HUBBLE SPACE TELESCOPE
DAILY REPORT #1188

PERIOD COVERED: 0700 EST
Daily Status Report as of 207/1200Z.

1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

1.1 Completed WF/PC-2 5562 (WF/PC-2 Cycle 4 Calibration: Internal
Monitor. 1)

The WF/PC-2 was used to obtain a 30-minute long, dark exposure to
provide ongoing calibration of the CCD dark current and to monitor
and characterize the evolution of hot pixels. The image was received
and displayed in the OSS, and it was reported to look okay.

1.2 Completed WF/PC-2 5663 (WF/PC-2 cycle 4: Photometric Calibration
Monitor: Fields Part 2)

The WF/PC-2 was used to make observations of globular Cluster
NGC-5139 with various filters in order to check the photometric
calibration of the WF/PC-2. Ten observations were received and
displayed in the OSS. They all were reported to look okay. One data
packet was missing the Standard Header Packed (SHP) due to data
being split between two tape recorder dumps.

1.3 Completed Three of WF/PC-2 5655 (WF/PC-2 cycle 4 calibration:
Internal Monitor-2 - Flats Part 2)

The WF/PC-2 was used to make both dark and visual flats. Two dark
images were received and displayed. They both were reported to be
nominal. The visual flat observation was executed as scheduled, and
no anomalies were noted.

1.4 Completed WF/PC-2 5342 (UV Imaging of Intermediate-
Age Magellanic Cloud Clusters)

The WF/PC-2 was used to make ultraviolet observations of the star
cluster NGC-1856 which is located in the Large Magellanic Cloud t
determine the nature of its hot stellar components. Three
observations were received and displayed. They were reported to be
okay.

1.5 Completed FGS 5338 (Linking the HIPPARCOS to the Extragalactic
Reference Frame: NEWHIP-D)

The FGSs were used to make astrometric observations of the
extra-galactic objects NEWEHIP-62, NEWEGOD-62, and objects 1020-REF,
and 1021-REF . These observations are to help tie the HIPPARCOS and
extra-galactic reference frames together. The astrometric
observations occurred during LOS, and they could not be monitored.
No anomalies were noted.

1.6 Completed WF/PC-2 5370 (HST Medium-Deep Survey: Cycle 4 Medium, High
Galactic Latitude)

The WF/PC-2 was used in parallel with the prime science observations
to make high galactic latitude observations as part of a medium-deep
sky survey. Two observations were received and displayed in the OSS.
They both were reported to be okay.

1.7 Completed WF/PC-2 5476 (Continuum Snapshots of 3CR Radio Galaxies)

The WF/PC-2 was used to make snapshot images of radio galaxy 3C252.0
as part of a continuum survey and to study the galaxy's morphology.
Three images were received and displayed. They were reported to look
okay.

1.8 Completed WF/PC-2 5563 (WF/PC-2 Cycle 4 Photometric Calibration
Monitor 1: UV/OPT STD.)

The WF/PC-2 was used to make photometric calibration images of
ultraviolet standard star GRW+70D582 and monitor the photometric
stability and quantum efficiency of the WF/PC-2. Eighteen images
were taken and displayed. They all were reported to be okay.

1.9 Completed WF/PC-2 5395 (High Spatial Resolution Imaging of Pre-main
Sequence Binary Stars:)

The WF/PC-2 was used to make ultraviolet observations of pre-main
sequence binary star GG-Tau. Four observations were received and
displayed. They all were reported to be okay.

1.10 Completed WF/PC-2 5560 (WF/PC-2 cycle 4 calibration: Internal
Monitor. 1)

The WF/PC-2 was used to make several internal bias, K-Spot, and flat
calibration observations to monitor the CCD camera electronics, the
optical alignment, and to check for contamination. The observations
were executed as scheduled, and no anomalies were noted.

1.11 Completed FOS/RD 5451 (The Absorption Cross-sections of Nearby
Galaxies)

The Faint Object Spectrograph (Red Side) was used to observe light
from quasi-stellar object 0454+0356, which acts as a probe as it
passes through the outer reaches of a nearby galaxy. The binary
search was received in real-time, and it looked okay. No anomalies
were noted.

1.12 Completed WF/PC-2 5369 (HST Medium-Deep Survey: Cycle 4 Medium,
High Galactic Latitude)

The WF/PC-2 made a series of observations of high latitude objects
as part of a medium deep sky survey. The observations were taken in
parallel with other prime science observations. The observations
were executed as scheduled, and no anomalies were noted.

1.13 Completed FOS/RD 5588 (FOS Prism Snapshot Survey)

The Faint Object Spectrograph (Red Side) was used to make a Prism
observation of quasi-stellar object 0454+0356 to study its optical
to ultraviolet continuum shape. The observations were executed as
scheduled, and no anomalies were noted.

1.14 Completed WF/PC-2 5446 (The Nuclei of Nearby S0 and Spiral
Galaxies)

The WF/PC-2 was used to make observations of galaxy IC-750. The
observations were executed as scheduled, and no anomalies were
noted.

1.15 Completed WF/PC-2 5427 (Calibration of Nearby Galaxy Type IA
Supernovae as Standard Candles)

The WF/PC-2 was used to make observations of nearby galaxies
NGC-4496-A-F and NGC-4536 as part of an effort to find Cepheids in
these galaxies which have produced a Type I supernova. The
observations were executed as scheduled, and no anomalies were
noted.
