FGS ACQ STATUS:
SCHEDULED SUCCESSFUL
FGS GSAcq 9 9
FGS REAcq 7 7
OBAD with Maneuver 6 6

SIGNIFICANT EVENTS:
At 355/05:10 the COS FUV nominal operating HV absolute values have been successfully increased.

At 355/11:20 the COS FUV nominal operating HVs were restored to their default settings. The
exposures executed at the increased voltages have been successful collected and dumped to the SSR.
