Flash Reports: COS Status:  
At ~128/12:32 COS was successfully recovered to CS operate.   
NUV Status:  
The NUV anomalous recovery Part 1 (LV enabled and count rate check) successfully completed at 
128:15:27.  STScI Engineering  and the  SISEs have reviewed the data and have found that all 
voltages, currents, and temperatures are within expected values. When the threshold voltage was 
reduced to 0.28V, the number of ORCounts received (~41,000 counts/second) was within the expected 
value for a charge amplifier temperature  of ~3 dgC . These values are consistent to those obtained 
during SMOV4. The signal processing electronics appears to be alive and functioning properly.  I 
have conferred with Tom Wheeler and he recommends clearing event flag 2 and allowing the SPC to 
proceed with visit 2 of the recovery tomorrow morning (129/15:04 - 15:59).  
Line Lamp1 Status:  
The Line lamp1 test has completed.  During the period the lamp was on all the currents, voltages 
and temperatures were nominal. The lamp test was suppose to power on the lamp at medium current for 
10 mins, however a TERMEXP was issued at the end of a FGS guiding period pulling down the TDF.  
Since the COS TDF response was enable, the Protect Detector task was called which turned off the 
lamp. The lamp was planned to be powered from 128 15:35:00 to 128 15:45:02 however the TERMEXP and 
subsequent Protect Detector task call shut it off at 128 15:38:04. This is not a problem and 
sufficient telemetry was collected to show the lamp was functioning as expected.
