Daily Status Report as of 337/0000Z

1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

   1.1 Completed Six Sets of 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 galaxies IR20100-41, IR11095-02, QDOTULIR06, =
QDOTULIR20, CL-ILIR220 and QDORULIR07.  These data will be searched for =
multiple cores, which imply a merger has occurred, and for starburst =
regions.  As reported in the November 27 report and in HSTAR 5811, in the =
first iteration of this proposal there were quide star acquisition and re-=
acquisition failures when FGS #1 failed to acquire stars.  Otherwise, the =
remaining iterations were executed as scheduled, and no further anomalies =
were noted.

   1.2 Completed Two Sets of WF/PC-2 6348 (Blue Continuum Snapshots of =
3CR Radio Galaxies)

       The WF/PC-2 was used to make some snapshot images of the blue =
continuum in radio galaxies 3C138.0 and 3C445.0.  Combined with existing =
data, these exposures will provide high spatial resolution information on =
the color distribution within galaxies, redding due to dust, spacial =
indices of the optical synchrotron jets, and colors of the active nuclei =
and tidal jets.  The observations were executed as scheduled, and no =
anomalies were noted.

   1.3 Completed FOS/BL 6026 (Structure and Evolution of the Globular =
Cluster Low Mass X-Ray Binary )

       The Faint Object Spectrograph (Blue Side) was used to make =
ultraviolet spectrographic observations of optical counter-part, low =
mass, x-ray, binary star AC-211 in Globular Cluster NGC-7078 (aka M-15).  =
This is to study the structure and evolution of these stars.  The guide =
star acquisiton near the beginning of this 14-hour proposal failed when =
FGS #3 failed to acquire guide stars.  This was initially reported in =
HSTAR 5810 and in the November 27th report.  There were no further =
anomalies noted.

   1.4 Completed WF/PC-2 6802 (Cosmology With the Medium Deep Survey)

       The WF/PC-2 was used to make observations taken in parallel with =

iteration of this proposal, there was an FOS target acquisition failure =
(332/1545Z, 333/0758Z, and 335/0003Z) about one-half hour into the =
approximate 3-hour, 40-minute proposal.  HSTARs 5813, 5814, and 5815 were =
written.  Otherwise, the observations completed as scheduled, and any =
effects on science were not reported. 

   1.6 Completed Ten 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 observati=

excesses at 3000 A0 and galactic sources with excesses at 1600 A0.  The =
observations were completed as planned, and no problems were reported.

will be derived.  The observations were executed as scheduled, and no =
anomalies were noted. 

   1.16 Completed WF/PC-2 6353 (A Snapshot Emission Line Imaging Survey =
of Very Low Excitation Planetary Nebulas)

spectropolarimetry observations of the Seyfert (class two) galaxy MARK273 =
in order to study its geometry and the generalizablity of its reflected =
light model.  The goal is to determine if the polarization components of =
all Seyfert class two galaxies have Seyfert class one characteristics.  =
The observations were completed as scheduled, and no problems were =
reported. 

   1.19 Completed GHRS/2 6456 (The Photospheric Iron Abundance of the UV =
Bright Stars in a Globular Cluster)

       The High Resolution spectrograph (Side Two) wad used to make =
ultraviolet spectrographic observations of five ultraviolet bright stars =
located in the globular cluster NGC-5139 in order to study the stars' =
iron abundances and the prediction given by stellar evolution theory.  =

completed as planned, and no problems were reported.

   1.20 Completed Two Sets of WF/PC-2 6361 (High Resolution Imaging of =
X-Ray Selected AGNs)

       The WF/PC-2 was used to make high resolution  observations of the =
known low red shifted x-ray active galactic nuclius (AGN) MS0225.5+3.  =

luminous, E3 Class, elliptical galaxy IC1459 in order to study its the =
possible black hole in its dynamically decoupled cores.  The observations =
will be used to determine the morphology of the ionized gas.  The loss of =
lock mentioned in 2.1 and reported in HSTAR 5816, resulted in an FOS =
status buffer message indicating that the peakup RTCS had timed out while =
waiting for the spacecraft to become stable.  Otherwise, the observations =
were executed as scheduled, and no further problems were noted.

Beta-Pictoris)

       The Faint Object Spectrograph (Blue Side) was used to make =
ultraviolet spectrographic observations of the disk around the star =
SS2-213 looking for emission lines arising in the inner disk.  The =
objective is to ascertain the composition of the inner disk.  As reported =
in HSTAR 5817, at 335/233518Z during the first of two peakups, an FOS =
status buffer message occurred indicating that the FOS YSPEED check had =
failed.  Later, at 335/233818Z, another status buffer message indicated =
that the subsequent peakup had been successful.  Otherwise, the =
observations completed as planned, and no further problems were reported. =
