PERIOD COVERED:  0000Z (UTC) 02/26/96 - 0000Z (UTC) 02/27/96

Daily Status Report as of 058/0000Z

1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

   1.1 Completed Two Sets of WF/PC-2 6363 (The Environments and Host =
Galaxies of BL-Lac Objects)

       The WF/PC-2 was used to make snapshot survey observations to BL-Lac =
object MS1258.4+6 and MS0737.9+7 in order to study their environment and =
their host galaxies.  The goal is to investigate systematic trends in host =
galaxy type, unusual morphological features, nearby companion galaxies, =
etc.  The observations were executed as scheduled, and no anomalies were =
noted.

   1.2 Completed WF/PC-2 5931 (Location of Particle Acceleration in Radio =
Hot Spots)

       The WF/PC-2 was used to make signal-to-noise images  of 3C111-East =
to study the location of particle acceleration in its radio hot spots.  =
Radio hot spots are just one of many locations where active galactic =
nuclei (AGN) phenomena imply the presence of ultra-relativistic particles. =
 The observations were completed as scheduled, and no problems were =
reported.

   1.3 Completed Two Sets of WF/PC-2 6188 (WF/PC-2 Cycle 5 Calibration: =
Dark)

       The WF/PC-2 was used to make internal dark calibration images.  The =
observations were completed as scheduled, and no problems were reported.

   1.4 Completed FOC/96 6306 (Supernova Light Echoes)

       The Faint Object Camera(f/96) was used to make observations of =
supernovae remnant SN1979C in order to study its light echoes.  Measuring =
the separation of the echo from the site of the supernova gives a direct =
measure of the distance to the parent galaxy.  The echoes are expected to =
be very blue, and highly polarized.  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 5913 (Low-Mass Binaries and Luminosity Fuction)

       The WF/PC-2 was used to make observations of the low-mass binary =
system NGP005 (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.

   1.7 Completed WF/PC-2 5924 (Nuclear Emission Line Region Associated =
with Compact Flat Spectrum)

       The WF/PC-2 was used to make spectrographic observations of the =
nuclear emission region of galaxy NGC-5077 to study its compact flat =
spectrum.  There is evidence that this jet-produced AGN is powered by =
accretion disks feeding massive black hole.  The observations were =
executed as schedule, and no anomalies were noted.

   2.3 Operations Notes: 

       All of the missing science data on ESTR #1, discussed in =
yesterday's report, was eventually recovered.

3.0 SIGNIFICANT FORTHCOMING EVENTS: 

        Nothing at this time.
