PERIOD COVERED:  0800 EST
Daily Status Report as of 159/1200Z.

1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

   1.1 Completed WFC 5010 (Determination of the Extragalactic distance 
       Scale. III. M-101)

       The Wide Field Camera was used to make two images of the large Sc
       class spiral galaxy NGC-5457 in Ursa Major (aka, M-101) to look for
       Cepheid variable stars. Both images were received and displayed in
       the OSS. They both were reported to look okay. 

   1.2 Completed FOC/96 4804 (Ultraviolet Imaging of Nearby Galaxies FOC/96)

       The Faint Object Camera (f/96) was used to make one ultraviolet
       snapshot image of nearby galaxy UGC-3522. The exposure lasted ten
       minutes, and used filter F220W. The observations was received and
       displayed. It was reported to look okay. 

   1.3 Completed PC 3982 (Physical conditions in the Narrow - Lined Region)

       The Planetary Camera was used to make six observations of the active
       galactic region of Seyfert galaxy NGC-3393 to learn more about the
       structure of its nucleus. The first four observations were received
       and displayed in real time. They were reported to be okay. The last
       two observations occurred during LOS, and are still of the science
       tape recorder. They will be analyzed later. 

   1.4 Completed GHRS/2 4927 (GHRS SSA Peakup test - Part 1)

       The High Resolution Spectrograph was used to conduct a Small Science
       Aperture Peakup Test. The test involved using the
       return-to-brightnest algorithm with a small spiral search. The test
       consisted of a Large Science aperture onboard acquisition on Chi
       Lupi (aka,BD 75D325), a spectrum take in the Large Science Aperture
       to define the stellar flux, a slew to the Small Science Aperture
       followed by a new Peakup, and a mapping of the Small Science
       Aperture. The observations were executed as scheduled, and no
       problems were reported. 

2.0 FLIGHT OPERATIONS SUMMARY:

    2.1 Guide Star Acquisitions: 

                            Scheduled Acquisitions : 4
                                        Successful : 4
                          Scheduled Reacquisitions : 10
                                        Successful : 10
                                    Losses of Lock : 0

   2.2 FHST Updates: 

                              Scheduled : 10
                             Successful : 10

   2.3 Significant HSTARs: None

   2.4 Operations Note: 

       A simulation of EVAs 1 and 2 were successfully conducted yesterday
       (Tuesday, June 7) with 24 TSARs being generated. Major simulated
       anomalies included the RSU2 gyros failing to power on and a SDM SA
       retraction failure. Each of these cases were referred to a
       management tiger team which recommended recovery scenarios. A
       debriefing will be conducted today at 3:00 P.M.
