1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

   1.1 Uplinked Updated Ephemeris Tables, Per Moses 2871

   1.2 Completed HSP/POL 4888 (Remnant Stars in Supernova Remnants)

       The High Speed Photometer was used to make a series of observations
       of a unusual remnant star SS433 from a supernova which has emission
       lines that vary in velocity by a relativistic amount in a 162 day
       cycle. All of the observations were reported to be satisfactory. 

   1.3 Completed WFC 4770 (WF/PC Cycle 2 Calibration: Internal Monitor 
       Proposal)

       The Wide Field Camera was used to make routine calibration bias,
       internal flat, and dark images. The dark images were reported to
       look okay, the internal flat images has saturated in the corners,
       and the bias observations were normal. 

   1.4 Completed PC 3603 (Snapshots of Protoplanetary Nebulae)

       The Planetary Camera was used to make one snapshot image the the
       protoplanetary system W-Aquilai to study its current morphology. The
       observations was received and displayed in the OSS. It was reported
       to look okay. 

   1.5 Completed PC & FOC/96 5009 (ST Focus Investigation)

       Both the Planetary Camera and the Faint Object Camera were used to
       make a large number of images of several stars to determine how the
       focus changes with orbital phase. All observations went very well. A
       SIP corrective maneuver was successfully uplinked to center the
       target in the aperture for one of the observations. (See Notes 1.6
       and 2.4). 

   1.6 Completed FGS 5011 (Astrometry for ST Focus Investigation)

       The Fine Guidance Sensors were used to make astrometric observations
       to support the "breathing test". The astrometric observations were
       monitored in the OSS. No problems were seen. (See Notes 1.5 and
       2.4). 

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

       The Faint Object Spectrograph was used to make one observations of
       the nuclear regions of Seyfert galaxy NGC-5548 looking for time
       variability in its continuum fluxes, and emissions in Helium II and
       Carbon IV. The observations was monitored in the OSS. The spectrum
       was reported to look fine, with reasonable counts. 

   1.8 Completed WFC 4381 (HST Medium - deep Survey  - Cycle 3)

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

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

       The Planetary Camera was used to make Earth flat images using filter
       F517N, both with and without filter F122M. This is to monitor the
       appearance and number of measles (i.e., a form of contamination).
       The observations were executed as scheduled, and no problems were
       reported. 

   1.10 Completed WFC/PC 4109 (WF/PC cycle 2 Calibration: Rapid Internal 
        Monitor)

       Both the Planetary Camera and the Wide Field Camera were used with
       filter F555W to make internal flat observations to check for new
       forms of contamination (i.e., daisies and measles), and the return
       of quantum efficiency hysteresis. The OSS conducted routine
       monitoring. No problems were reported. 

   1.11 Completed FOS BL 3616 (The Upper Atmosphere of Uranus and Neptune) 

       The Faint Object Spectrograph was used to make far ultraviolet
       spectral observations of the upper atmosphere of Neptune to look for
       molecular hydrogen emissions. An onboard target acquisition was
       successfully performed on Neptune's moon Trition, and the telescope
       was offset to the planet. The OSS monitored the observations, and no
       problems were reported. 

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

       The Wide Field Camera was used to make one 1200 second long internal
       dark exposure. The camera was preflashed before the exposure. No
       problems were reported.

   2.4 Operations Note: 

       The Breathing Test was executed on the spacecraft on May 25-26.
       Preliminary indicators are that the test proceeded as planned. There
       were sessions of two data takes each. Each session included guide
       star acquisitions using fine lock, followed by parallel data takes
       involving FGS #2 as the astrometry FGS, and images from the FOC and
       WF/PC. Data analysis is now under way. (See Notes 1.5 and 1.6)
