Daily Status Report as of 039/1200Z.

1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

   1.1 Completed GHRS/2 1160 (Absorption Cl. Phys. in Seyfert Galactic 
       Nuclei)

       The High resolution Spectrograph was used to make fifteen
       observations of the nucleus of Seyfert galaxy NGC-3783. All fifteen
       observations were reported to look okay. 

   1.2 Completed GHRS/2 4012 (Dark Count Statistics for GHRS Detectors)

       The High Resolution Spectrograph was used to make one dark
       observations for a special investigation of the number 2 detector.
       The single observation was received and displayed, and was reported
       to look okay. 

   1.3 Completed Two Sets of GHRS/2 3614 (Boron as a Probe of Stellar 
       Structure)

       The High Resolution Spectrograph was used to make Boron line studies
       of the star HD26462 to study the star's interior. The guide star
       acquisition failed. MOSES uplinked an Attitude Reference Update and
       the reacquisition was successful. An HSTAR was written. An HSTAR was
       also written for a carousel reset error that was received prior to
       the first observation. The second set of science observations were
       received and were reported to look "pretty good", but it is not sure
       if the target was well centered in the aperture. 

   1.4 Completed WFC/PC 4109 (WF/PC Calibration: Rapid Internal Monitor)

       Both the Wide Field Camera and the Planetary Camera were used to
       take two internal flat observations using filter F555W looking for
       daisies and measles (i.e., new form of contamination). Both to the
       observations were reported to be okay. 

   1.5 Completed PC 3230 (PC PSF and Focus Monitoring 2)

       The Planetary Camera was used to make one image of the point spread
       function and to test the system focus by making an observation of
       quasar SAO55685. The image was reported to have fallen on the Baum
       Spot. 

   1.6 Completed HSP/UV1 4247 (UV Observations of Geminga)

       The High Speed Photometer was used to make an ultraviolet study the
       optical counterpart of the gamma ray source Geminga (aka,
       GSC55685-0). The object was reported to be well centered, but
       exceedingly faint, as was expected. 

   1.7 Completed Two Sets of WFC/PC 3172 (WF/PC SV Observations: Internal 
       Monitor Proposal)

       Both the Wide Field Camera and the Planetary Camera were used to
       take a series of dark, internal flat, and KSPOT images to be used in
       the calibration of the camera. All observations were reported to be
       normal calibration exposures. 

   1.8 Completed PC 4347 (WF/PC Calibration: Flood Retention Test)

       The  Planetary camera was used to that three Earth flat observations
       using filter F439W to determine how much of the last ultraviolet
       flood retention test still remains. All three observations were
       received and displayed. The first image was underexposed, and the
       last two were overexposed. 

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

       The Planetary Camera was used to obtain Earth flats 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). Three image were received and displayed. The first
       image was underexposed, and the other two were reported to be okay. 

   1.10 Completed GHRS/2 3626 (Ephemeral Deter. of Wind Velocity and Density)

       The High Resolution Spectrograph was used to make thirteen spectral
       observations of the eclipsing binary star Zeta Aurigae (aka,
       HD32068). All of the calibration images and science spectral
       observations were reported to be okay. 

   1.11 Completed GHRS/2 3737 (the Onset of Chromospheric Activity)

       The High Resolution Spectrograph was used to make four spectral
       observations of the area around the carbon II resonance lines at
       1335 A0 on A class star HD165040. All four observations were
       executed without problems. The science data was reported to be very
       noisy, and possibly underexposed. 

   1.12 Completed FOS/BL 3268 (UV Spectra of QSOs with Z > 3.1 Observations)

       The Faint Object Spectrograph was used to make three ultraviolet
       spectral observations  of high red shifted quasar 1334-005. All
       three observations were executed without problems, and the science
       data was reported to be okay. 

   1.13 Completed WFC 1297 (GTO High Latitude Parallel Program)

       The Wide Field Camera was used to take two high latitude images
       which were taken in parallel with the prime science observations.
       The images were reported to look okay. 

   1.14 Completed GHRS/2 3934 (Physical Conditions and Velocity Structures)

       The High Resolution Spectrograph was used to make spectral
       observations of hot red giant binary star CI Cygni. The base line
       guide star acquisition failed coarse track. A HSTAR was written. The
       subsequent two reacquisitions also failed. The subsequent science
       observations were reported as being lost. Later a third
       reacquisition was successful. There were no observations made after
       this, since the HRS schedule to stop observing was less than 15
       minutes after the reacquisition. 

   1.15 Completed FOS/RD 3840 ( Abundances and Evolution of  Carbon 
        Nitrogen and Oxygen)

       The Faint Object Spectrograph was used to make ultraviolet spectra
       of the extra galactic hydrogen II region T1214-277 looking for the
       abundances of carbon, nitrogen, and oxygen. The observations were
       executed as scheduled, and no problems were reported. 

   1.16 Completed WFC 3917 (HST Medium Deep Survey Part 1)

       The Wide Field Camera was used to take a series of high latitude
       survey images which were taken in parallel with the prime science
       observations. The observations were executed as scheduled, and no
       problems were reported. 

   1.17 Completed FGS 2941 (High Speed Astrometry Search for Planet 
        Companions)

       The FGSs were used to make astrometric observations of Barnard's
       star looking for the presence of a Jupiter sized planet. The
       observations were monitored in the OSS, and no problems were
       reported. 

   1.18 Completed FOC 3790 (Polarization Imaging of Radio Galaxies)

       The Faint Object Camera (f/96)was used to make three ultraviolet
       polarization image of radio galaxy 3C321. All three images were
       received and displayed in the OSS. They were reported to look okay. 

   1.18 Completed FOC/96 3801 (QSOs Suitable for Subsequent Observations)

       The Faint Object Camera (f/96) was used to make one image of quasar
       1640+4628 to measure its ultraviolet flux level to see if it has
       sufficient flux to be observed in future observations using the GHRS
       and FOS. 

   1.20 Completed PC 3603 (Snapshot of Protoplanetary Nebulae)

       The Planetary Camera was used to take one image of the
       protoplanetary system HE3-1475. The observation was taken during
       LOS, and still remains on the science tape recorder. It will be
       analyzed later. 

   1.21 Initiated FOC/96 3487 (Cooling Flows in Distant Clusters)

       The Faint Object Camera (f/96) is currently being used to make
       observations of the star formation region in galaxy NGC-5920. The
       observations are currently on-going, and will be analyzed later.
