were reported.

)

       The WF/PC-2 was used to make observations of the low mass binary star

star cluster M-35 in order to monitor the long-term internal stability of the
FGS unit.  During these observations, the FGS acquisition at 273/010804Z
failed to FL backup on FGS-1 only.  No other anomalies were noted.

2.0 FLIGHT OPERATIONS SUMMARY:

   2.1 Guide Star Acquisitions: 

                            Scheduled Acquisitions : 23
                                        Successful : 20

       At 273/010804Z, one FGS acquisition failed to FL
       backup on FGS-1 only.  HSTAR 5309 documents this
       occurrence.

       At 273/233810, the FGS acquisition failed due to the
       scan step limit being exceeded.  This event was
       described by HSTAR 5311.

       At 274/032332Z, the acquisition failed.  The re-  
       acquisition at 274/050003Z also failed.  The 
       subsequent re-acquisition at 274/081303Z succeeded
       after the uplink of an ARU/PRT.  HSTAR 5312 describes
       these events.

                          Scheduled Reacquisitions : 24
                                        Successful : 23

       See the description of HSTAR 5312 above for this 
       failure.

   2.2 FHST Updates: 

                              Scheduled : 51
                             Successful : 51

   2.3 Operations Notes: 

       The HST operations crew attempted to conduct normal
       operations from the SAMS backup facility but, due to
       several problems, were unable to do so.  Maintenance
       will diagnose the problems encountered today.

       During operations using STGT numerous data inversions
       were encountered on all three days.  Three TTRs were
       written.

3.0 SIGNIFICANT FORTHCOMING EVENTS: 

        Nothing at this time.
