1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

   1.1 Completed Two Sets of WFC 3848 (Separate Light Curves of Pluto and 
       Charon)

       The Wide field Camera was used to make two sets of two observations
       each. One set of the planet Pluto, and the other set of its moon
       Charon (Each individually). The observations were obtained while
       Pluto and Charon were within 25 Arcseconds of a comparison star. All
       four images were reported to look satisfactory. 

   1.2 Completed PC 3763 (Synoptic Monitoring of Seasonal Phenomena on Mars)

       The Planetary Camera was used to make atmospheric and surface
       observations of the Planet Mars looking for seasonal variations.
       There is a change that there might be dust storms in the northern
       hemisphere. Three images were taken, and they were reported to be
       satisfactory. 

   1.3 Completed PC 4929 (WF/PC Cycle 2: Improved Dark Calibration)

       The Planetary Camera was used to make two dark calibration images.
       The observations were 1200 seconds exposures, and the camera were
       pre-flashed. The dark images were reported to be normal. 

   1.4 Completed FGS 4031 (High Speed Photometry - A Search for Planetary 
       Companions)

       The Fine Guidance Sensors were used to make astrometric observations
       of the star Proxima Centauri to determine the presence of a Jupiter
       sized planet in orbit about the target star from the position
       perturbations caused by the planet. The astrometric observations
       were monitored by the OSS. No problems were reported with the
       telemetry. 

   1.5 Uplinked Updated Ephemeris Tables, Per MOSES 2871

       Uplinked at 168/0031Z. All Okay.

   1.6 Completed FOC/96 3594 (Imaging Polarization of the M-87 Nucleus and 
       Jet)

       The Faint Object Camera (f/96) was used to make images in polarized
       light of the jet and inner nuclear regions of galaxy M-87 (aka,
       NGC-4486). The goal was to map the distribution of polarization in
       the jet and to measure the polarization of the nucleus at
       ultraviolet and optical wavelenghts. The first image was received in
       real-time, and a corrective maneuver was calculated and successfully
       uplinked to the spacecraft. Most of the observations still remain on
       the science tape recorder. No problems were reported. 

   1.7 Completed WFC 3917 (HST Medium Deep Survey: Cycle 2 Part 1)

       The Wide Field Camera was used to make several medium-deep sky
       survey images taken in parallel with the prime science observations.
       The observations were executed as scheduled, and no problems were
       reported.

   2.4 Operations Note: 

       Simulation #3 (i.e., EVA Simulation Day 2 - Solar array Deploy) was
       successfully completed yesterday in the MOR. This simulation was
       conducted in parallel with the astronauts working in the zero-g
       simulator tank located at MSFC.
