1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

   1.1 Completed Three Sets of WF/PC-2 5476 (Continuum Snapshots of 3CR
       Radio Galaxies)

       The WF/PC-2 was used to make snapshot images of radio galaxies
       3C79.0, 3C154.0, 3C191.0, 3C98.0, and 3C198.0 as part of a continuum
       survey and to study the galaxies' morphology. Twelve images were
       received and displayed. Except for a few recentering events, the
       observations were reported to be okay. Two images were reported to
       show the target at the edge of the pyramid, and straddling two
       chips.

   1.2 Completed Two Sets of WF/PC-2 5560 (WF/PC-2 Cycle 4 Calibration:
       Internal Monitor. 1)

       The WF/PC-2 was used to make several internal bias, K-Spot, and
       flat calibration observations to monitor the CCD camera electronics,
       the optical alignment, and for contamination. A total of ten images
       were taken, and they all were reported to be okay.

   1.3 Completed WF/PC-2 5104 (Peculiar and Interacting Galaxies (WC01):
       Cycle 4)

       The WF/PC-2 was used to make images of galaxy 3C405. The OSS
       monitored the observations, and assessed the data quality. Six
       images were received and displayed. Except for a few recenterings
       which did not apparently affect the image quality, they all were
       okay.

   1.4 Completed FOC/96 5524 (FOC Prism Wavelength Calibration: Cycle 4)


       The Faint Object Camera (f/96) was used to attempt to obtain an
       objective prism dispersion curve observation using ultraviolet
       standard star SAND-3 which has an extensive emission line spectrum.
       Two observations were received and displayed. The target was not
       visible in the first observation, and on the second it was reported
       to be at the very edge of the frame. The observation status was
       listed as failed.

   1.5 Completed Three Sets of WF/PC-2 5370 (HST Medium_Deep Survey: Cycle
       4 Medium, High Galactic Latitude)

       The WF/PC-2 was used in parallel with the prime science observations
       to make high galactic latitude observations as part of a medium-deep
       sky survey. The main purpose of these observations is to study the
       evolution and structure of galaxies. Six observations were received
       and displayed in the OSS. One image was reported to show a small but
       sharp change in bias levels in chip PC1. No other anomalies were
       noted.

   1.6 Completed Four Sets of FOC/96 5525 (FOC Neutral Density Filter
       Transmission)

       The Faint Object Camera (f/96) was used to make internal flat
       calibration images using the blue LED to measure its transmission
       curve. F1, F2, and F4 neutral density filters were used. All four
       observations were received and displayed. They were reported to be
       nominal.

   1.7 Completed FGS 5331 (Linking HIPPARCOS to the Extragalactic Reference
       Frame FT0-11, Part 7)

       Fine Guidance Sensor #3 was used to make astrometric observations of
       star 0851+202IN and nearby extragalactic objects which are known to
       have a small angular separation. The observations were monitored.
       The targets were numbered as they were visited. Target 1 ended up
       with a STOP flag and Search Radius Limit Exceeded Flag. Target 2-5
       were locked onto and were held without problems. Target 1 was
       revisited, and again received a STOP flag. Targets 5, 4, 3, and 2
       were revisited, and again they were locked onto it and held. Target
       1 was visited for the last time, and this time it was successfully
       locked onto and held.

   1.8 Completed WF/PC-2 5570 (WF/PC-2 Cycle 4 Calibration: Earth Flats,
       Large Set)

       The WF/PC-2 was used to make a set of Earth flat calibration images
       using different filters in order to construct high quality flat
       fields of the OTA illumination pattern. A total of eight images were
       received and displayed. Two images were reported to be underexposed,
       two were saturated, and four were okay.

   1.9 Completed WF/PC-2 5392 (Mapping Io's Surface and Volcanic Activity:
       Cycle 4 Medium)

       The WF/PC-2 was used to make images of the surface of Jupiter's moon 
Io
       to study changes since the Voyager Mission and before the Galileo
       Mission. The images were reported to be nominal. Four images were
       received and displayed. A fifth image still remains on the science
       tape recorder, and will be analyzed later.

   1.10 Completed Two Sets of FGS 5336 (Linking HIPPARCOS to the
       Extragalactic Reference Frame, NEWHIP-B)

       The Fine Guidance Sensor #3 was  used to make two sets of
       astrometric observations of various objects. These objects
       lie near the apparent position of extragalactic objects. These
       objects will also be observed with the HIPPARCOS satellite. This
       data will be used to determine the systematic rotational offset of
       the reference frame of the HIPPARCOS astrometric satellite. The
       observations were executed as scheduled. No anomalies were reported.

   1.11 Completed FGS 5174 (Astrometric Companion Search: Cycle 4)

       FGS #3 was used to make astrometric observations of the possible
       binary dwarf star BD+67D552 to look for an astrometric unseen low
       mass companion. The OSS monitored the observations and assessed the
       data quality. No anomalies were noted.

   1.12 Completed Two 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. These are randomly chosen fields to sample very low
       luminosity stars in the solar galactic neighborhood, galactic halo
       objects, and distant galaxies. Four images were received and
       displayed. The first two observations encountered some recentering
       events, but were reported to be okay. The last two observations were
       nominal.

   1.13 Completed WF/PC-2 5612 (SMOV WF/PC-2 Decontamination)

       The WF/PC-2 was used to do decontamination operations. Observations
       of standard  A+81D266, and K-Spot observations were also taken. A
       total of nine observations were monitored and displayed. No
       anomalies were noted.

   1.14 Completed WF/PC-2 5484 (Understanding the Geminga (1E0630+178)
       Optical Counterpart: Cycle 4 High)

       The WF/PC-2 was used to make observations of the X-Ray/ Gamma-Ray
       source known as Geminga (aka, 1E0630-178) to study its distance
       and physical characteristics of its emissions. The observations were
       executed as scheduled, and no anomalies were noted.

   1.15 Completed Two Sets of FOC/96 5140 (Observations of the Narrow Line
       Regions in Nearby Seyfert Galaxies)

       The Faint Object Camera (f/96) was used to make observations at
       several different wavelengths of Seyfert galaxies MRK-78 and MRK-3
       which are located near the Cygnus A source. This is to study
       relations between the radio and optical emissions. The OSS monitored
       the observations, and assessed the data quality. Four images were
       reported to be okay, and one image was underexposed.

   1.16 Completed GHRS/2 5506 (The Deuterium Abundance in Moderate Redshift
       QSO Systems)

       The High Resolution spectrograph was used to make observations of
       QSO 0454-220. A wavelength calibration image was also made. A total
       of five observations were received and displayed. Some recentering
       events were reported after a day/night transition. No other
       anomalies were noted.

   1.17 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 plan. The intent is to determine the luminosity function of
       low mass stars and the mass density in the solar neighborhood. The
       images were received as scheduled, and they were reported to look
       okay.

   1.18 Completed WF/PC-2 5563 (WF/PC-2 Cycle 4 Photometric Calibration
       Monitor 1: UV/OPT STD.)

       The WF/PC-2 was used to make photometric calibration images of
       ultraviolet standard star GRW+70D582, and to monitor the photometric
       stability and quantum efficiency of the WF/PC-2. A SIP corrective
       maneuver was successfully uplinked to the spacecraft. Seventeen
       images were reported to look okay, except for one image in which the
       target looked elongated. No other anomalies were noted.

   1.19 Completed GHRS/2 5545 (GHRS Side Two Pulse Height Analysis/Ion
       Test: Cycle 4)

       The High Resolution Spectrograph (Side Two) was used to run a
       standard pulse height analysis (PHA) test on the detectors. This was
       an internal observation, which was used to measure the diode
       response as a function of threshold setting. The OSS monitored the
       observations and assessed the data quality. No anomalies were noted.
