PERIOD COVERED:  0800 EST
Daily Status Report as of 070/1200Z.

1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

   1.1 Completed FOS/BL 3538 ( UV spectra of Extended Emission Regions 
       Around QSOs)

       The Faint Object Spectrograph (Blue Side) was used to make a set of
       four observations of quasi-stellar object B2-1512+37 to obtain
       spectra of the extended emission line region around the quasar. All
       four observations were received and displayed. The first was the
       binary target acquisition (eight groups), the second was the
       confirmation image, and the last two were the scientific spectral
       observations. The target was well centered in the 4.3 arcsecond
       aperture. The spectral observations were reported to be weak and
       noisy, but showed some signs of emission lines at the expected wave
       lengths. The third observations was filed as being bad because of
       high jitter during a night/day transition. 

   1.2 Completed Two Sets of S/C/FOS/BL 4099 (FOS focus, X-Pitch and
       Y-Pitch) 

       The Faint Object Spectrograph was used to make two sets (of seven
       observations each) as part of the focus and x/y pitch test. All
       fourteen observations were received and displayed. They were
       reported to be okay. 
 
   1.3 Completed FOC/96 4800 (Stellar content of Wolf-Rayet Galaxies)

       The Faint Object Camera (f/96) was used to make one image of the
       Wolf-Rayet Galaxy NGC-1741. The star burst galaxy is know to exhibit
       broad He II emission lines from stellar sources. The observations
       was executed without problems. The data was received and displayed.
       There was roll-over in the central pixel for some of the brightest
       objects, and the data looked good. 

   1.4 Completed WFC 4658 (Determination of Extragalactic Distance Scale)

       An attempt was made to use the Wide Field Camera to make
       observations of NGC-5457 (aka, M-101, a large spiral galaxy in Ursa
       Major). The baseline guide star acquisition failed , because
       the FHST update preceding it corrected only for roll, and not for
       v2-v3 error. The subsequent reacquisition was executed with out
       problems and it was received and was displayed. The first image was
       empty, and the second was filled with stars and cosmic ray hits. 

   1.5 Completed GHRS/2 3626 (Ephemeral Determination fo wind Velocities and 
       Density Laws)

       The High Resolution Spectrograph was used to make a series of eight
       observations of the star Zeta Aurigae (aka, HD32068). The onboard
       spiral search, and the peakup were successful. The wave length
       calibrations, and the Echelle-B spectral observations were executed
       without problems. 

   1.6 Completed PC 4140 (WF/PC Calibration: Rapid Internal Monitor Part 2)

       The Planetary Camera was used to make internal flat observations to
       check for new forms of contamination, and the reappearance of
       quantum efficiency hysteresis (QEH). The observations were executed
       as scheduled, and no problems were reported. 

   1.7 Completed Uplink Updated Ephemeris Tables, Per MOSES 2871

   1.8 Completed GHRS/2 3496 (Ultraviolet Atlas of Sirius)

       The High Resolution spectrograph was used to obtain ultraviolet
       spectra of the star Sirius (aka, HD48915) in the WSCAN Mode to get
       an accurate measurements of its flux distribution and line profiles.
       The observations were executed as scheduled. There was an acquisition 
       failure at 070/0807Z and a reacquisition failure at 070/0943Z. The
       observations were filed as bad. 

   1.9 Initiated FOC/96 3591 (Massive Stars in Starburst galaxies - FOC
       Images) 

       The Faint Object Camera was used to initiate ultraviolet images of
       the star bursting galaxy IZW18. The observations are currently under
       way, and will be analyzed later.

                             the threshold.)
