PERIOD COVERED:  0800 EST
Daily Status Report as of 109/1200Z.

1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

   1.1 Uplinked Updated Ephemeris Tables, Per MOSES 2871

   1.2 Completed PC 4712 (WF/PC Cycle 2 Calibration: Measles Monitor)

       The Planetary Camera was used to make Earth calibration flat images
       with filter F517N, both with and without filter F122M. These images
       are to be used to monitor the appearance and number of measles
       (i.e., contamination marks). The observations were executed as
       scheduled, and no problems were reported. 

   1.3 Completed PC 4109 (WF/PC Cycle 2 Calibration: Rapid Internal Monitor)

       The Planetary Camera was used to make internal flat calibration
       using filter F555W images to check for new forms of contamination
       (i.e., daisies and measles), and the possible return of quantum
       efficiency hysteresis. The observations were executed as scheduled,
       and no problems were reported. 

   1.4 Completed PC 3458 (Stellar Population Gradients in Post Core Collapse 
       Globular Clusters)

       A total of seven images were made using the Planetary Camera of
       globular cluster NGC-6284 of its central cusp region to analyze its
       population and color gradients. Recentering events were noted during
       several of the observations. All seven of the observations were
       examined, and were reported to look satisfactory. 

   1.5 Completed GHRS/2 3608 (The 12C to 13C Isotropic Ratio in Planetary 
       Nebulae)

       The High Resolution Spectrograph (Echelle Mode) was used to make
       ultraviolet spectral observations of planetary nebula NGC-3918. A
       spiral search target acquisition was used with the return to
       brightest option. The target acquisition was successful, with both
       the science observation and the calibration spectrum reported
       looking good. 

   1.6 Completed PC 4063 (Globular Cluster core Structures and Dynamics 
        (FOS 36) Augmentation)

       The Planetary Camera was used to make ultraviolet images of the
       central core region of globular cluster M-80 (aka, NGC-6681) to
       located objects for future FOS observations. A total of four
       observations were monitored in the OSS, and no problems were seen in
       the telemetry. 

   1.7 Completed GHRS/2 4094 (Spectroscopy of Milky Way Halo Gas - 
       Augmentation Cycle 2)

       The High Resolution Spectrograph was used to make two spectral
       observations of the star E1821+643 which is located in the halo
       region of the Milky Way Galaxy. Both observations were executed in
       fine lock. There was at least one recentering event during the
       second observation. They both were reported to look fine. 

   1.8 Completed FGS 4820 (Spring Heptathlon)

       A series of eight calibration and alignment observations were made
       with the SIs (i.e.,FOS,FOC,HSP,and GHRS) along with the WFC and FGSs
       to determine the focal plane and FGS stability, and the relative
       positions of the SIs. Observations were made using stars in the
       standard calibration cluster. All of the observations were examined
       in the OSS. All onboard target acquisitions were successful. One of
       the observations was partially obscured by a bad diode, and all the
       other observations were reported to look okay. 

   1.9 Completed Two Sets of FGS 4765 (Overlapping Plate Field Distortion
       Calibration /AST-SV-02)) 

       The Fine Guidance Sensor #3 was used to make optical field angle
       distortion (OFAD) observations of stars in the open cluster M-35 in
       Gemini. All of the astrometry observations were monitored, and no
       problems were seen. 

   1.10 Completed GHRS/2 3472 (The Properties of Single Interstellar Clouds 
        Cycle 2)

        The High Resolution Spectrograph (Echelle Mode) was used to make a
        large series of observations of an individual interstellar cloud by
        observing broad lined, early type star HD044743. The observations
        were executed in fine lock. The first series was executed without
        problems, and no anomalies were noted. The second set of
        observations received a status buffer error message, which
        indicated that the carrousel did not reset correctly. Several
        science observations were reported to be missing. Subsequent
        observations were successful. The spectra was reported to look
        excellent. 

   1.11 Completed FOC 4800 (The Stellar Content of Wolf-Rayet Galaxies (FOC
        Images)) 

        The Faint Object Camera was used to make one ultraviolet
        observation of the Wolf-Rayet galaxy MARK33. This galaxy is known
        to be a star bursting galaxy with broad He II emission lines from
        stellar sources. The observations was reported to be an excellent
        exposure. 

   1.12 Completed HSP/UV1 4209 (HSP Detector Sensitivity Test)

        The High Speed Photometer (IDT detectors) were used to make four
        calibrations images of the Ultraviolet standard star BD+75D325 to
        help determine the units long term sensitivity. All four of the
        observations were received and displayed. After the first onboard
        target acquisition, the target was perfectly centered in all the
        images. 

   1.13 Completed WFC 3605 (Extreme Stellar Winds and Post-Main-Sequence 
        Evolution)

        The wide Field Camera was used to make observations of star BE294
        which is located in the Large Magellanic Cloud. These images will
        be used to determine whether this star is suitable for future
        observations with the FOS. The observations were executed as
        scheduled, and no problems were reported. 

   1.14 Complete PC 3603 (Snapshot of Protoplanetary Nebulae)

        The Planetary Camera was used to make observations of the
        protoplanetary system PK051+09D1 to study its current morphology.
        The OSS monitored the observations and assessed the quality of the
        data. No problems were reported. 

   1.15 Completed FOS/BL 4054 (Probing the Nuclear Regions of the Seyfert 
        Galaxy NGC-5548)

        The Faint Object Spectrograph was used to make observations of
        early type galaxy NGC-5548 to study the time variability of its
        continuum fluxes, and emission lines in Helium II and Carbon IV.
        The OSS monitored the observations, and no problems were reported.
