DAILY REPORT #1845

PERIOD COVERED: 0000Z (UTC) 03/28/97 - 0000Z (UTC) 03/31/97

Daily Status Report as of 090/0000Z

1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

1.1 Completed Two Sets of NIC/1/2/3 7042 (NICMOS Fine Optical =
Alignment)

The Near-Infrared Camera #1 was used to make observations of =
NGC-3603 in order to obtain fine optical alignment calibration =
measurements. This is to perform a series of iterative adjustments of the=
NICMOS pupil alignment mechanism to establish the initial optical =
alignment in focus and tilt. A dark calibration image was also taken. =
The observations were executed as scheduled, and no anomalies were noted. =


1.2 Completed Three Sets of WF/PC-2 7019 (WF/PC-2 SMOV Flat Field =
Check)

The WF/PC-2 was used to obtain a sequences of Earth streak and =
internal flats to check for changes at the 1% level. The observations =
were completed as scheduled, and no problems were reported

1.3 Completed WF/PC-2 6344 (Low - Mass Binaries in the Hyades - =
Completing the Survey)

The WF/PC-2 was used to make observations of the low mass binary =
star RHY242 (M-Class dwarf stars) which is located in the Hyades Cluster. =
The observations were executed as scheduled, and no anomalies were =
noted.

1.4 Completed Two Sets of WF/PC-2 6419 (Testing Unified Models With a =
Complete Sample of Seyfert Galaxies)

The WF/PC-2 was used to make observations of the Seyfert galaxies =
ESO137-G34 and NGC-5273 to help build a complete survey of the Seyfert =
class of galaxies. This will help test the current model for Seyfert =
class galaxies. This model proposes that all Seyferts have Seyfert-1 =
nucleus, which is surrounded by a torus of gas and dust. The =
observations were completed as planned and no anomalies were noted.

1.5 Completed WF/PC-2 6359 (Core Properties of the Bulges of Spiral =
Galaxies)

The WF/PC-2 was used to make snapshot survey observations of =
spiral galaxy NGC-6810 in order to study its central bulges. The aim is =
to investigate the core properties, correlations with global galactic =
properties, and the frequency of occurrence of multiple and/or =
miscentered nuclei. The observations were completed as scheduled, and no =
anomalies were noted.

1.6 Completed STIS/CCD 7063 (STIS SMOV CCD Contamination Monitor)

The Space Telescope Imaging Spectrograph CCD was used to make =
observations of standard star GD153 in order to measure flux and look =
for any gross changes over time that might indicate contamination. A =
wavelength calibration image was also taken. The observations were =
completed as scheduled, and no anomalies were reported.

1.7 Completed Four Sets of WF/PC-2 6361 (High Resolution Imaging of =
X-Ray Selected AGNs)

The WF/PC-2 was used to make high resolution observations of the =
known, low, red-shifted, x-ray active galactic nuclei (AGN) MS1158.6-0, =
MS1242.2+1, 1456.4+2, MS1426.5+0 and MS2039.5-0. These data will allow a =
study of the optical properties of an unbiased sample of AGN host =
galaxies. The observations were completed as scheduled, and no problems =
were reported.

1.8 Completed WF/PC-2 6633 (Cusps or Cores in Barred Bulges?)

The WF/PC-2 was used to make observations of the SB class (Barred) =
galaxy NGC-6684 in order to study its nuclear bulge region and cusps. =
This is a highly tri-axial, tumbling, low-mass stellar system. The =
observations were completed as planned, and no problems were reported.

1.9 Completed WF/PC-2 6491 (The Optical Structure and Environments of =
Z~1 3CR Quasars)

The WF/PC-2 was used to make observations of radio galaxy/quasar =
3C287 in order to study its optical stricture and environments. This =
should obtain better statistics on correlations seen in the Cycle 4 data, =
such as the association of linear galaxies with other 3CR galaxies and =
quasars. The observations were executed as scheduled, and no anomalies =
were noted.

1.10 Completed Two Sets of WF/PC-2 6887 (A Photometric Search for =
Faint Companions to Nearby Stars)

The WF/PC-2 was used to make photometric search observations of =
the nearby stars Proxima-Cen and WOLF359 in order to look for possible =
companions. The technique involves use of the planetary camera with wide =
band pass filters to photometrically measure for the presence of resolved =
dark companions. The observations were executed as scheduled, and no =
anomalies were noted.

1.11 Completed STIS/CCD 7121 (Imaging Spectroscopy of NGC-4151)

The Space Telescope Infrared Spectrograph CCD was used to make =
observations of NGC-4151 which is the brightest Seyfert 1 galaxy and thus =
a perfect target to demonstrate the imaging spectroscopy capabilities of =
STIS. A wavelength calibration image was also taken. The observations =
were executed as scheduled, and no anomalies were noted.
Wave

1.12 Completed WF/PC-2 6677 (The Origin of the X-Ray Background: What =
are the Faintest X-Ray Galaxies?)

The WF/PC-2 was used to make observations of the galaxy GAL-133409 =
which is from the deepest optically identified (ROSAT) X-ray survey yet. =
These images were taken to determine the morphologies of the remaining =
systems which we cannot study from the ground in order to determine =
whether the remaining non-QSO XRB might be explained by emission from =
interacting or disturbed spirals. The observations were completed as =
planned, and no anomalies were reported.

1.13 Completed FOC/96 7012 (FOC/96 Baseline Throughput)

The Faint Object Camera (f/96) was used to measure the absolute =
sensitivity without in the COSTAR beam. Observations were made using =
standard star GRW+70D582. This was done to provide an estimate of the =
degradation of the FOC sensitivity over the three years since the first =
servicing mission, when an identical set of measurements were taken. The =
observations were executed as scheduled, and no anomalies were noted.

1.14 Completed Four Sets of WF/PC-2 6741 (Synoptic Monitoring of =
Seasonal Phenomena on Mars)

The WF/PC-2 was used to make observations of the planet Mars as =
part of a program of synoptic monitoring of the planet's seasonal =
phenomena. This is an especially important period because Mars =
Pathfinder and Mars Global Surveyor will be in cruise phase during this =
time. The observations were executed as scheduled, and no anomalies were =
reported.

1.15 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 of =
BL-Lac object 1ES0715-25 in order to study its environment and its 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.

1.16 Completed FGS 6472 (Dynamical Masses for the Stars in the =
Pre-Main-Sequence Classification)

FGS #3 was used in both the TRANS and POS to make astrometric =
observations of the pre-main-sequence, binary system star STAR-04560 =
(aka, 045251+3016). These data will be used to measure its dynamical =
mass ratio of the pair, and the inclination of their orbits. The =
observations were executed as scheduled, and no anomalies were noted.

1.17 Completed WF/PC-2 6852 (The Martian Surface and Atmosphere)

The WF/PC-2 was used to make high-resolution observations of the =
planet Mars and its surface and atmosphere just before (or during) the =
March 1997 opposition. These observations employed PC exposures with =
full-aperture filters, the methane quad filter, and linear ramp filters. =
The observations were executed as scheduled, and no anonmalies were =
noted.

1.18 Completed WF/PC-2 6587 (Black Holes and Cores of Early-Type =
Galaxies)

The WF/PC-2 was used to make observations of early-type galaxy =
NGC-3842 in order to study its nuclear core region and its possible black =
hole. The campaign to find black holes in the centers of galaxies using =
HST has so far been highly successful. The observations were completed =
as planned, and no problems were reported.
