PERIOD COVERED:  0000Z (UTC) 06/29/99 - 0000Z (UTC) 06/30/99

Daily Status Report as of 181/0000Z

1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

   1.1 Completed WF/PC-2 6346 (Snapshot Survey of the Ultraluminous IRAS Galaxy
Sample-Part 1 High)

       The WF/PC-2 was used to make snapshot survey observations of the
ultraluminous IRAS galaxy QDOTULIR01.  These data will be searched for multiple
cores, which imply a merger has occurred, and for starburst regions.  The
observations were executed as scheduled, and no anomalies were noted.

   1.2 Completed 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.  

   1.3 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.  

   1.4 Completed WF/PC-2 6357 (The Nuclear Morphology of Elliptical Galaxies)

       The WF/PC-2 was used to make images of the early type, large, elliptical
galaxy NGC-3193 (taken from a list of 150 galaxies) in order to study its
nuclear morphology.  This survey will complement Illingworth’s snapshot study
of later Hubble types.  The observations were completed as scheduled, and no
anomalies were reported. 

   1.5 Completed Nine 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 high
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 acquisition for the fifth iteration of this proposal
failed and the take data flag remained down.  Otherwise, the observations were
completed as scheduled, and no further anomalies were reported.  

   1.6 Completed Two Sets of WF/PC-2 6967 (Blue Continuum Snapshots of 3CR
Radio - Continued Galaxies)

       The WF/PC-2 was used to make observations of the radio galaxies 3C256.0
and 3C379.1.  Radio galaxies are an important class of extragalactic objects:
they represent one of the most energetic astrophysical phenomena and they may
be used as probes of their environments.  They are unique probes of the early
Universe.  The observations were completed as planned, and no problems were
reported.  

   1.7 Completed STIS/CCD/MA1 8027 (Star-formation Knots in Distant Galaxies)

       The Space Telescope Imaging Spectrograph (CCD and MA1) were used to make
long slit spectra observations of the star formation knots in the distant
merging galaxy NGC-4038.  Ultraviolet and visible images were obtained.  A
wavelength calibration observation was also taken.  The observations were
completed as planned and no anomalies were reported.  

   1.8 Completed WF/PC-2 8090 (POMS Test Proposal: WF-II Parallel Archive
Proposal Continuation)

       The WF/PC-2 was used in the parallel mode to make some low galactic
latitude archive observations.  The program will be used to take parallel
images of random areas of the sky.  The observations were executed as
scheduled, and no anomalies were noted.  

   1.9 Completed Two Sets of WF/PC-2 8445 (WF/PC-2 Cycle 8 Earth Flats)

       The WF/PC-2 was used to make Cycle 8 Earth flat calibration
observations.  This is to obtain sequences of earth streak flats to construct
high quality flat fields for the WF/PC-2 filter set.  The observations were
executed as scheduled, and no anomalies were noted.  

   1.10 Completed STIS/CCD/MA1 8015 (Properties of the Lyman-Alpha Forest and
Metal-Line Systems at Low Z)

       The Space Telescope Imaging Spectrograph (CCD and MA1) were used to make
observations of the Lyman-Alpha forest and the Metal line systems in radio
galaxy 3C351.  This program seeks to learn more about the properties of
metal-line systems and the Lyman-alpha forest at low redshifts.  A wavelength
calibration image was also taken.  The observations were executed as scheduled
and no anomalies were noted.  

   1.11 Completed WF/PC-2 6347 (A Search for Jets in Planetary Nebulae)

       The WF/PC-2 was used to make observations of the planetary nebulae
(class PNe) PK055+02D2 and PK032+07D2  in order to search for the presence of
possible narrow jets.  The current model for PNe formation indicates that jets
are an unexpected phenomena, yet there is a growing body of circumstantial
evidence that suggests narrow jets are common feature in PNe.  The observations
were completed as scheduled, and no anomalies were noted.

   1.12 Completed STIS/CCD/MA1/MA2 8078 (Ultra-Hot Nuclei and Their Surrounding
Planetary Nebulae)

       The Space Telescope Imaging Spectrograph (CCD, MA1 and MA2) was used to
make observations of the ultra-hot nuclear region of planetary nebula
NGC-6905.  Ultraviolet and optical spectra of hot pre-white dwarfs and white
dwarfs, often in planetary nebulae, show emission from ions characterizing
temperatures far above that of the photosphere.  A wavelength calibration image
was also taken.  The observations were executed as scheduled, and no anomalies
were noted.  

   1.13 Completed WF/PC-2 6362 (Supernova Host Galaxy)

       The WF/PC-2 was to be used to make observations of the supernova host
galaxies GAL-111610, NGC-289 and ESO404G3.  The acquisition for this proposal
failed and the take data flag remained down, affecting two observations.

   1.14 Completed WF/PC-2 6360 (A Snapshot Survey of “Radio Loud” IRAS
Galaxies)

       The WF/PC-2 was used to make snapshot survey observations of the radio
loud IRAS galaxy GAL-2151-2.  The WF/PC-2 was used to discern high surface
brightness structures in its post-starburst active nuclear regions.  The
observations were completed as scheduled, and no anomalies were reported.

   1.15 Completed FOC/96 6349 (Snapshot Search for High Redshift QSOs with
Far-UV Flux)

       The Faint Object Camera (f/96) was used to make snapshot images of the
quasi-stellar object Q0057-274.  This is to determine if this high redshifted
object has a far ultraviolet flux.  The observations were executed as
scheduled, and no anomalies were noted.

2.0 FLIGHT OPERATIONS SUMMARY:

   2.1 Guide Star Acquisitions: 

                            Scheduled Acquisitions : 13
                                        Successful : 12

       As described in HSTAR 7186, the acquisition scheduled for 180/191816Z
failed to RGA control when FGS-1 exceeded the scan step limit.  The proposals
detailed in 1.5 and 1.13 were affected.

                          Scheduled Reacquisitions : 2
                                        Successful : 2

   2.2 FHST Updates:

                             Successful : 27

   2.3 Operations Notes: 

       Using ROP SR-1, the SSR EDAC error counter was cleared once.

       The FHST map at 180/1520Z found no stars in FHST-2.  HSTAR 7185 was
written.

3.0 SIGNIFICANT FORTHCOMING EVENTS:
