Daily Status Report as of 152/0000Z

1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

   1.1 Completed 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 GHRS/1/2 6594 (White Dwarf Companions of Barium and CH =
Peculiar Stars)

       The High Resolution Spectrograph (Sides One and Two) was used to =
attempt to make spectrographic observations of the white dwarf of the =
Barium and CH Peculiar class star HD40808.  This will test the theory =
that abundance anomalies in this star caused by mass transfer from the =
precursor of the white dwarf.  The observations were executed as =
scheduled, and no anomalies were noted.

   1.3 Completed WF/PC-2 5997 (The Cores of Elliptical Galaxies in the =
Coma Cluster)

       The WF/PC-2 was used to make observations of the large elliptical =
galaxies NGC-4957 and Gal-131208 which are located in the Coma Cluster.  =
The purpose is to study the luminosity profiles in their central nuclear =
regions.  The observations were completed as scheduled, and no anomalies =
were noted.

   1.4 Completed WF/PC-2 6888 (Scattered Emissions From the Active =
Nucleus Buried in NGC-4258)

       The WF/PC-2 was used to make observations of the buried active =
nuclear region and its surrounding disk of galaxy NGC-4258 to study its =
scattered ultraviolet emission lines.  The observations were completed as =
planned, and no anomalies were noted.

  1.5 Completed WF/PC-2 6557 (WF/PC-2 Imaging of Intermediate Redshift =
Absorption Selected Galaxies)

       The WF/PC-2 was used to make observations of the galaxy Q1623 =
where a halo appears to be absorbing light from the background =
quasi-stellar object (QSO).  The observations were completed as planned, =
and no problems were reported.

   1.6 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 IR13428+56.  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.

   1.7 Completed WF/PC-2 6533 (Shock Fronts of Protoplanetary Nebulae)

       The WF/PC-2 was used to make narrow and medium band  observations =
of the shock fronts in the protoplanetary nebula system (class PPNe) =
M1-92.  The interaction between the Active Giant Branch AGB object and =
the post-AGB stellar winds is thought to be the dominant factor that =
determines the evolution and shape of the PPNe.  The observations were =
executed as scheduled, and no problems were reported. 

   1.8 Completed FGS 6268 (The Parallax of NGC-6853)

       The FGSs were used to make astrometric observations in order =
measure the parallax to NGC-6853, one of the nearest planetary neabulae.  =
The observations were executed as planned, and no problems were reported.

   1.9 Completed Two Sets of WF/PC-2 6363 (The Environments and Host =
Galaxies of BL-Lac Objects)

       The WF/PC-2 was used to make snapshot survey observations of =
BL-Lac objects PKS2005 and H1426+428 in order to study their environment =
and their host galaxies.  The goal is to investigate systematic trends in =
host galaxy type, unusual morphological features, nearby companion =
galaxies, etc.  The observations were executed as scheduled, and no =
anomalies were noted.

   1.10 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 B21148+38 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.
