13003 - SCI: GSAcq (1,3,1) failed to RGA hold due to SRLEX on FGS-1@250/1650z

19123-3 - Update OBAD Window size @250/1732z

19125-0 - Update OBAD Window size@259/2127z

2265-2 - Gyro 4 Motor Current Limit Change@250/2052z

FGS GSAcq		8		7
FGS REAcq		7		7
OBAD with Maneuver	8		6

Gyro 4 motor current flagged OOL high at 250/15:22:21.  

It has been verified that HST has been recovered to the science timeline with the successful 
completion of the guide star acquisition scheduled at 19:25.
