Daily Status Report as of 115/0000Z

1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

   1.1 Completed Two Sets of FGS 6147 (Extragalactic Astronomy and
Astrophysics Final: Cycle 4 Observations)

       The FGSs were used to make observations of targets 0637-752IN,
1120-REF, 1121-REF, INCA221-39, NEWEGOD-57, 520-REF, 521-REF, 522-REF and
NEWHIP-57. The objective of this long-term program is to determine the
rotation of the HIPPARCOS reference relative to the extragalactic frame. The
observations were executed as scheduled, and no anomalies were noted.

   1.2 Completed WF/PC-2 5092 (GTO Low Latitude Parallel Program: Cycle 4) 

       The WF/PC-2 was used to make observations taken in parallel with the
prime science observations. This is part of a survey to take pictures of a
large number of fields within 30 degrees of the galactic plane. The
observations were completed as planned, and no problems were reported.

   1.3 Completed Three Sets of WF/PC-2 5562 (WF/PC-2 Cycle 4 Calibration:
Internal Monitor 3: Darks)

       The WF/PC-2 was used to obtain several 30-minute long, dark exposures
to provide ongoing calibration of the CCD dark current and to monitor and
characterize the evolution of hot pixels. The observations were executed as
scheduled, and no anomalies were noted. 

   1.4 Completed WF/PC-2 5479 (Subarcsecond Structure in Nearby AGNs)

       The WF/PC-2 was used to make snapshot observations of the nearby
active galactic nuclei of TOL1220+05 to study the interactions between the
central  engine, the stars, and the interstellar matter in the AGN. The
observations were executed as scheduled, and no anomalies were noted. 

   1.5 Completed WF/PC-2 5397 (Determination of the Extragalactic Distance
Scale: Cycle 4 High)

       The WF/PC-2 was used to make images of galaxy NGC-4414 to be used in
measuring the periods of Cepheid variable stars within this galaxy. The
observations were completed as planned, and no anomalies were noted.

   1.6 Completed WF/PC-2 6142 (WF/PC-2 Cycle 4 Calibration: Earth Flats,
Smaller Set Part II)

       The WF/PC-2 was used to make Earth Flat calibration images for the
ultraviolet and narrow-band filters to correct for the telescope's
illumination pattern. The observations were executed as scheduled, and no
anomalies were noted.

   1.7 Completed FOS/BL 6146 (FOS Location of Spectra and Aperture - Part 2)

     The Faint Object Spectrograph (Blue Side) was used to conduct a test to
determine the repeatability of positioning the filter-grating wheel. All
observations were internal. A wave length calibration image was also taken.
All observations were executed as scheduled, and no anomalies were noted.

   1.8 Completed Three Sets of WF/PC-2 5091 (GTO High Latitude Parallel
Program: Cycle 4)

       The WF/PC-2 was used in parallel with the prime science observations
to make high galactic latitude observations greater than +/-30 degrees. The
observations were executed as scheduled, and no problems were reported.

   1.9 Completed WF/PC-2 5629 (WF/PC-2 Cycle 4 Photometric Calibration
Monitor 1C: 4-Chip STD in F170W)

       The WF/PC-2 was used to make photometric calibration observations of
the ultraviolet standard star GRW+70D582. The observations were executed as
scheduled, and no anomalies were noted. 

   1.10 Completed WF/PC-2 5981 (Calibration of Nearby Type IA supernova as
Standard Candles: NGC-4639)

       The WF/PC-2 was used to make observations of Cepheid variable stars in
Galaxy NGC-4639 (which has produced a Type IA Supernova) to calibrate the
nova's absolute brightness so that it can be used as a standard candle for
distance measurements.
The observations were executed as scheduled, and on anomalies were noted.

   1.11 Completed GHRS/2 5728 (Absorption Cloud Physics in Seyfert Galaxy
Nuclei: Cycle 2)

       The High Resolution Spectrograph (Side Two) was used to make
spectrographic observations of a C IV region in Seyfert  galaxy NGC-3516 to
study the structure and velocity in the line of sight. Variability of the
spectra on a time scale of months has been reported in this object. The
observations were completed as scheduled, and no problems were reported.
