PERIOD COVERED:  0000Z (UTC) 08/30/99 - 0000Z (UTC) 08/31/99

Daily Status Report as of 243/0000Z

1.0 OBSERVATIONS SCHEDULED AND ACCOMPLISHED:

   1.1 Completed Three Sets of WF/PC-2 8442 (WF/PC-2 Cycle 8 Standard Darks)

       The WF/PC-2 was used to make a series of Cycle 8 standard dark
calibration observations.  This dark calibration program obtains dark frames
every week in order to provide data for the ongoing calibration of the CCD dark
current rate, and to monitor and characterize the evolution of hot pixels.  The
observations were executed as scheduled, and no anomalies were noted.  

   1.2 Completed Three Sets of STIS/CCD 8202 (Bright Quasar Close Lensing
Search)
20>
       The Space Telescope Imaging Spectrograph (CCD) was used to make
observations of HCLQ0317-5, HCLQ0350-5 and HCLQ 0334-5 as part of a second
generation survey to search for bright lensing quasars.  With the restored PSF,
new images will be considerably more sensitive to the presence of both close
separation and faint lens components, and because STIS reaches two magnitudes
fainter the PC, the new snapshot images will have much greater dynamic range. 
The observations were executed as scheduled, and no anomalies were noted.  

   1.3 Completed Two Sets of WF/PC-2 8243 (SINS: The Supernova Intensive Study
- Cycle 8)

       The WF/PC-2 was used to make observations of supernova LMC-SN1987. 
Supernovae reveal the last stages of stellar evolution, create the chemical
history of the Universe, energize the interstellar gas, and occupy the center
of attention for the extragalactic distance scale and cosmology.  A wavelength
calibration image was also taken.  The observations were completed as planned,
and no problems were reported.  

   1.4 Completed Two Sets of WF/PC-2 8443 (WF/PC-2 Cycle-8 Supplemental Darks
pt1/3)

       The WF/PC-2 was used to obtain three dark frames every day to provide
data for monitoring and characterizing the evolution of hot pixels.  The
observations were completed as planned, and no problems were reported.  

   1.5 Completed STIS/CCD 8409 (STIS CCD Bias Monitor C8)

       The Space Telescope Imaging Spectrograph (CCD) was used to make a CCD
bias calibration observation.  This is to monitor the bias in the 1x1, 1x2,
2x1, and 2x2 bin settings at gain=1, and 1x1 at gain = 4, to build up high-S/N
superbiases and to track the evolution of hot columns.  The observations were
executed as scheduled, and no anomalies were reported.  

   1.6 Completed Two Sets of STIS/CCD 8408 (STIS CCD Dark Monitor C8)

       The Space Telescope Imaging Spectrograph (CCD) was used to make a CCD
bias calibration observation.  This is to monitor the darks for the STIS CCD. 
The observations were executed as scheduled, and no anomalies were reported.  

   1.7 Completed WF/PC-2 6701 (Photometry of the Globular Cluster System of the
Sagittarius Dwarf Galaxy)

       The WF/PC-2 was used to make observations of the globular cluster system
which is located the Sagittarius Dwarf Galaxy Gal-185503.  Isochrone fits to
these data will yield the accurate age of this system.  The observations were
completed as scheduled, and no anomalies were reported. 

   1.8 Completed STIS/CCD 8412 (STIS CCD Imaging Flats C8)

       The Space Telescope Imaging Spectrograph (CCD) was used to investigate
the flat-field stability of the unit over a monthly period.  A bias calibration
observation was also taken.  The observations were executed as scheduled, and
no anomalies were noted.

   1.9 Completed STIS/CCD 8411 (STIS CCD Spectroscopic Flats C-8)

       The Space Telescope Imaging Spectrograph (CCD) was used to obtain CCD
flats in the spectroscopic mode.  The observations were completed as scheduled,
and no anomalies were reported.  

   1.10 Completed Four Sets of STIS/CCD 8406 (POMS Test Proposal: STIS
Non-Scripted Parallel Proposal Continuation V)

       The Space Telescope Imaging Spectrograph (CCD) was used to make low
galactic latitude observations taken in parallel with the prime science
observations as part of a POMS proposal.  This is a STIS non-scripted parallel
Condition V proposal.  The observations were completed as scheduled, and no
anomalies were reported.  

   1.11 Completed Three Sets of WF/PC-2 8457 (UV Earthflats)

       The WF/PC-2 was used to make a ultraviolet Earth flat calibration
image.  This is to improve the quality of pipeline the ultraviolet flatfields. 
The observations were completed as scheduled, and no problems were reported.  

   1.12 Completed STIS/MA1 8201 (Ultra-luminous Infrared Galaxies)

       The Space Telescope Imaging Spectrograph (MA1) was used to make
ultraviolet observations of the ultra-luminous infrared galaxy IRAS19254. 
Ultra-luminous Infrared Galaxies are the most luminous galaxies known in the
local universe, and are predominantly powered by massive star formation.  The
observations were executed as scheduled, and no anomalies were noted.
