASS products fails to catch this omission. Operationally this has no impact on 
science, the new values defined in SCR 343 are being employed, however to make these changes 
permanent, they need to be copied to EEPROM. I will draft an OR in the morning to perform the 
necessary commanding as well as an EEPROM memory dump.  -jb   John J. Bacinski HST Payload Systems

Ops request 19096-0 was successfully executed at 122/20:55 today. The patchable constants loaded to 
Exec RAM last night via SMS were successfully copy to EEPROM in R/T. A EEPROM dump was also 
performed. The FSW team compared the DUMP to the GMI and found no difference. The COS in-flight 
Exec RAM and EEPROM memory now reflect the LV0045 FSW version.    Thanks to the FOT and SI FSW team 
for their excellent and efficient support.    -jb .  John J. Bacinski HST Payload Systems Engineer
