Daily Status Report as of 005/0000Z

1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

   1.1 Completed Two Sets of STIS/CCD 7948 (CCD Dark and Bias Monitor --
Cont. to Dec. 98)

       The Space Telescope Imaging Spectrograph (CCD) was used to measure
CCD dark current and bias rates for the two supported amplifier settings
{GAIN=1 and GAIN=4} in order to gather data for making superdarks and
superbiases.  The data will be used to track the growth of hot pixels on
the CCD in general and within the various target acquisition apertures
specifically.  The observations were executed as scheduled, and no
anomalies were noted.

   1.2 Completed Four Sets of WF/PC-2 7620 (WF/PC-2 Cycle 7 Standard Darks)

       The WF/PC-2 was used to make a series of Cycle 7 standard dark
calibration images.  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.

   1.3 Completed Eleven Sets of NIC/1/2/3 8093 (DARKs: Warming Up - Part II)

       The Near Infrared Camera (Cameras One, Two and Three) was used to
make a series of dark calibration observations.  The purpose of this
proposal is to monitor the detector dark current during the interval
between the end of science observations and the exhaustion of cryogen and
subsequent warming of the dewar to > 100K.  The observations were executed
as scheduled, and no anomalies were noted.

   1.4 Completed STIS/CCD/MA1 7481 (The Wind-momentum Luminosity
Relationship for M31 and M33 B-supergiants)

       The Space Telescope Imaging Spectrograph (CCD and MA1) was used to
make observations of the B class supergiant star M-31-OB78-1 which is
locate in the M-31 galaxy.  The purpose of these observations is to
acquire STIS low-resolution ultraviolet spectra of early B-supergiants in
galaxies M31 and M33 to determine the terminal velocities of their stellar
winds.  The observations were completed as planned, and no anomalies were
reported.

   1.5 Completed Five Sets of NIC/1/2/3 8083 (FLATs: Warming Up - continuation)

       The Near Infrared Camera (Cameras One, Two and Three) was used to
monitor the flat fields during the interval between the end of science
observations and the exhaustion of cryogen and subsequent warming of the
dewar to > 100K.  The observations were executed as scheduled, and no
anomalies were noted.

   1.6 Completed Three Sets of WF/PC-2 7713 (WF/P-2 Cycle 7 Supplemental
Darks pt3/3)

       The WF/PC-2 was used to make supplemental dark calibration images.
This dark calibration program obtains 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 anomalies were noted.

   1.7 Completed Three Sets of WF/PC-2 7623 (WF/PC-2 Cycle 7 Internal Flats)

       The WF/PC-2 was used to make a set of internal Cycle 7 calibration
flats which are designed to monitor the pixel to pixel flat field response
and the visflat lamp degradation, as well as detect any possible changes
due to contamination.  The calibration observations were completed as
planned, and no problems were reported.

   1.8 Completed WF/PC-2 7377 (Dwarf Elliptical Galaxy Snapshot Survey II)

       The WF/PC-2 was used to make observations of the dwarf elliptical
galaxy FCC246 as part of Snapshot Survey II.  This survey will provide
important information on the globular cluster systems of such galaxies and
the properties of their cores and nuclei.  The observations were completed
as planned, and no anomalies were reported.

   1.9 Completed Three Sets of STIS/MA1 7950 (Cycle 7 MAMA Dark Measurements)

       The Space Telescope Imaging Spectrograph (MA1) was used to make a
dark calibration image.  This is to establish if the detectors are
performing nominally, that no internal movement of the MCP has taken place,
and establish dark level in orbit for a given operating temperature.  These
darks will be used in later image reduction and also trended over
instrument life time as indicators of detector degradation or damage.  The
observations were completed as planned, and no problems were reported.

   1.10 Completed WF/PC-2 6699 (The Globular Cluster System of the Dwarf
Elliptical System Galaxies NGC-185 and NGC 205)

       The WF/PC-2 was used to make observations of the globular cluster
system around the nucleus of dwarf galaxy NGC-205.  The propose is to carry
out a general reconnaissance of the properties of the globular clusters.
The observations were completed as planned, and no anomalies were reported.

   1.11 Completed STIS/CCD 7912 (STIS Parallel Archive Proposal - Nearby
Galaxies - Imaging and Spectroscopy)

       The Space Telescope Imaging Spectrograph (CCD) was used to make
parallel observations of nearby galaxies.  This survey will be useful to
study the star formation histories, chemical evolution, and distances to
these galaxies.  These data will be placed immediately into the Hubble Data
Archive.  The observations were completed as scheduled, and no problems
were reported.

   1.12 Completed Eight Sets of STIS/CCD 8091 (POMS Test Proposal: STIS
Non-Scripted Parallel Proposal Continuation III)

       The Space Telescope Imaging Spectrograph (CCD) was used to make high
galactic latitude, non-scripted, parallel observations.  The observations
were completed as planned, and no anomalies were noted.

   1.13 Completed Three Sets of STIS/CCD 8084 (POMS Test Proposal: STIS
Non-Scripted Parallel Proposal Continuation)

       The Space Telescope Imaging Spectrograph (CCD) was used to make
non-scripted parallel high galactic latitude observations as part of POMS
test proposal.  The observations were executed as scheduled, and no
anomalies were noted.

   1.14 Completed WF/PC-2 6355 (A UV Atlas of Nearby Galaxies)

       The WF/PC-2 was used to make ultraviolet observations of the nearby
galaxy NGC-1507.  The aim of the project is to build a reference
ultraviolet atlas of galaxies whose optical images are well known, with the
highest possible degree of information, covering all the morphological
types and luminosity classes.  The observations were executed as scheduled,
and no anomalies were noted.

   1.15 Completed NIC/2/3 7962 (NICMOS Warm-up Focus Monitoring)

       The Near Infrared Camera (Cameras Two and Three) was used to make
observations of the globular cluster and nebula of NGC-3603 as part of the
NICMOS warm-up focus monitoring.  This proposal is used to determine and
monitor the optimal focus settings for NIC/2 and NIC/3 during the dewar
warm-up period at the end of 1998.  The observations were executed as
scheduled, and no anomalies were noted.

   1.16 Completed WF/PC-2 6669 (Imaging of Two Dwarf Galaxies in Tidal Tails)

       The WF/PC-2 was used to make observations of tidal trails of the two
merging dwarf galaxies in NGC-4038.  These two dwarf galaxies are part of
the M-81 group, and recent models suggest that it is interacting with, but
has not formed from, the H-1 surrounding M81.  The observations were
completed as planned, and no anomalies were reported.

   1.17 Completed Three Sets of NIC/2/3 8082 (NICMOS Pure Parallel Fall 98)

       The Near Infrared Camera (Cameras Two and Three) was used to make
pure parallel observations while another instrument is prime.  The
observations were executed as scheduled, and no anomalies were noted.

   1.18 Completed NIC/2/3 8063 (NICMOS Pure Parallel Sponge - Backup)

       The Near Infrared Camera (Cameras Two and Three) was used to make
observations taken in parallel with the prime science observations.  This
proposal is PRE-the new FOM default.  The observations were executed as
scheduled, and no anomalies were noted.
