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

13261 - SCI: TDF Dropped Before End of Exposure@060/0417z

13263 - SCI: REAcq (1,3,1) failed to RGA Hold due to Scan Step Limit Exceeded on FGS-3@085/1209z


2307-0 - SCI: Update SOI after COS and STIS FSW install (LV48, OV10)@86/1326z

FGS GSAcq		7		7
FGS REAcq		8		8
OBAD with Maneuver	6		6

At ~ 086/00:40 COS and STIS successfully transition back-up to CS operate, thus activating FSW LV48 
and O10 respectively. No errors were observed. By 01:12 COS NUV and FUV detectors had successfully 
transitioned to HVSAA and HVLow respectively.  STIS/CCD cool down/stabilization is proceeding 
nominally and is scheduled to complete around 03:39. STIS and COS 1st exposure are scheduled for 
05:04 and 17:22 respectively.  A follow-up flash will only be issued if anomalous behavior is 
observed.  -jb  John J. Bacinski HST Payload Systems Engineer
