1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

   1.1 Completed FOS/BL 3483 (Lyman Alpha Emission in Galaxies: the Case of
       Galaxies Causing the Z = 0) 

       The Faint Object Spectrograph was used to make Lyman Alpha emission
       line observations of the galaxy PKS-1127-1 which is near the line of
       sight of a known quasi-stellar object. This galaxy is expected to
       produce Magnesium II absorption lines in the QSOs spectra. This can
       be used to confirm that star formation is taking place. Part of one 
       observation, and all of an other observation were lost because the
       Science Data Formatter was inadvertently disabled. 


   1.2 Completed Two Sets of WFC 4277 (Calibration fo Nearby Galaxy Type Ia
       Supernovae as Standard Candles) 

       The Wide Field Camera was used to make a total of three observations
       of Cepheid variable stars located inside fo galaxy NGC-5253. This is
       to help determine the accurate distance scale to this galaxy. The
       distance will be used to find the true luminosity of the type - Ia
       supernova which has been observed in this galaxy. All three 
       observations were reported to be satisfactory. 

   1.3 Completed FGS 4031 (High Speed Astrometry - A Search for Planetary 
       Companions to Low Mass)

       The Fine Guidance Sensors were used to make astrometric observations
       of the star Proxima Centauri to look for the presence of a Jupiter
       sized planet in orbit around the target star based on the position
       perturbations caused by the planet. The OSS Monitored the
       observations as possible, and no problems were reported. 

   1.4 Completed PC 3603 (Snapshot of Protoplanetary Nebulae)

       The Planetary Camera was used to make snapshot images of the
       protoplanetary system M1-92 to study its current morphology. Two
       Sets of observations were received and displayed. One observation
       was monitored in the OSS, and was reported to be okay. Two other
       observations occurred during LOS, and are on the science tape
       recorders. They will be analyzed later. 

   1.5 Completed Two Sets of GHRS/2 4067 (GHRS 1ST Order Grating spectral 
       Lamp Test)

       The High Resolution Spectrograph was used to make lamp mini-function
       wavelenght calibration observations for the first order gratings.
       This was strictly an internal test. No external sources were used.
       The observations were executed as scheduled, and no problems were
       reported. 

   1.6 Completed Two Set of FOC/96 3801 (Search for QSOs Suitable for 
       Subsequent Observation of He II)

       The Faint Object Camera was used to attempt to make observations of
       quasar QSO 0043-259 to measure the levels of its ultraviolet flux,
       to see if the flux levels are high enough for subsequent
       observations using the GHRS and FOS. These observations are
       currently on the science tape recorder and will be played back
       later. No problems have been reported. 

   1.7 Completed PC 4712 (WF/PC Cycle 2 Calibration: Measles Monitor)


       The Planetary Camera was used to make Earth Calibration Flat images
       to monitor fo a form of contamination known as measles. The
       observations used filter F517N, both with and without filter F122M.
       The OSS monitored the observation and assessed the data quality. No
       problems were reported. 

   1.8 Completed WFC/PC 4109 (WF/PC Cycle 2 Calibration: Rapid Internal 
       Monitor)

       Rapid Internal Monitoring observations were made with both the Wide
       Field Camera and the Planetary Camera using filter F555W to look for
       new forms of contamination (i.e. daises and measles), and the
       possible return of quantum efficiency hysteresis. The observations
       were monitored in the OSS, and the data quality was assessed. No
       problems were reported. 

   1.9 Completed Three Sets of FOC/96 4804 (UV Imaging of Nearby Galaxies
       With FOC/96) 

       The Faint Object Camera was used to make six ultraviolet snapshot
       images of the nearby galaxies  ESO-0220-2, UGC-1256, ESO-0044-2,
       ESO-0255-5, ESO-0306-2, and ESO-0011-2. Each exposure lasted ten
       minutes, and used filter F220W. All six images were received and
       displayed in the OSS. They all were reported to look okay. 

   1.10 Completed GHRS/2 4926 (GHRS SSA Pickup Test - Part 2)

       The High Resolution Spectrograph was used to make a calibration of
       the Small Science Aperture after a SAA peakup had been used to
       center the target.  The peakup in the SAA failed, because the proper
       commanding has not been installed. The next three observations were
       received and displayed. These observations were made with the LSA
       and were reported to look okay. 

   1.11 Uplinked Updated Ephemeris Tables, Per MOSES 2871

   1.12 Completed FOS/RD 4213 (Spectrophotometry of the Lensed "Clover
       Leaf" Broad Absorption line) 

       The Faint Object Camera was used to make four observations of the
       Lensed quasi-stellar object QSO 1413+117 (aka, the Clover Leaf). A 
       corrective maneuver was successfully calculated and uplinked to the
       spacecraft. The observations were displayed in the OSS, and they
       were reported to look okay. 

   1.13 Completed HSP/UV2 4209 (HSP Detector Sensitivity Test)

       The High Speed Photometer was used to make four calibration
       observations of standard star VID998 to determine the instruments
       long term sensitivity of the IDT detectors. All four observations
       were received and displayed. The first two observations showed the
       image of the target slightly off center. The next set of
       observations left it well centered. The following calibration images
       were reported to be good.

   2.4 Operations Note: 

       Ground Systems
       --------------

       The transition from the PORTS system to the PRS system is under way
       in the STOCC.  A successful Flight Readiness Review was conducted
       for this major installation last week.  The PRS system will be run
       in "shadow" mode for several days as a final check-out.  Benign
       ("no-op") commanding to the HST will be done using PRS after a
       successful shadow period.  The PRS system will be brought on-line as
       the primary operational system in the MOR following a successful
       transition period. 


       Fine Guidance Sensors 
       ---------------------

       FGS 2 was used for guidance on June 10 for the first time since it
       was shut down.  The acquisition was successful.  There are five FGS
       2 acquisitions scheduled during the next two weeks.  Recommissioning
       of FGS 2 will continue over the next five weeks.  At the end of this
       period the Project will assess the feasibility of returning FGS 2 to
       normal operations.
