The COS FUV Special Recovery activities (proposal 12810 visits 24 - 25) successfully completed 
today without incident.  The FUV was ramped to -5198V for segment A (172 counts) and -5151V (169 
count) for B.  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 (172/169).  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 26 and 27. Visits 26 and 27 
are scheduled for Tuesday June 12 (DOY 164).  The COS event flag 3 was cleared @163/15:40 via OR
