HUBBLE SPACE TELESCOPE

DAILY REPORT #1869

PERIOD COVERED: 0000Z (UTC) 05/01/97 - 0000Z (UTC) 05/02/97

Daily Status Report as of 122/0000Z

1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

1.1 Completed Three Sets of WF/PC-2 6909 (WF/PC-2 Cycle 6 Calibration:
Earth Flats

The WF/PC-2 was used to make observations of the bright Earth to
obtain streak flats which are used to construct high quality flat fields
for the WF/PC-2 filter set. The observations were executed as scheduled,
and no anomalies were noted.

1.2 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 waveline
calibration observation was also completed. The observations were
completed as scheduled, and no anomalies were reported.

1.3 Completed Four Sets of WF/PC-2 7553 (Pure Parallel Archive Survey II)

WF/PC-2 parallel observations were obtained in the ultraviolet in
search for interesting objects. This program is designed to find
extragalactic sources with near ultraviolet excesses (3000 A0) outside the
galactic plane and far ultraviolet sources (1600 A0) in the galactic plane.
The procedure was executed as scheduled, and no anomalies were reported.

1.4 Completed Three Sets of NIC/1/2/3 7048 (NICMOS Parallel Thermal
Background Test)

The Near Infrared Cameras (Cameras One, Two and Three) were used to
make observations of an object designated as Target-1 in order execute
measurements of the stability of the HST thermal emissions. The
observations were executed as scheduled, and no problems were reported.

1.5 Completed WF/PC-2 6496 (Nuclear Rings: Probing the Hearts of Barred
Galaxies)

The WF/PC-2 was used to make observations of the barred class galaxy
ESO565-11 in order to study its inner nuclear region and "Nuclear Rings"
structure. These small rings, less than 10'' in angular radius, are
thought to trace the location of the inner Lindblad resonance (ILR), a 2:1
orbital resonance with the bar, that is of great importance to the
structure and evolution of disk galaxies. The observations were completed
as planned, and no anomalies were reported.

1.6 Completed WF/PC-2 6346 (Snapshot Survey of the Ultraluminous IRAS
Galaxy Sample-Part 1 High)

The WF/PC-2 was used to make snapshot survey observations of the
ultraluminous IRAS galaxy QDOTULIR10. These data will be searched for
multiple cores, which imply a merger has occurred, and for starburst
regions. The observations were executed as scheduled, and no anomalies
were noted.

1.7 Completed FGS 6878 (Parallax of NGC-6853)

The Fine Guidance Sensors were used to make astrometric observations
of stars located in NGC-6853. NGC 6853 is one of the closest planetary
nebulae. Its trigonometric parallax is presently only poorly known. HST
observations have the potential to reduce the parallax uncertainty to about
0.0005 arcsec. The observations were completed as scheduled, and no
anomalies were reported.

1.8 Completed WF/PC-2 6905 (WF/PC-2 Cycle 6 Calibration: Internal Monitor)

The WF/PC-2 was used to make several internal calibrations
observations, including biases and internal flats, as part of a Cycle 6
calibrations procedure. A variety of internal exposures are run weekly to
verify and monitor the health of the camera. The observations were
executed as scheduled, and no anomalies were noted.

1.9 Completed Two Sets of FGS 7027 (Near Term Stability Monitor For FGS1R)

The Fine Guidance Sensor (1-R) was used to make astrometric
observations of the reference stars OF49, OF56, OF 42, (et al.) in order to
monitor its near term stability. The goals are threefold: (1) to establish
the baseline long term stability measurement for the new FGS and monitor
changes in the relative plate scale and distortion since the SMOV
Mini-OFAD; (2) to monitor changes in the transfer function on an orbital
timescale and over weeks; (3) to monitor desorption changes in the position
of the ITS. The observations were executed as scheduled, and no anomalies
were noted.

1.10 Completed STIS/MA1/S/C 7105 (STIS MAMA Turn-on)

The STIS/MA1 was successfully turned on. This will be the first
high-voltage ramp-up of the far-ultraviolet and near-ultraviolet MAMA
detectors. The operations was executed as scheduled, and no anomalies were
noted.

1.11 Completed Three Sets of WF/PC-2 6802 (Cosmology With the Medium
Deep Survey)

The WF/PC-2 was used to make observations taken in parallel with the
prime science observations as part of the Medium Deep Sky Survey. The
observations were executed as scheduled, and no problems were reported.

1.12 Completed Two Sets of WF/PC-2 6904 (WF/PC-2 Cycle 6 Calibration: Darks)

The WF/PC-2 was used to make a series of several dark calibration
images as part of a standard calibration within Cycle 6. This calibration
procedure is performed once per week as part of an on going CCD calibration
to be used to monitor and characterize hot pixels. The observations were
executed as scheduled, and no anomalies were noted.

1.13 Completed WF/PC-2 6906 (WF/PC-2 Cycle 6 Calibration: Internal
Monitor-Visual Flats)

The WF/PC-2 was used to make internal calibration, visual flat
images as part of the Cycle 6 internal monitoring of the instrument's
operations. This proposal defines the standard series of internal flat
fields, which will be executed twice per month. The observations were
completed as planned, and no anomalies were reported.
