Significant Spacecraft Anomalies: (The following are preliminary reports of potential non-nominal performance that will be investigated.) HSTARs: none COMPLETED OPS REQUEST: 19267-0 - Clear COS Event Flag 3 for prop 12810 visits 22-23@159/1727z COMPLETED OPS NOTES: none FGS ACQ STATUS: SCHEDULED SUCCESSFUL FGS GSAcq 6 6 FGS REAcq 10 10 OBAD with Maneuver 6 6 SIGNIFICANT EVENTS: The COS FUV Special Recovery activities (proposal 12810 visits 20 - 21) successfully completed today without incident. The FUV was ramped to the 3rd HV plateau (-5105V/-5057V (166/163)) with the QE grid 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 (166/163) and an hour later at the same HV level. Comparisons with SMOV data taken indicates 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 22 and 23. Visits 22 and 23 are scheduled for Friday June 8th (DOY 160). The COS event flag 3 was cleared @159/17:26 via OR 19267 -jb
