Flight Operations Summary

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


19035-0 - BQ9200 NSSC-1 Image Load Update@63/1745z


FGS GSAcq		7		7
FGS REAcq		8		8
OBAD with Maneuver	4		4

The March Anneal commanding for WFC3 in the 059 SMS has been completed nominally, including the 
updated stored commanding instructions to configure WFC3 Event Flags 4 and 5 in the NSSC-1 to 
manage ground limits for Anneal operations in the AO environment. Both flags were observed to set 
and subsequently clear as expected. Key transitions included: Op to PreHeat 062/00:59 Set WFC3 
Flags 4 & 5 ~062 00:59:20 PreHeat to CCDHeat 062/03:23 CCDHeat to PreHeat 062/16:09 PreHeat to Op 
062/20:55 Clear WFC3 Flags 4 & 5 ~ 062 22:19:56.   
The NSSC-1 image BQ9101 image was patched with BQ9200 image in HST486 RAM at 063/14:00:24. At 
063/14:21:22, HST486 RAM memory was dumped and verified by FSW.
