PERIOD COVERED:  0000Z (UTC) 07/18/96 - 0000Z (UTC) 07/19/96

Daily Status Report as of 201/0000Z

1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

   1.1 Completed FOS/RD 6577 (An Expanded Survey for Study of the =
Lyman-Alpha Line and QSO Mg II Absorption)

       The Faint Object Spectrograph (Red Side) was used to make =
observations of the QSO PKS0421+01 in order to make a survey of the =
Lyman-Alpha line and the 68 Mg II absorption line system.  The =
observations were completed as scheduled, and no problems were reported. 

   1.2 Completed Three 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 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.

   1.3 Completed GHRS/2 6782 (Testing the Theory of Radiative Levitation =
in DA White Dwarfs)

       The High Resolution Spectrograph (Side Two) was used to make =
observations of the DA white dwarf star REJ1614-08 in order to test the =
theory of radiative levitation.  This theory predicts that for high =
enough temperatures, the radiation pressure should prevent elements =
heavier than H or He from sinking out of the atmosphere of the star.  A =
wave length calibration image was also taken.  The observations were =
completed as planned, and no anomalies were reported.

   1.4 Completed Two Sets of WF/PC-2 6630 (The Nucleus of Comet 22P/Kopff =
and Its Dust Gas Emissions)

       The WF/PC-2 was used to make observations of the periodic comet =
22P/Kopff in order to study the nucleus of the comet and its dust =
emissions.  At the minimum geocentric distance, the spatial resolution =
will be about 38 KM, allowing the nucleus to be distinguished from the =
coma.  The observations were executed as scheduled, and no anomalies were =
noted.

   1.5 Completed FOS/BL 6470 (Decoding the Inner Dsik About =
Beta-Pictoris)

       The Faint Object Spectrograph (Blue Side) was used to make =
ultraviolet spectrographic observations of the disk around the star Beta =
Pictoris (aka, HD39060) looking for emission lines arising in the inner =
disk.  The objective is to ascertain the composition of the inner disk.  =
The observations were completed as planned, and no problems were =
reported.

                             Successful : 10

   2.3 Operations Notes: 

       There were no reported operational problems, as the HST returned =
to normal science operations.
