Summary
Spacecraft subsystems continue to operate nominally. The plans and
procedures for gyro calibrations are in place. The COS FUV high-voltage ramp-up and NUV
alignment activities continue according to plan. ACS first external observation (first light), a
SMOV cross-talk check, has occurred; analysis is ongoing. The WFC3 mechanism
checkouts and UVIS detector functional are proceeding per the plan; preliminary results are
all positive. The replan to resume the STIS NUV high-voltage ramp-up is in place for next
week.

• ACS proposals 11371 and 11510
• COS proposal 11469
• STIS proposal 11351
We now have 12 WFC3 associations errored in calibration
• from proposal 11419
• need a keyword rules change for these)
• 6 exposures for the same proposal with a missing bias
reference file.
o WFC3 team is looking into the problem
• We FTPed the files which have not been archived due to errors,
to the WFC3 team.
Mission schedule processing failed in the stisfringe process
• due to a failed database query on a temporary table that wasn't
found
• Under investigation
