"SIGNIFICANT EVENTS: Flash Report: SBC - preliminary results - The first SBC images (science and calibration) were acquired today (Day 051). All the telemetry indicates normal conditions. The first internal flats and dark frames are consistent with those pre-dating the ACS Side 2 failure. There may be a small degradation in sensitivity (on the order of 1% or less at the shortest wavelengths). More sensitivity data will be acquired in the coming week."
Flash Report: As of 047/16:22:43 ACS is configured to its Safe mode on Side 1, and the on-board SMAC20 has been updated to the new version M to support ACS Side 1 SBC-only operations. Flash Report: As of 048/00:28:33. ACS CS FSW 4.02A has been successfully loaded, validated, and activated in the transition to the Operate state.
