Daily Status Report as of 129/0000Z

1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

   1.1 Completed GHRS/2 6169 (HRS Eschelle Wavelength Monitor)

       The High Resolution Spectrograph (Side 2) was used to calibrate =
carrousel function, Y-deflection, resolving power, sensitivity, and =
scattered light for both eschelle-A and eschelle-B.  All exposures are =
internals.  The observations were completed as planned, and no problems =
were reported.

   1.2 Completed WF/PC-2 6184 (WF/PC-2 Cycle 5 Photometric Calibration =
Monitor UV/OPT STD)

       The WF/PC-2 was used to make ultraviolet and optical observations =
of standard star GRW+70D582 in order to monitor the photometric =
calibrations of the camera and to check for decontamination.  The =
observations were executed as scheduled, and no anomalies were noted.

   1.3 Completed Four Sets of WF/PC-2 6187 (WF/PC-2 Cycle 5 Calibration: =
Earth Flat)

       The WF/PC-2 was used to make Earth streak flat calibration images. =
 These streak flats will be used to produce flat fields, to map the OTA =
illumination pattern and, in combination with other data, to produce new =
superflats.  The observations were completed as planned, and no problems =
were reported.

   1.4 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-4876 and Gal-125942 which are located in the Coma Cluster.  =
The purpose is to study the luminosity profiles in the central nuclear =
region.  Approximately half-way through this one-hour proposal, a primary =
acquisition failed to fine lock back-up on one FGS only.  HSTAR 5601 was =
written.  No further anomalies were noted.

   1.5 Completed FOS/BL 6750 (Spectropolarimetry of Ultraviolet Continuum =
and Line Emissions in Binary Systems)

       The Faint Object Spectrograph (Blue Side) was used to make =
ultraviolet continuum and emission line spectropolaragraphic observations =
of the eclipsing binary star system TT-Hya.  The observations were taken =
during the primary eclipse.  The observations were executed as scheduled =
and no anomalies were noted.

   1.6 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.

   1.7 Completed WF/PC-2 6431 (Determination of the Extragalactric =
Distance Scale)

        The WF/PC-2 was used to make observations of the galaxy NGC-4548 =
to be used in measuring the periods of Cepheid variable stars within this =
galaxy.  This will allow for a more accurate estimate of the distances to =
these galaxies through the period-luminosity relation for the Cepheid star=
s.  The observations were executed as scheduled, and no anomalies were =
noted.

   1.8 Completed FGS 6274 (Linking the HIPPARCOS to the Extragalactic =
Referance Frame)

       The FGS#3 was used to make astrometeric observations of =
extra-galactic objects NEWEGOC-50, 420-REF, NEWHIP-50 and several other =
reference stars in order to help link the HIPPARCOS satellite reference =
frame to that of the HST.  The observations were completed as planned, =
and no anomalies were reported.

   1.9 Completed FOC/96 5960 (Identifying the Polarization Seyfert 1 =
Mirror in Markarian 463)

       The Faint Object Camera (F/96) was used to make polarized light =
observations of Markarian galaxy MARK463 which is a Class 2 Seyfert =
galaxy that displays Seyfert Class 1 spectrum in polarized light.  The =
observations were completed as scheduled, and no problems were reported.

   1.10 Completed Four Sets of WF/PC-2 5964 (Detecting Emission Lines at =
Half the Hubble Time)

       The WF/PC-2 was used as part of a parallel program to make observat=
ions which are used to search for emission lines in distant clusters of =
galaxies.  The objective is to study star formation at Z=3D 0.75.  The =
observations were completed as planned and no problems were reported.
