PERIOD COVERED:  0000Z (UTC) 08/12/96 - 0000Z (UTC) 08/13/96

Daily Status Report as of 226/0000Z

1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

   1.1 Competed Two sets of FOS/RD 6552 (Spectrophotometry of Inner =
Jovian Satellites)

       The Faint Object Spectrograph was used to make spectrographic =
observations of Jupiter's inner moon Thebe during its eastern elongation. =
Many things can be determined from the analysis of these spectra. The =
observations were executed as planned, and no problems were reported. 

   1.2 Completed GHRS/2 6541 (Interstellar Cadmium: Probing Galactic =
Chemical Evolution)

       The High Resolution Spectrograph (Side Two) was used to make spectr=
ographic observations of the O/B class star HD144217 in order to probe =
interstellar Cadmium and study the galactic chemical evolution. The =
observations were completed as planned, and no problems were reported.

   1.3 Completed WF/PC-2 6353 (A Snapshot Emission Line Imaging Survey of =
Very Low Excitation Planetary Nebulas)

       The WF/PC-2 was used to make snapshot observations as part to an =
emission line survey of the very low excitation planetary nebula =
PK327-02D1 (Class PNe). This target was selected based on the O III/H =
alpha line flux ratio. The observations were executed as scheduled, and =
no anomalies were noted.

   1.4 Completed FOS/BL 6498 (Accretion Streams in Magnetic Variables: =
FOS Eclipse of 4 Rosa)

       The Faint Object Spectrograph ( Blue side) was used to make Rapid =
Mode spectrographic observations of the accretion streams in the magnetic =
variable star (i.e., Cataclysmic variable) RXJ0515+01 (aka, 4 Rosa). This =
is a binary system, and it contains a white dwarf star, an accretion =
disk, a mass stream, and hot spot where the mass stream hits the disk and =
a companion star. The observations were completed as planned and no =
anomalies were reported.

   1.5 Completed Two Sets of WF/PC-2 6346 (Snapshot Survey of the =
Ultraluminous IRAS Galaxy Sample-Part 1 High)

       The WF/PC-2 was used to make snapshot survey observations of the =
ultraluminous IRAS galaxies QDOTULIR22 and IR16007+37. These data will be =
searched for multiple cores, which imply a merger has occurred, and for =
starburst regions. The observations were executed as scheduled, and no =
anomalies were noted.

   1.6 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 observati=
ons of the QSO/radio galaxy  3C395 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. 

   1.7 Completed FOS/BL/GHRS/2 5959 (Intergalactic Gunn-Peterson =
Absorption in Five Quasars)

       The Faint Object Spectrograph (Blue Side) was used to make =
moderate resolution, high signal to noise ratio, spectrographic =
observations of the quasar QSO-194025 in order to study its He II =
Gunn-Patterson absorption lines. The requested resolution will allow =
absorption due to the Lyman-Alpha forest to be separated from absorption =
due to the intergalactic medium. The observations were executed as =
scheduled, and no anomalies were noted.

2.0 FLIGHT OPERATIONS SUMMARY:

   2.1 Guide Star Acquisitions: 

                            Scheduled Acquisitions : 6
                                        Successful : 6

                          Scheduled Reacquisitions : 5
                                        Successful : 5

   2.2 FHST Updates: 

                              Scheduled : 16
                             Successful : 16

   2.3 Operations Notes: 

   A guide star loss-of-lock was encountered with FGS #1 with a torque =
star selector compensation error type B at 226/0514Z. During the FOS =
observation 14 a binary acquisition  guide star loss-of-lock occurred =
taking the TDF down until the occultation at 0556Z. (See Tomorrow's =
report for more details, Item 1.1)

   The NSSC-1 had a status buffer message at 226/0524Z due to no TDF at =
the start of the FOS observations #15. The Shutter did not open and the =
observation was lost. The FOS observation #16 was also conducted with the =
shutter closed. (See Tomorrow's report for more details, Item 1.1)

   The ESS took a power hit at 226/0025Z. All ESS systems were back on =
line by 226/0300Z.
