Daily Status Report as of 323/0000Z

1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

   1.1 Completed Three Sets of WF/PC-2 6253 (Pure Parallel Archive =
Program)

       The WF/PC-2 was used to execute a pure parallel program taking =
ultraviolet observations running concurrently with prime science =
observations.  The intent is to search for extra-galactic sources with =
flux excesses at 3000 A0 and galactic sources with excesses at 1600 A0.  =
The observations were completed as planned, and no problems were =
reported.

   1.2 Completed Four Sets of FOS/BL 6407 (Post Asymptotic Giant Branch =
Evolution in the Magellanic Clouds)

       The Faint Object Spectrograph (Blue Side) was used to make =
ultraviolet spectrographic observations of planetary nebulae LMC-SMP15, =
LMC-SMP41, LMC-SMP54 and LMC-SMP01 which are located in the Large =
Magellanic Cloud.  These data should give the spatial structure, size, =
ionized masses, and dynamic ages of these objects.  At 321/052249Z, =
during the second iteration of this proposal, there was an FOS target =
acquisition failure.  HSTAR 5799 was written.  The observations were =
executed as planned, and no problems were reported. 

   1.3 Completed FOS/BL 6683 (Eclipsing Binaries in the Magellanic Clouds =
- Fundamental Properties A)

       The Faint Object Spectrograph (Blue Side) was used to make =
spectrographic observations of O/B Class, eclipsing binary system star =
LMC HV2274 located in the Large Magellanic Cloud.  From these data and =
the latest Kurucz model atmospheres, accurate temperatures will be =
derived.  The observations were executed as scheduled, and no anomalies =
were noted. 

   1.4 Completed FOS/RD 6654 (Ultraviolet Spectroscopy of Hot DB White =
Dwarfs)

       The Faint Object Spectrograph (Red Side) was used to make =
observations of the hot, helium-atmosphere, DB White Dwarf class, star =
WD0112+104.  The ultraviolet spectra will be used to determine the =
effective temperatures of this star, which shows discrepancies when =
calculated from the optical spectra due to traces of photospheric =
hydrogen which is not visible at optical wavelengths.  The observations =
were executed as scheduled, and no anomalies were noted. 

   1.5 Completed Two Sets of WF/PC-2 7211 (WF/PC-2 Pre-SM97 UV Baseline =
Observation.)

       The WF/PC-2 was used to make far-ultraviolet observations of CVZ =
Class targets GRW+70D582 and WD0310-688 as part of a pre-observation =
baseline of SM97 (WF/PC-2 SMOV Calibration).  The observations were =
completed as scheduled, and no anomalies were noted.

   1.6 Completed FOS/BL 6546 (Dissecting the wind and Disk of the =
Nova-like Variable V347 Puppus)

       The Faint Object Spectrograph (Blue Side) was used to make =
observations of the nova-like, variable star V347 Puppus in order to =
study its disk and to dissect its winds.  The ultraviolet resonance =
spectral lines indicate that this type of cataclysmic variable suffers a =
high mass loss rate in the form of high velocity winds.  The observations =
were completed as scheduled, and no problems were reported. 

   1.7 Completed Two Sets of WF/PC-2 7203 (Cosmology with the Medium Deep =
Survey - Short Orbit Cases)

       The WF/PC-2 was used to take short (about 20 minute) exposures, to =
be taken in parallel with the prime science observations, using the I =
filter.  These exposures are part of the medium-deep survey, which =
emphasizes exposures that will be useful in obtaining cosmological =
parameters.  The observations were completed as planned, and no problems =
were reported.

   1.8 Completed WF/PC-2 6906 (WF/PC-2 Cycle 6 Calibration: Internal =
Monitor-Visual Flats)

       The WF/PC-2 was used to make internal calibration visual flat =
images as part of the Cycle 6 internal monitoring of the instrument's =
operations.  This proposal defines the standard series of internal flat =
fields, which will be executed twice per month.  The observations were =
completed as planned, and no anomalies were reported.

   1.9 Completed GHRS/2 6010 (Lyman Alpha Observations of High Radial =
Velocity Stars)

       The High Resolution Spectrograph (Side Two) was used to make =
ultraviolet spectrographic observations of the star HD6755 which is known =
to have a high radial velocity in order to study its Lyman-Alpha line =
complex.  A wavelength calibration image was also taken.  The =
observations were executed as scheduled, and no anomalies were noted. 

   1.10 Completed WF/PC-2 6002 (Spectroscopy of the Rapidly Rotating =
Nuclear Disk in the Virgo S0 NGC-4526)
'
       The WF/PC-2 was used to make spectrographic observations of the =
rapidly rotating nuclear disk in S0 class galaxy NGC-4526 which is =
located in the Virgo Cluster.  The nucleus of this galaxy was imaged in =
Cycle 4, and new images with different filters were used to make color =
corrections and allow the subtraction of the stellar continuum.  The =
observations were completed as planned, and no problems were reported.

   1.11 Completed Three Sets of WF/PC-2 6609 (The WF/PC-2 B-Band Parallel =
Survey: A Systematic and Synoptic Study )
'
       The WF/PC-2 was used to make B-Band survey observations in =
parallel with the prime science observations.  A total of 216 exposures =
will be taken over a period of time to make a statistical study of the for=
mation and evolution of the galaxies.  The observations were executed as =
scheduled, and no anomalies were noted. 

   1.12 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 QDOTULIR09.  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.

   1.13 Completed FOS/RD 6548 (The Cool Interstellar Medium in Hot =
Cluster of Galaxies)

       The Faint Object Spectrograph (Red Side) was used to make =
ultraviolet resonance absorption line observations of quasar QSO0020+28 =
in order to study the cool interstellar medium within a cluster of =
galaxies which lie within the line of sight to the quasar.  The QSO is =
being used a probe of the galactic cluster.  The observations were =
executed as scheduled, and no anomalies were noted. 

   1.14 Completed WF/PC-2 7202 (The WF/PC-2 B Band Parallel Survey: A =
Systematic and Synoptic Study of Galaxy Formation and Evolution - Short =
Orbit Case)

       The WF/PC-2 was used to make observations as part of a B-Band =
Survey to make synoptic study of galaxy formation and evolution.  These =
observations were taken in parallel with the prime science observations.  =
They were completed as planned, and no anomalies were reported.

   1.15 Completed GHRS/1 6463 (The Origin of the Peculiar Hybrid PG 1159 =
Stars)

       The High Resolution Spectrograph (Side One) was used to make =
observations of NGC-70 and an Abell Cluster in order to study the origin =
of the peculiar hybrid STAR-2324 Class of stars.   The data will be used =
to obtain an improved value of the effective temperature, and the spectra =
will be compared to the latest model atmospheres to learn more about the =
evolution of  PG 1159 stars.   The observations were completed as =
scheduled, and no problems were noted. 

   1.16 Completed FOS/RD 6577 (An Expanded Survey for Study of the =
Lyman-Alpha Line and QSO Mg II Absorption)

       The Faint Object Spectrograph (Red Side) was used to make =
observations of the QSO PKS1354+25 in order to make a survey of the =
Lyman-Alpha line and the 68 Mg II absorption line system.  The =
observations were completed as scheduled, and no problems were reported. 

   1.17 Completed FOS/BL 6799 (The BAL Region Covering Factor in a Sample =
of IRAS-Selected QSOs)

       The Faint Object Spectrograph (Blue Side) was used to make =
spectrographic observations of QSO IR20450-295 in order to determine the =
criteria by which the presence of BALs in the spectra may be predicted.  =
The observations were completed as planned, and no problems were =
reported.
