Flight Operations Summary

Significant Spacecraft Anomalies: (The following are preliminary reports
of potential non-nominal performance that will be investigated.)

SIGNIFICANT EVENTS:
Flash Report: COS Status:  
COS event flag2 has been successfully cleared in preparation for NUV fold test, this is the last 
time flag 2 will need to be cleared for this proposal .  
  
Flash Report: COS NUV Ready to Resume Science Operations The NUV MAMA Detector was shutdown as a 
result of the COS Suspend Event on April 30. The NUV Recovery from Anomalous Shutdown, started on 
DOY 128/15:10 UT, has been completed and the data analyzed. The engineering and science data 
(darks) obtained during the three-day Recovery Procedure indicate nominal performance of the MAMA 
detector and NUV channel electronics. A check of the PtNe lamp that was on at the time of the COS 
FUV over-light event has also indicated normal operation. The first science use of the NUV since 
the COS Suspend Event on April 30 is scheduled for the week of May 14. The preparations needed to 
initiate the FUV recovery, including proposal review and processing, VSTIF testing and scheduling 
will take place over the next two weeks.
