PERIOD COVERED:  0000Z (UTC) 11/29/95 - 0000Z (UTC) 11/30/95

Daily Status Report as of 334/0000Z

1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

1.1 Completed WF/PC-2 6253 (Pure Parallel Archive Program)

       The WF/PC-2 was used to execute a pure parallel program taking =
ultraviolet observations running concurrently with prime science =
observations.  The intent is to search for extra-galactic sources with =
flux excesses at 3000 A0 and galactic sources with excesses at 1600 A0.  =
The observations were completed as planned, and no problems were reported.

1.2 Completed FGS 6036 (Detection and Mass Determination of Low Mass =
Companions to nearby M Dwarf)

       The FGSs were used in both the POS and TRANS Modes to make =
astrometric observations of low mass companions to M class dwarf star =
GL791 and four reference stars.  This will lead to a mass determination =
for the stars.  The observations were completed as planned, and no =
anomalies were noted.

   1.3 Completed WF/PC-2 5913 (Low-Mass Binaries and Luminosity Fuction)

       The WF/PC-2 was used to make observations of the low-mass binary =
system NGP004 (Late Type Class M dwarf stars).  The intent is to determine =
why the local stellar luminosity function is flat below Mv=3D12, while =
that found from more distant stars falls by an order of magnitude by =
Mv=3D14.  The observations were executed as scheduled, and no anomalies =
were noted.

   1.4 Completed WF/PC-2 5968 (Extragalactic Background Light)

       The WF/PC-2 was used to make direct observations of the magnitude =
and color of the diffuse Extragalactic Background Light.  Knowledge of the =
value of the integrated optical flux of this background is of fundamental =
importance to cosmology.  Dark and bias observations were also taken.  The =
observations were completed as planned, and no anomalies were reported.

   1.5 Completed WF/PC-2 6187 (WF/PC-2 Cycle 5 Calibration: Earth Flat)

       The WF/PC-2 was used to make Earth streak, flat calibration images. =
 These streak flats will be used to produce flat fields, to map the OTA =
illumination pattern and, in combination with other data, to produce new =
superflats.  The observations were completed as planned, and no problems =
were reported.

   1.6 Completed WF/PC-2 5972 (Determination of the Extragalactic Distance =
Scale)

       The WF/PC-2 was used to make observations of the galaxy NGC-2541 =
looking for standard candle Cepheid variable stars.  The purpose of these =
observations is to help estimate the Hubble constant with an accuracy of =
10%.  The observations were executed as scheduled, and no anomalies were =
noted.

   1.7 Completed WF/PC-2 5999 (The Nuclear Structure of S0 Galaxies: A PC =
Imaging Survey)

       The WF/PC-2 was used to make observations of S0 class galaxy =
MCG126021 in order to study its nuclear structure.  This is a part of a =
large survey of S0, E/S0, and S0/a class galaxies.  The targets will cover =
a wide range in luminosity and environment.  The observations were =
completed as planned, and no anomalies were noted.

   1.8 Completed FOC/96 6057 (Ultra--High Resolution Studies of AGNs II: =
3C279 Proper Motion)

   The Faint Object Camera (f/96) was used to make ultra-high resolution =
observations of active galactic nuclei in radio galaxy 3C279 in order to =
study the small scale morphology of the AGN.  The data will be searched =
for evidence of superluminal motion, which is known, radio observations, =
and for time variable phenomena. The observations were executed as =
scheduled, and no anomalies were noted.

   1.9 Completed WF/PC-2 5971 (HST Medium Deep Survey)

       The WF/PC-2 was used to make long exposure, medium deep sky survey =
observations at latitudes larger than 10 degrees taken in parallel with =
the prime science observations.  During this proposal, there was a =
one-minute loss-of lock beginning at 333/203639Z which was documented in =
HSTAR 5381.  Otherwise, the observations were executed as scheduled, and =
no anomalies were noted.

   1.10 Completed WF/PC-2 5949 (High Resolution Imaging of Galaxies =
Responsible for QSO Lyman Alpha Absorption.)

       The WF/PC-2 was used to make high resolution observations of Field =
1704 in order to study galaxies which are responsible for intermediate =
redshift QSO Lyman Alpha absorption.  It is the extended gaseous region =
around these galaxies that produces the absorption.  The observations were =
executed as scheduled, and no anomalies were noted.

   1.11 Completed FOS/BL 6243 (Time Resolution Spectroscopy of Nova Cyg)

       The Faint Object Spectrograph (Blue Side) was used to make time =
resolution spectrographic observations of Nova-Cygni 1992.  A 15 minute =
pulsation period, and several transient phenomena have been detected in =
previous observations of this nova. The observations were completed as =
planned, and no problems were reported.

   1.12 Completed WF/P-2 6254 (GTO Pure Parallel Program - Cycle 5)

       The WF/PC-2 was use to make random long exposures of high galactic =
fields taken in parallel with the prime science observations to obtain a =
random sample of galaxies.  The observations were executed as scheduled, =
and no anomalies were noted.
