HUBBLE SPACE TELESCOPE

DAILY REPORT #1542

PERIOD COVERED: 0000Z (UTC) 12/21/95 - 0000Z (UTC) 12/22/95

Daily Status Report as of 356/0000Z

1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

1.1 Completed FOS/RD 6339 (Verification of the UV Spectrum of the HST =
Background Light )

The Faint Object Spectrograph (Red Side) was used to make =
ultraviolet observations of the HST background light. These FOS =
observations were taken parallel to Hubble Deep field (HDF) survey. Both =
the HDF and these FOS data will be used to test and improve the existing =
engineering model of the HST background light. The observations were =
completed as planned, and no anomalies were reported.

1.2 Completed WF/PC-2 5972 (Determination of the Extragalactic Distance =
Scale)

The WF/PC-2 was used to make observations of the galaxy NGC-3198 =
looking for standard candle Cepheid variable stars. The purpose of this =
observations is to help estimate the Hubble constant with an accuracy of =
10%. The observations were executed as scheduled, and no anomalies were =
noted.

1.3 Completed WF/PC-2 6189 (WF/PC-2 Cycle 5 Calibration: Internal =
Monitor - Vis Flats)

The WF/PC-2 was used to make internal visual flat calibration =
images. Both photometric and narrow-band filters were used. The =
observations were executed as planned, and no problems were reported.

1.4 Completed WF/PC-2 6337 (The Hubble Deep Field Observations)

The WF/PC-2 were used to take the Hubble Deep Field (HDF) images. =
This project consists of hundreds of long WF/PC-2 exposures of the high =
galactic latitude field (HDF-123646), taken in eight visits. A dark =
calibration image was also taken. The observations were completed as =
planned, and no problems were reported.

1.5 Completed FOS/RD 6342 (The Spectrum of Background Light)

The Faint Object Spectrograph (Red Side) was used to make =
spectrographic observations of back ground light. These observations were =
taken in parallel during portions of the Hubble Deep Field (HDF) survey. =
The data will be used to measure the extragalactic background light (EBL). =
The observations were executed as scheduled, and no anomalies were noted.

3.0 SIGNIFICANT FORTHCOMING EVENTS:

Over the upcoming Christmas through New Year's Holidays this Daily =
Report will be produced on Dec. 27 (Wednesday) and Dec. 28 (Thursday) =
only. Regular coverage will pick up again of Jan. 02, 1996.
