SIGNIFICANT EVENTS:
The COS FUV Special Recovery activities (proposal 12810, visits 12 - 13) successfully completed
today without incident. The FUV was ramped to the 1st HV plateau (-4916V/-4869V (154/151)) similar
to visit 6; however this time the QE grid was on, no elevated counts or HV current transients were
observed in the engineering telemetry during or after the ramp. The STScI and MOSES2 Engineering
Teams have examined the relevant telemetry and confirmed all voltages, currents and temperatures
were as expected. The voltage and current monitors matched the signatures seen in SMOV. The COS
Science Team at STScI has examined the science data and DCE memory dumps and everything is nominal.
No HV current transients or unexpected elevated count rates were observed in the DCE memory dumps.
The science data consisted of 2 sets of dark and wavecal exposures. The exposures were collected
immediately after ramping to HVNom (154/151) and an hour later at the same HV level. Comparisons
with SMOV data taken indicate comparable behavior when the aging of the detector and temporal
fluctuations are considered. The Engineering and Science Teams have given a "Go" to proceed with
visit 14 and 15. Visits 14 and 15 are scheduled for Friday June 1 (DOY 153). The COS event flag 3
was cleared @152/19:36 via OR 19251 -jb
