PERIOD COVERED:  0800 EST 01/15/93 - 0800 EST 01/19/93

Daily Status Report as of 019/1200Z.

1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

   1.1 Completed Three Sets of WFC 1297 (GTO High Latitude Parallel Program)

       The Wide Field Camera was used to take a series of high latitude
       images which were taken in parallel with the prime science
       observations. All of the observations were executed as scheduled,
       and the observations were reported to to be full of stars. 

   1.2 Uplinked Updated Ephemeris Tables, Per MOSES 2871

   1.3 Completed GHRS/2 3372 (Point Spread Function Determination)

       The High resolution Spectrograph was used to make a large series of
       observations of the point spread function (PSF) as it relates to the
       large science aperture (LSA). Observations were made using the
       standard stellar target HD141556. All the observations executed with
       no apparent problems in the telemetry. 

   1.4 Completed PC 4140 (Rapid Internal Monitor - Part 2)

       The Planetary Camera was used to take internal flat observations to
       check for new forms of contamination and the return of quantum
       efficiency hysteresis (QEH). The observations were  monitored in the
       OSS, and no problems were reported. 

   1.5 Completed FOS/BL 4057 (Spectrography of QSOs)

       The Faint Object Spectrograph (Blue Side) was used to make three
       ultraviolet spectral observations below 3000 A0 of quasar I-ZW1. The
       execution of the observations were monitored in the OSS, and all of
       the observations were reported to look okay. 

   1.6 Completed FOS/BL 4110 (The Physics of Massive O-Type Stars)

       The Faint Object Spectrograph was used to make set of nine
       ultraviolet (from 1150 A0 to 2300 A0) spectral observations of OB
       class star SK67D166 which is located in the Large Magellanic Cloud.
       The first six observations were received and displayed. They all
       looked good. The next onboard binary target acquisition succeeded,
       but the following peak up had the maximum count in the last group,
       which indicates that the centering of the target was not well known.
       The last observations were reported to look good. 

   1.7 Completed WFC-PC 4109 (Rapid Internal Monitor)

       Both the Planetary Camera and the Wide Field Camera using filter
       F555W were used to take two internal flat observations to check for
       new forms of contamination (i.e., Daisies and measles). Both images
       were received and displayed in the OSS. They both were reported to
       look normal. 

   1.8 Completed  Two Sets of PC 4714 (Rapid Internal Monitor)

       The Planetary Camera was used to make two internal flat
       observations. The images will be used for the restoration of Earth
       flats, which have been altered due to changes in the quantum
       efficiency which occurred after WFPC decontamination operations.
       Both observations were executed without apparent problems, and were
       reported to look normal. 

   1.9 Completed FOS/RD/BL 3647 (Star forming Histories of Elliptical 
       Galaxies)

       The Faint Object Spectrograph was used to make two spectral
       observations (both the blue and red sides) of elliptical galaxy
       NGC-1399. This is to study the constraints on the metallicity and
       age distribution of the hot star in this galaxy. Part of the first
       observation was not received due to a TDRSS hand-over which
       interrupted the data transmission. The other observations looked
       noisy, but had enough signal after the observations had been
       co-added. 

   1.10 Completed WFC 4105 (HST Medium Deep Survey High Latitude) 

       The Wide Field Camera was used to make two observations to be used
       for a medium-deep sky survey. These observations were take in
       parallel with the primary science observations. There were no
       apparent problems. 

   1.11 Completed Two Sets of WFC 3917 (HST Medium Deep Survey - Part 1)

       The Wide Field Camera was used to make two observations which were
       taken in parallel with the prime science observations. The
       observations were monitored in the OSS, and no problems were
       reported. 

   1.12 Completed FOC/96 3880 (Absorption Lines in Planetary Nebulae)

       Observations were made of the central star in protoplanetary nebula
       BD+30D3639. Star light from the central star is used to probe the
       neutral material surrounding this star. Two observations were
       executed in fine lock. A recentering event occurred during the first
       observation and had no effect on the observation. Both images were
       reported to have stellar type object within the field of view. 

   1.13 Completed WFC 1306 (GTO Low Latitude Parallel Program)

       The Wide Field Camera was used to make two low latitude observations
       taken in parallel with the prime science observations. These
       observations are looking for low mass stars, close visual binaries,
       and shells surrounding late type stars. Both observations were
       executed in fine lock. There was no loss of lock, but a recentering
       event did occur. Both images were reported to be full of stars. 

   1.14 Completed FOS 4000 (Quasar Absorption Line Survey)

       The Faint Object Spectrograph was used to make series of
       observations for a spectral line survey of Quasar PKS2340-03. There 
       were binary and peakup acquisitions followed by a RAPID-mode
       spectra using the FOS red side detectors. The observations were
       executed as planned, and they encountered no apparent problems. 

   1.15 Completed FOC 3801 (Search for QSOs Suitable for Subsequent 
        Observations)

       The Faint Object Camera was used to make ultraviolet flux
       observations of quasar 0118+0119 to search for quasars to be used in
       further detailed studies. The observations were not monitored in 
       real time. After the science tape recorder playback, the two images
       showed no visible objects. Since this was one of the possible
       expected outcomes of the observations, the observations were not
       reported as being bad. 

   1.16 Completed FOC 3815 (UV Observations of Hubble Sandage Variables)

       The Faint Object Camera was used to make two images of
       Hubble-Sandage class stars which are located in galaxy M-31 (aka,
       the Andromeda Galaxy). These are very luminous, eruptively unstable
       stars of the same type as Eta Carina. The science tape recorder
       playback of the image showed multiple targets in both images 


   1.17 Completed PC 4764 (Investigation of Dynamics of Binary Asteroids)

       The Planetary Camera was used to take a series of images of
       suspected binary asteroid 18 Melpome. Its binary nature has been
       suspected because of its unusual light curve. The baseline guide
       star acquisition was made in course track. The profiled slew and the
       image observations of the asteroid were successful. 

   1.18 Completed Three Sets of FOS/RD 3744 (Spectrophotometry of Phobos and
        Deimos) 

       The Faint Object Spectrograph (Red Side) was used in the prism mode
       with the one arcsecond aperture to make observations of Mars' two
       moons Phobos and Deimos. The initial guide star acquisition failed,
       and as preplanned the FOS was safed by stored command load
       instructions at 018/1054Z. The FOS was recovered by real-time
       commanding at 018/1815Z. The recovery was successful. The following
       baseline acquisition for observations of the moon Phobos were
       successful. There was some trouble holding the image in the
       observation aperture window. A corrective SIP maneuver was uplinked.
       The onboard target acquisition succeeded and executed with no
       problems. 

       During a subsequent observation, the baseline guide star acquisition
       for observations of Deimos failed. The FGS #2 had a stop flag and
       search radius limit exceeded flag set. A corrective SIP maneuver was
       uplinked, however, following observations did not show the moon
       Deimos in the field of view. 

   1.19 Completed PC 3603 (Snapshots of Protoplanetary Nebulae)

       The Planetary Camera was used to make a single observation of the
       protoplanetary nebula around this star PK211-03D1. The observations
       was received and displayed. It was reported to look good. 

   1.20 Completed FOS/RD/BL 4694 (Stellar Content of Galaxies and Globular 
        Clusters)

       An attempt was made to make observations of four different globular
       clusters in the Galaxy M-31 (aka, Andromeda Galaxy). However, The
       planned six observations did not occur because the FOS was safed. An
       attempt on the last observation was bad because the onboard target
       acquisition did not occur. 

   1.21 Completed PC 4106 (HST Medium Deep Survey: Low Latitude)

       The Planetary Camera was used to make a series of observations taken
       in parallel with the prime science observations. These are to
       provide for serendipitous discoveries and to supply data for a basic
       sky survey. The observations were executed as scheduled, and no
       problems were reported. 

   1.22 Completed PC 4712 (Measles Monitor)

       The Planetary Camera was used with filter F517N to obtain Earth flat
       calibration images to monitor the appearance and number of measle
       contamination points. The observations were monitored in the OSS,
       and no problems were reported. 

   1.23 Completed PC 3230 (PSF and Focus Monitoring 2)

       The Planetary Camera was used to observe the 8th magnitude standard
       star SAO55685 to monitor the point spread function and focus changes
       caused by desorption and other changes within the WFPC system. The
       observations were executed in course track. All the data was
       received and displayed. In one of the images the star appeared on
       the Baum spot, and the observation was reported to be bad. 

   1.24 Completed HSP/UV2 3798 (Search for Radial Pulsations in White 
        Dwarfs)

       An attempt was made to look for radial pulsations in the hot white
       dwarf star G130-5 using the High Speed Photometer. The baseline
       guide star acquisition failed to obtain fine lock. The stop flag and
       the search limit exceeded flag were set for FGS #2. The observations
       was monitored in real-time, and there were almost no counts in the
       FGS #2 PMTs. 

   1.25 Completed FOS/BL 3816 (White Dwarf Stars)

       The Faint Object Spectrograph was used to obtain ultraviolet
       spectral observations of white dwarf star G29-38. The observations
       were monitored in the OSS, and no problems were reported. 

   1.26 Initiated HSP/UV2 1095 (Variability of High Luminosity Stars)

       Observations have been initiated using the High Speed Photometer to
       monitor one of the most massive and luminous known stars HD15570.
       The observations are currently under way, and no problems have been
       reported.

   2.3 Significant HSTARs: 

      HSTAR 3810  The Faint Object Spectrograph was automatically placed in
      Safe Mode by a stored command load at 018/1054. This was during an
      observations of Mars' two moons. The baseline guide star acquisition
      for observation 3744 failed, and as planned the FOS was placed in
      Safe Mode to prevent an over-light condition in the FOS. The FOS was
      recovered by real-time commanding at 018/1815Z and subsequent
      observations using the FOS were successful. (See Section 1.18) .
