HUBBLE SPACE TELESCOPE

                       DAILY REPORT #1518

PERIOD COVERED:  0000Z (UTC) 11/15/95 - 0000Z (UTC) 11/16/95

Daily Status Report as of 320/0000Z

1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

1.1 Completed Two Sets of FOS/RD 6163 (Focus, X-Pitch and Y-Pitch)

       The Faint Object Spectrograph (Red Side) was used to determine the =
proper values to set for the FOS high voltage, and the X and Y pitch.  The =
observations were executed as scheduled, and no anomalies were noted.

1.2 Completed GHRS/1/2 5870 ("Maunder Minimum" Stars)

       The High Resolution Spectrograph (Sides One and Two) was used to =
make far ultraviolet observations of solar type star HD3651.  This star =
exhibits weak, non-variable Ca II emission and a long rotation period.  =
The implication is that this star may have a weak magnetic field and =
undergoing a "Maunder Minimum".  The observations were executed as =
scheduled, and no anomalies were noted.

1.3 Completed Two Sets of FOS/RD 6236 (FOS Cycle 5: Location of Spectra =
and Wavelength Calibration: Red Side Detector)

       The Faint Object Spectrograph (Red Side) was used to make =
calibration observations in order to determine the location of the spectra =
and to perform a wavelength calibration.  All observations were internal.  =
A Taled calibration was also completed.  The observations were completed =
as planned, and no anomalies were reported.

1.4 Completed Two Sets of WF/PC-2 6183 (WF/PC-2 Cycle 5 Calibration: =
Decon)

   The WF/PC-2 was used to make some internal flat, K-Spot, and dark =
calibration images.  The purpose is to define decontamination procedures =
to be run during Cycle 5.  The calibration observations were completed as =
scheduled, and no anomalies were reported.

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

       The WF/PC-2 was used to make observations of the galaxy NGC-2541 =
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.

1.6 Completed WF/PC-2 5987 (X-Ray Luminous Clusters of Galaxies)

       The WF/PC-2 was used to obtain images of distant clusters of =
galaxies.  These clusters were chosen since they are x-ray luminous.  The =
observations were executed as scheduled, and no anomalies were noted.

1.7 Completed WF/PC-2 6187 (WF/PC-2 Cycle 5 Calibration: Earth Flats)

       The WF/PC-2 was used to make Earth streak flat calibration images.  =
These streak flats will be used to produce flat fields, to map the OTA =
illumination pattern and, in combination with other data, to produce new =
superflats.  The observations were completed as planned, and no problems =
were reported.

1.8 Competed WF/PC-2 5982 (Imaging of a Complete Sample of the Nearest =
Infrared Quasars)

       The WF/PC-2 was used to make two color observations of the nearby =
infrared quasar (IR QSO) IRAS08572.  It is believed that this IR QSO =
resulted from the merger of two gas-rich galaxies.  The observations were =
executed as planned, and no anomalies were reported.

1.9 Completed WF/PC-2 5978 (Host Galaxy of Distant Radio Quasars)

        The WF/PC-2 was used to make observations of the host galaxy of =
distant radio-loud quasar QSO-1026+4.  The observations were executed as =
scheduled, and no anomalies were noted.

                          Scheduled Reacquisitions : 5
                                        Successful : 5

   2.2 FHST Updates: 

                              Scheduled : 17

       The FHST update scheduled at 319/1306Z failed.

   2.3 Operations Notes: 

       The regular checkout of the backup SAMS facility was performed this =
morning, with no significant problems reported.
