Daily Status Report as of 340/0000Z

1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

   1.1 Completed Two 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 Three Sets of WF/PC-2 6188 (WF/PC-2 Cycle 5 Calibration: =
Dark)

       The WF/PC-2 was used to make internal dark calibration images.  =
The observations were completed as scheduled, and no problems were =
reported.

   1.3 Completed S/C/GHRS/1 6260 (Linear Extent and Ion Cond. in =
Lyman-Alpha Cloud: Cycle 5 Observations)

       The High Resolution Spectrograph (Side One) was used to make =
spectrographic observations between 1215 A0 and 1500 A0 of the QSO =
Q0107-025A in order to study the linear extent and ion Lyman-Alpha cloud. =
 The binary QSO system will be searched for any absorption systems which =
may not be in common with the two objects, thus setting the limits on the =
linear size of its clouds.  A wavelength calibration image was also =
taken.  The observations were completed as planned and no anomalies were =
reported. 

   1.4 Completed FOS/RD 6014 (Spectroscopic Observations of Close Binary =
T-Tauri Stars)

       The Faint Object Spectrograph (Red Side) was used to make =
observations of the variable, close binary, T-Tauri class star V955-Tau.  =
Each component of the binary system is resolvable by the HST.  The =
observations were completed as planned, and no problems were reported.

   1.5 Completed Two Sets of WF/PC-2 6909 (WF/PC-2 Cycle 6 Calibration: =
Earth Flats)

       The WF/PC-2 was used to make observations of the bright Earth to =
obtain streak flats which are used to construct high quality flat fields =
for the WF/PC-2 filter set.  The observations were executed as scheduled, =
and no anomalies were noted.

   1.6 Completed WF/PC-2 6905 (WF/PC-2 Cycle 6 Calibration: Internal =
Monitor)

       The WF/PC-2 was used to make several internal calibrations =
observations including biases and internal flats as part of a Cycle 6 =
calibrations procedure.  A variety of internal exposures are run weekly =
to verify and monitor the health of the camera.  The observations were =
executed as scheduled, and no anomalies were noted.

   1.7 Completed GHRS/1 6707 (M-33: An Archetypal QSO Absorption Line =
Galaxy)

       The High Resolution Spectrograph (Side One) was used to make =
observations of the C IV, Si IV, and Si II spectrographic absorption =
lines QSO Q0121+3154 whose light passes through the galaxy  M-33.  This =
allows for one to probe into the interstellar medium in outer disk and =
halo of galaxy M-33.  Approximately halfway through this two-and-a =
half-hour proposal, a GHRS coarse X-null balance failure occurred during =
a period of relatively unstable pointing, making the target appear to =
move between succewssive frames of data.  After setting the X-correction =
to zero, the observation continued.  These event are described in HSTAR =
5825.  The observations completed as planned, and no further problems =
were noted. 

   1.8 Completed FOS/RD 6204 (FOS Cycle 5 Internal/External Offset)

       The Faint Object Spectrograph (Red Side) was used to make =
spectrographic calibration images of the star HD207757 in order to =
measure the spectrograph's internal and external offsets.  The internal =
lamp was intermingled with the external observations.  The observations =
were completed as planned, and no problems were reported.
