1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

   1.1 Completed WFC 2438 (Study of the Most Distant Galaxies)

       The Wide Field Camera was used to make six images of the high red
       shifted galaxy 4C41.17 using a red shifted Lyman Alpha and a
       continuum filter. All six images were received and displayed. The
       first image showed one packet of data missing. The Data Capture 
       Facility (DCF) reported that the frame sync patterns were off by as
       much a six bits. The packet was reported to be unrecoverable, and
       the problem could be due to transmission errors anywhere downstream
       of the TDRSS satellite. All of the other images were received and
       displayed. They were reported to look okay. 

   1.2 Completed GHRS/2 3755 (Absorption Cross Sections of Nearby Galaxies)

       The High Resolution Spectrograph was used to observe quasi-stellar
       object 0637-752. This object was used as a probe to study the
       absorption lines produced by the halo of a foreground galaxy. The
       return to brightness spiral search was executed in course track with
       no problems, and the target was found in the sixth map. A status
       buffer error message was received during an LOS which indicated that
       there had been a failure to position the carousel. An HSTAR was
       written. The observation was restarted after the reacquisition, and
       went well. In a subsequent observation one packet of data was
       scrambled. Preliminary analysis indicated that this is the same
       problem which was reported in section 1.1 . The other observations
       were reported to be okay. 

   1.3 Completed PC 4714 (Internal Delta Flats)

       The Planetary Camera was used to make a single internal flat
       observation. This image will be used for the restoration of Earth
       flats, which were altered due to changes in the quantum efficiency
       which occurred after WFPC decontamination operations. The
       observations was reported to be okay. 

   1.4 Completed FOS/BL 4110 (The Physics of Massive O-type Stars)

       The Faint Object Spectrograph was used to make observations of OB
       Class star HD141556 which is located in the Large Magellanic Cloud.
       The observations were executed as scheduled, and no problems were
       reported.

   2.4 Operations Note: 

       The third Servicing Mission Internal Simulation (aka. EVA Sim. #1)
       was completed yesterday (Wednesday, Jan.14) from 014/1300 through
       014/2300Z. This simulation covered the time line from the Solar
       Array Primary Deployment Motor (PDM) event through the conclusion of
       EVA #1. This simulation provided the HST Servicing Mission team
       with functional training to ensure operational readiness. The test 
       went well, and no major problems were reported. 

       Commands were sent to the PSEA configuration memory to revert back
       to the original MSS configuration. The MSS reasonableness test has
       been reactivated so the PSEA will automatically select MSS 2 if the
       MSS 1 signals are out of limits. Since both MSSs have exhibited
       anomalous signatures at times, there is no longer a strong reason to
       pre-select the MSS to be used. The new configuration gives the PSEA
       maximum flexibility in selection an MSS.
