PERIOD COVERED:  0000Z (UTC) 03/07/00 - 0000Z (UTC) 03/08/00

Daily Status Report as of 068/0000Z

1.0 OBSERVATIONS SCHEDULED AND ACCOMPLISHED:

    1.1 Completed WF/PC-2 8216 (T Tauri Star Snapshot Survey II. Completing 
the CTTs Sample)

        The WF/PC-2 was used to make observations of the T-Tauri class star 
known as WSB-28 as part of Snapshot Survey II.  This database will be of 
fundamental importance to understanding the nature of planet-forming 
environments and their frequency in the galaxy.  The observations were 
executed as scheduled, and no anomalies were noted.

    1.2 Completed STIS/CCD 8439 (Bias Monitor-Part 2 C8)

        The Space Telescope Imaging Spectrograph (CCD) was used 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 track the evolution of hot 
columns.  The proposal completed with no reported problems.

    1.3 Completed Three Sets of WF/PC-2 8460 (Cycle 8 Supplemental Darks pt2/3)

        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 completed with no reported problems.

    1.4  Completed Two Sets of STIS/CCD 8437 (Dark Monitor-Part 2 C8)

        The Space Telescope Imaging Spectrograph (CCD) was used to monitor 
the darks.  The proposal completed nominally.

    1.5 Completed WF/PC-2 8230 (Snapshot Survey of Dynamically Close Galaxy 
Pairs from z=0.1 to z=0.5)

        The WF/PC-2 was used to make snapshot survey observations of 
galactic cluster Gal-Clus-0.  This is to obtain snapshot images of a large, 
well-defined, and dynamically selected sample of close galaxy pairs at 
moderate redshift.  The observations were executed as scheduled, and no 
anomalies were noted.

    1.7 Completed Six Sets of 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.

    1.8 Completed STIS/CCD 8299 (Mapping the Dynamics of the Quasar 3C 48)

        The Space Telescope Imaging Spectrograph (CCD) was used to 
determine the relation between the properties of the radio source and those 
of the {optical} line-emitting gas in quasars and radio galaxies.  The 
observations completed with no reported problems.

    1.09 Completed STIS/CCD 8796 (POMS Test Proposal: STIS Non-Scripted 
Parallel Proposal Continuation IV)

        The Space Telescope Imaging Spectrograph (CCD) was used  in the 
parallel mode to make some low galactic latitude archive observations.  The 
observations were executed as scheduled, and no anomalies were noted.

    1.10 Completed STIS/CCD 8240 (Wilson Masses and Spins of Black Holes in 
Seyfert Galaxies)

        The Space Telescope Imaging Spectrograph (CCD) was used to observe 
about 20 bright Seyfert 1 galaxies that are now known to have very broad 
{up to 100, 000 km s^-1} Fe KAlpha emission lines near 6.4 keV.  The 
observations completed nominally.

    1.11 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.

    1.12 Completed STIS/CCD 8135 (Spectroscopy of Gravitational Lens 
Candidates from the HST Survey of BL Lac Objects)

        The Space Telescope Imaging Spectrograph (CCD) was used to make 
spectroscopic observations of two new gravitational lens candidate, 
0502+675, discovered in our HST R-band snapshot survey of ~100 BL Lac 
objects.  It contains a double point source with separation of only 0.3 
arcsec.  A candidate for the lensing galaxy has also found.  STIS long-slit 
spectra of each point source will determine whether these candidates are 
lenses and also measure the redshift of the possible lensing galaxy.  The 
proposal completed nominally.
