   1.4 Completed FOS/BL 4396 (QSO Absorption Systems Snapshot Survey - Part
       1 of 3: Cycle 3 High) 

       The Faint Object Spectrograph (Red Side) was used to make one
       spectrographic observation of quasar 0253-0138 to look for
       absorption line systems at low red shift, emission lines, and to
       study the QSO's continuum. The observation was executed as 
       scheduled, and no problems were reported.

   1.5 Completed Two Set of 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, and the observations were
       reported to look satisfactory. 

   1.6 Completed GHRS/2 3845 (Deciphering the UV Emission Lines in T Tauri 
       Systems)

       The High Resolution Spectrograph was used to make six ultraviolet
       spectral observations of the T-Tauri class star BP-Tauri to study
       the width and shape of its emission lines which will put constraints
       on the type of mechanism producing these lines. One wavelength
       calibrations and six spectral observations were received and
       displayed. No problems were reported 

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

       The Planetary Camera was used to make two dark calibration images.
       The two exposures lasted 1200 seconds each, and the camera was
       pre-flashed before the observations. Both observations were reported
       to be normal exposures. 

   1.8 Completed Two Sets of FOS/BL 4203 (Spatially Resolved Spectroscopy 
       of Jupiter - Cycle 2/ April - May 1993) 

       The Faint Object Spectrograph was used to make ultraviolet spectral
       observations of Jupiter's moon IO to make an "image spectrum" which
       was used to determine the position adjustment needed to center
       the spectrum of subsequent observations of Jupiter's red Spot and
       the North Pole Region. A corrective maneuver was successfully
       uplinked to the spacecraft. Io was reported to be well centered.
       Subsequent observations of Jupiter showed the Red Spot Near the limb
       of the Planet. The spectral observations looked fine. 

   1.9 Uplinked Updated Ephemris Tables, Per MOSES 2871 

   1.10 Completed Two Sets of PC 4809 (Cycle 2: WF/PC PSF Calibration 
        Proposal)

       The Planetary Camera was used to make point spread function
       calibration image of standard star HD151406. The OSS monitored the
       observations and assessed the data quality. The last observations
       was reported to have been taken at an incorrect pointing location. 

   1.11 Completed GHRS/2 4601 (Jupiter's hydrogen Lyman Alpha Auroral/ 
        Airglow Line Profile - Cycle 3 High)

        The High Resolution Spectrograph was used to make observations of
        the Hydrogen I emission line at 1216 A0 from Jupiter's atmosphere
        at latitudes of +40, +50, +55, +60 and +70 degrees along the
        central meridian. The observations were executed as scheduled, and
        no problems were reported. 

   1.12 Completed FOS/RD 5050 (Cycle 3 Internal Wavelenght Calibration)

        The Faint Object Spectrograph was used to make calibration spectra
        for every detector/ grating combination through the 0.3" circular
        and 0.1" paired apertures. The observations were monitored in the
        OSS, and the data quality was assessed. No problems were reported. 

   1.13 Completed FOS/RD 4881 (Spect. Studies of Several High Z BAL-QSOs: 
         Cycle 3 Medium)

        The Faint Object Spectrograph was used to make one observation of a
        broad absorption line quasar (Type BAL-QSO) known as Q1408+5642 as
        part of a survey of the ultraviolet spectra of these objects. The
        binary target acquisition failed because there was not enough
        counts in any of the read-out steps. The data was examined, and
        only noise was seen. The target apparently was not in the field of
        view. An HSTAR was filed. 

   1.14 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, and no problems were
       reported. 

   1.15 Completed FOS/RD 4581 (Quasar Absorption Line Survey - Cycle 3
        High) 

       The Faint Object Spectrograph (Red Side) was used to make two
       observations of quasar Q1224-1116 to learn more about the origin and
       evolution of gas clouds along the line of sight of this target. Both
       observations were received and displayed. They had only noise, as was
       expected for this observations. No other anomalies were noted. 

   1.16 Completed FGS 4935 (Parallaxes of Hyades Cluster Members - Cycle 3 
        High) 

       The Fine Guidance Sensors were used to make astrometric observations
       of star VA276 which is located in the Hyades cluster to obtain a
       definitive calibration of its  population I zero-age main sequence
       members. The observation appeared to execute with no problems 

   1.17 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. 

   1.18 Completed FOS/BL 3441 (Post Asymptotic Giant Branch Evolution in
        the Magellanic Clouds) 

       The Faint Object Spectrograph was used to make two spectral
       observations of the planetary nebula LMC-SMP-87 which is located in
       the Large Magellanic Cloud. Both observations were received and
       displayed. The onboard target acquisition was successful, and the
       subsequent confirmation image showed that the target was well
       centered. 

   1.19 Completed 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. Both observations were received and displayed,
       and no problems were reported. 

   1.20 Completed FOS/RD/BL 4976 (UV Rotation Light Curves for Pluto, and
        Charon's UV Spectrum - Split) 

       The Faint object Spectrograph was used to make a TALED exposure
       subsequent to other spectral observations of the planet Pluto and
       its moon Charon. The TALED observation was received in real time. It
       was reported to look okay. After a corrective SIP maneuver was
       successfully uplinked to the spacecraft, spectral observations were
       made of the planet Pluto. The observations were executed in fine
       lock. No problems were reported. 

   1.21 Completed Two Sets of GHRS/2 5039 (GHRS Dark Noise Monitoring 0 
        Cycle 3)

       The High Resolution Spectrograph was used to make twelve dark
       calibration images. The photoscan mode was used with an integration
       time of 10 seconds and with seven bins, for a read-out every 70
       seconds. There was no carrousel motion. Observations were taken both
       inside and outside the small science aperture. All twelve
       observations were received and displayed. No anomalies were
       reported. 

   1.22 Completed FOS/RD 4953 (QSO Absorption System Snapshot Survey - Part
        3 of 3: cycle 3 High) 

       The Faint Object Spectrograph was used to make observations of
       quasar 2440+3539 to look for absorption lines at low redshift, and
       also emission lines in the QSO's continuum. The observations were
       executed as scheduled, and no problems were reported. 

   1.23 Completed FOS/BL 4600 (FUV Spectroscopy of Io's SO2 Atmosphere and 
        Surface - Cycle 3 Medium) 
 
       The Faint Object Spectrograph (Blue Side) was used to make spectral
       observations of the bright and dark regions on the surface of
       Jupiter's moon Io. A scan across Io was also made. The objective of
       this proposal was to further characterize the behavior fo SO2 in
       Io's atmosphere. The observations were not received in real-time.
       The analysis and offset links for this proposal were impacted by
       loss of the TDRS East satellite. The observations were received by
       the science tape recorder playback. After communications were
       re-established, several corrective maneuvers were uplinked to the
       spacecraft. Many of the following observations were reported to look
       satisfactory. One spectral observation was reported to have an noisy
       diode on channel 139. 

   1.24 Completed GHRS/2 5036 (GHRS 1ST Order Grating Spectral Lamp Test - 
        Cycle 3)

       The High Resolution Spectrograph was used to maker eight
       spectral mini function calibration lamp tests of the first order
       gratings. All eight observations were received and displayed. in the
       OSS. No anomalies were noted.
