HUBBLE SPACE TELESCOPE

DAILY REPORT #2033

PERIOD COVERED: 0000Z (UTC) 01/05/98 - 0000Z (UTC) 01/06/98

Daily Status Report as of 006/0000Z

1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

1.1 Completed WF/PC-2 7618 (WF/PC-2 Cycle 7 Photometric Monitor UV/OPT STD)

The WF/PC-2 was used to make observations of the standard star
GRW+70D582 as part of a Cycle 7 photometric monitoring program. This
ultraviolet spectrophotometric standard star was observed in a variety of
filters and cameras to monitor the photometric stability and quantum
efficiency of WF/PC-2 from the far-ultraviolet to near-infrared. The
observations were completed as scheduled, and no problems were reported.

1.2 Completed STIS/CCD 7802 (Daily Darks to Update Acquisition Bad Pixel
Table)

The Space Telescope Imaging Spectrograph (CCD) was used to make
calibration observations to obtain daily darks to update the acquisition
bad pixel table. These darks are intended to identify hot pixels for
update to the acquisition on-board FSW hot pixel table. Daily hot pixel
lists can also be used for science data analysis. The observations were
executed as scheduled, and no anomalies were noted.

1.3 Completed Five Sets of STIS/CCD 7783 (STIS Parallel Science)

The Space Telescope Imaging Spectrograph (CCD) was used to make
observations taken in parallel with the prime science. The observations
were completed, and no problems were reported.

1.4 Completed Two Sets of WF/PC-2 7621 (WF/PC-2 Cycle 7 Supplemental
Darks PT1/3)

The WF/PC-2 was used to make supplemental dark calibration images.
This set of calibrations is intended to obtain three dark frames every day
to provide data for monitoring and characterizing the evolution of hot
pixels. The observations were executed as scheduled, and no anomalies were
noted.

1.5 Completed Four Sets of WF/PC-2 7620 (WF/PC-2 Cycle 7 Standard Darks)

The WF/PC-2 was used to make a series of Cycle 7 standard dark
calibration images. This dark calibration program obtains dark frames
every week in order to provide data for the ongoing calibration of the CCD
dark current rate, and to monitor and characterize the evolution of hot
pixels. The observations were executed as scheduled, and no anomalies were
noted.

1.6 Completed STIS/CCD/MA2 7347 (Direct Imaging of Betelgeuse)

The Space Telescope Imaging Spectrograph (CCD and MA2) was used to
make observations of the super giant star Betelgeuse HD39801 (a.k.a.,
BD+75D325 or Alpha Orionis). Our UV images of Alpha Orionis obtained with
the FOC in 1995 {Cycle 5} are the first direct images of the surface of a
star other than the Sun. The observations were completed as planned, and
no anomalies were reported.

1.7 Completed WF/PC-2 7625 (WF/PC-2 Cycle 7 Earth Flats)

The WF/PC-2 was used to make a series of Earth flat calibration
images. These flat fields will allow mapping of the OTA illumination
pattern and will be used in conjunction with previous internal and external
flats to generate new pipeline superflats. The observations were completed
as planned, and no anomalies were reported.

1.8 Completed Five Sets of WF/PC-2 7786 (Pure Parallel Archive Survey -
Continuation)

The WF/PC-2 was used to make observations as part of an archival
survey program in which the images were taken in parallel with the prime
science observations. These WF/PC-2 parallel observations were obtained in
the ultraviolet in a search for interesting objects. The observations were
completed as planned, and no problems were reported.

1.9 Completed Two Sets of STIS/MA2 7604 (Cycle 7 MAMA Dark Measurements)

The Space Telescope Imaging Spectrograph (MA2) was used to make MAMA
dark measurements. These darks will be used in later image reductions and
also trended over the instrument's life time as an indicator of the
detector's degradation or damage. The observations were completed as
scheduled, and no problems were reported.

1.10 Completed Three Sets of WF/PC-2 7336 (Cosmological Parameters Omega
and Lambda From High-Redshift Type Ia Supernovae)

The WF/PC-2 was used to make observations of the high redshifted
Type Ia supernovae SN94-8H-Z0, SN91-5H-Z0 and SN95-8H-Z0. HST can make a
direct measurement of the cosmological parameters, Omega, Lambda, and
curvature using Type Ia supernovae as calibrated "standard candles." The
observations were executed as scheduled, and no anomalies were noted.

1.11 Completed STIS/CCD 7782 (STIS Non-Scripted Parallel Archive
Proposal - Half Orbit)

The Space Telescope Imaging Spectrograph (CCD) was used for a
non-scripted parallel archive proposal (one-half orbit). The observations
were executed as scheduled, and no anomalies were noted.

1.12 Completed Two Sets of STIS/CCD 7781 (STIS Non-Scripted Parallel
Archive Proposal - Full Orbit)

The Space Telescope Imaging Spectrograph (CCD) was used for a
non-scripted parallel archive proposal (one full orbit). The observations
were executed as scheduled, and no anomalies were noted.

1.13 Completed NIC/2 7495 (Survey of Gravitational Lenses as
Cosmological Tools)

The Near Infrared Camera (Camera Two) was used to make survey
observations of object MG1131+045by obtaining deep, high-resolution images
in the optical and near IR in order to see if it is gravitational lenses
and could be used as a cosmological tool. The observations were executed
as scheduled, and no anomalies were noted.

1.14 Completed WF/PC-2 7203 (Cosmology with the Medium Deep Survey -
Short Orbit Cases)

The WF/PC-2 was used to take short (about 20 minute) exposures, to
be taken in parallel with the prime science observations, using the "I"
filter. These exposures are part of the medium-deep survey, which
emphasizes exposures that will be useful in obtaining cosmological
parameters. The observations were completed as planned, and no problems
were reported.
