1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

   1.1 Uplinked Updated Ephemeris Tables, Per MOSES 2871

   1.2 Completed FOS/BL 4260 ()Extreme Stellar Winds and Post Main Sequence
       Evolution)

       The Faint Object Spectrograph was used to make observations of star
       BE153. This star is believed to be intermediate between a class O
       and WR star and to have strong winds and high mass loss rate (i.e.,
       much higher than normal O class stars). Seven observations were
       received and displayed. All seven were reported to look normal.

   1.3 Completed Three Sets of WFC 4381 (HST Medium Deep Survey - Cycle 3)

       The Wide Field Camera was used to make two set of medium-deep high
       latitude sky survey observations taken in parallel with the prime
       science observations. The observations were executed as scheduled,
       and both observations were reported to look normal.

   1.4 Completed GHRS/2 4674 (Molecular Emissions in HH 47 - Cycle 3 High)

       The High Resolution Spectrograph was used to make observations of
       Herbig - Haro Object (HH47). The HRS spectrum should contain a strong
       florescence feature at 1272 A0 (Driven by Lyman - Alpha) an
       unidentified line at 1284 A0, and possibly another florescence line
       at 1293 A0. Six observations were executed in Fine Lock with no
       apparent problems. A seventh observation did not executed, and an
       HSTAR was filled.

   1.5 Completed WFC 4713 (WF/PC Cycle 2 Calibration: WFC Internal Delta
       Flats)

       The Wide Field Camera was used to make a total of five internal flat
       calibrations images. All five images were reported to be normal.

   1.6 Completed WFC 4348 (Long Period Variables of M-81 - Cycle 3 Medium)

       The Wide Field Camera was used to make two images of the galaxy M-81
       (aka, NGC-3031)  to look for long period variable stars which can be
       compared to those already studied in our own galaxy and the
       Magellanic Clouds. These stars should have period of from 100 to 100
       days. Both observations were received and displayed. One recentering
       event occurred during the first observation. Both observations were
       reported to look normal.
                                                                            
   1.7 Completed Two Sets of FGS 4938 (Parallax of Hyades Cluster Members -
       Cycle 3 High)

       The Fine Guidance Sensor #3 was used to make astrometric
       observations of the star VA-627 which is a member of the open Hyades
       star cluster. These observations are intended to determine the
       parallax of the stars and compute the distance modulus for the
       cluster. This will help improve the estimates of distances to other
       galaxies, which are base on the distance of Cepheid variable stars.
       When possible the astrometric observations were monitored by the
       OSS.

   1.8 Completed Two Sets of WFC 4848 (GTO Low Latitude Parallel Program
       Cycle 3 High)

       The Wide Field Camera was used to make two high latitude medium-deep
       sky survey observations taken in parallel with the prime science
       observations. Both observations were received and displayed. They
       were reported to look okay, and no anomalies were reported.

   1.9 Completed FGS 2565 (Linking HIPPARCOS to the Extragalactic Reference
       Frame Part 1 of 6)

       The Fine Guidance Sensors were used to make two sets of astrometric
       observations of several stars. These stars lie near the apparent
       position of extragalactic objects. These objects will also be
       observed with the HIPPARCOS satellite. The intent is to tie the
       HIPPARCOS system reference frame to the extragalactic reference
       frame. The observations were executed as scheduled. The last half of
       these observations were monitored. Scan locations 6, 8, and 11
       failed with the Search Steps Exceeded flag set.

   1.10 Completed Two Sets of FOS/BL 4059 (Absolute Photometry Monitor)

       The Faint Object Spectrograph (Blue Side) was used to make
       observations of standard star WD0501+527 to determine the absolute
       sensitivity of the FOS detectors for pipeline data calibrations. The
       first half of the observations was monitored by the OSS, and no
       anomalies were reported. The Second half of the observations
       occurred during LOS, and the data remains on the science tape
       recorder, and will be analyzed later.

   1.11 Completed WFC/PC 5026 (WF/PC Cycle 3 Calibration: Rapid Internal
       Monitor)

       The Wide Field Camera and the Planetary Camera were used to make
       internal flat calibration images. These images will be used to look
       for measles and daisies (i.e., different forms of contamination),
       and to monitor scattered light. The observations were executed as
       scheduled, and three of the four observations were reviewed in the
       OSS. The fourth observation remains on the science tape recorder.
                                                                            
  1.12 Completed PC 5073 (WF/PC Cycle 3 Calibration: PC Flats Wide. 2)

       The Planetary Camera was used to make two sets of Earth flat
       calibration images using different filter combinations. These images
       will be used for flat field corrections of science images made with
       the PC. One image was reported to be saturated, and the other was
       reported to be normal.

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

       The Planetary Camera was used to make Earth Calibration Flat images
       to monitor of 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.
       Three observations were received and displayed. Two images were
       saturated, and one looked normal.

  1.14 Completed FOS/RD/BL 4694 (Stellar Content of Galaxies and Globular
       Clusters)

       The Faint Object Spectrograph (Both the Red and Blue Sides) were
       used to make observations of globular cluster K280 which is located
       in the M-31 Galaxy (aka, Andromeda Galaxy). The G130H grating was
       used of the Blue side, and G270H and G400H were used on the Red
       Side. The observations contained nothing but noise because of a Loss
       of Lock (See Operations Note 2.1) An HSTAR was filed.

  1.15 Completed Four Sets of WFC 5013 (WF/PC Cycle 3 Calibration: WFC
       Flats Narrow. 2)

       The Wide Field Camera was used to make Earth flat calibration images
       to be used for flat fielding of WFC observations. The observations
       used the narrow band filters, both with and without neutral density
       filters. A total of eight observations were received. Four
       observation was reported to be saturated, and the other four were
       okay.

  1.16 Completed HSP/UV2 3798 (A search for Radial Pulsations in White
       Dwarfs)

       The High Speed Photometer was used to make ultraviolet observations
       of the white dwarf star G130-5 to look for predicted radial
       pulsations. Three sets of observations were monitored and displayed.
       The onboard target acquisition was successful. The photometric
       observations were reported to look normal.

  1.17 Completed FOC/96 4846 (High Resolution Observations of Cataclysmic
       Variables - Cycle 3 High)

       The Faint Object Camera was used to make one image of the
       cataclysmic variable star Center-A-B which is suspected to have a
       complex region of nebulosity surrounding it. The observation was
       received and displayed. No anomalies were noted.

  1.18 Completed WFC 4849 (GTO High Latitude Parallel Program - Cycle 3
       High)

       The Wide Field Camera was used to make high latitude sky survey
       observations taken in parallel with the prime science observations.
       The observations were executed as planned. Two image were received
       and displayed. No anomalies were reported.

  1.19 Completed PC 5014 (WF/PC Cycle 3 Calibration: PC Flats Narrow. 2)

       The Planetary Camera was used to make standard Earth calibrations
       images for flat fielding of PC observations. Medium and narrow
       filters were used, with and without neutral density filters. The
       observations were executed as scheduled. Two observations were
       received and displayed. One was saturated, and the other was
       reported to look okay.
