Subj:   HST REPORT #886 

       Note:
       Both the AP-5 and AP-7 computers where down with problems on the
       operational system disk. This made the ALLIN1 and MAIL functions
       inoperative on Wednesday May 12, 1993, and Thursday May 13 causing a
       delay in the distribution of the daily report via the electronic mail.

1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

   1.1 Completed Two Sets of FOS/BL 4697 (FOS Polarimetric Calibration)

       The Faint Object Spectrograph was used to make a total of 17 calibration
       observations on both the red and blue sides to obtain measurements of the
       internal Pt-Ne lamps. All seventeen observations were received and
       displayed. They were all reported to look okay. No unexpected problems
       were noticed. 

   1.2 Completed GHRS/2 3945 (G160M Spectra of Eta Car S Condensation - Cycle 2)

       The High resolution Spectrograph was used to make spectral observations
       of a gaseous knot in the southern part of the nebula Eta Carnae. In the
       first set of eleven observations, all were received and displayed. They
       were reported to look okay. There were two carrousel resets events which
       occurred, and generated status buffer error messages. The second
       carrousel reset delayed the final wavelength calibration until one
       minute after the scheduled start time of the final science
       observations. This observation did not occur. 

   1.3 Completed Two Sets of FOC/96 3801 (Search for QSOs suitable for 
       Subsequent Observations of He II)

       The Faint object Camera made ultraviolet images of five different quasars
       (2139-4434, 2050-359, 2049-353, 2038-371, and 1601+3754) to observe the
       level of their UV flux. Two recentering events occurred during two
       separate observations, and no other anomalies were noted. 

   1.4 Completed WFC 4929 (WF/PC Cycle 2: Improved Dark Calibration)

       The Wide Field Camera was used to make two dark calibrations images.
       These were pre-flashed exposures which lasted 1200 seconds each. Both
       images were received and displayed. No anomalies were noted. 

   1.5 Completed FOS/BL 4054 (Probing the Nuclear Regions of Seyfert Galaxy 
       NGC-5548)

       The Wide Field Camera was used to make observations of Seyfert galaxy
       NGC-5548 to look for time variations in its continuum, and emissions in
       Helium II and Carbon IV. The observations were executed as scheduled, and
       no problems were reported. 

   1.6 Completed WFC 4381 (HST Medium-Deep Survey Cycle 3)

       The Wide Field Camera was used to make two high latitude medium-deep sky 
       survey observations taken in parallel with the prime science
       observations. The OSS monitored the observations, and assessed the data
       quality. No problems were reported. 

2.0 FLIGHT OPERATIONS SUMMARY:

    2.1 Guide Star Acquisitions: 

                            Scheduled Acquisitions : 7
                                        Successful : 4

                          The acquisition at 132/1443Z failed to attain fine
                          lock, but did obtain course track. Three subsequent
                          reacquisitions also failed fine lock, but obtained 
                          course track.

                          Scheduled Reacquisitions : 4
                                        Successful : 4
                                    Losses of Lock : 0

   2.2 FHST Updates: 

                              Scheduled : 8
                             Successful : 8

   2.3 Significant HSTARs: None

   2.4 Operations Note: 

       The GSFC Internal Simulation (Type 1 + Replan) was conducted on
       Wednesday, May 12, and Thursday May 13.
