Protostar Jet)

       The Faint Object Spectrograph (Red Side) was used to make =
observations of Herbig-Haro object HH47.  The main purpose is to obtain =
spectra of the jet in protostar HH47 to investigate the mass exchange =
between the stream and the surrounding medium and to look for differences =
between Mach disk emissions and bow shock emissions.  A wavelength =
calibration image was also taken.  A wave length calibration image was =
also taken.  The observations were executed as scheduled, and no =
anomalies were reported.

       The WF/PC-2 was used to execute a pure parallel program taking =
ultraviolet observations running concurrently with prime science =
observations.  The intent is to search for extra-galactic sources with =
flux excesses at 3000 A0 and galactic sources with excesses at 1600 A0.  =
The observations were completed as planned, and no problems were =
reported.

   1.4 Completed WF/PC-2 5849 (Host Galaxies of Luminous Nearby Quasars)

superflats.  The observations were completed as planned, and no problems =
were reported.

Lacertae Objects)

       The WF/PC-2 was used to make short and deep observations of the BL =
Lacertae class object OJ287.  The short exposures will allow study of the =
inner regions of the host galaxy.  The longer exposures will allow a =
search for faint galaxy companions and any interaction between the faint =
companion and the AGN.  The observations were executed as scheduled, and =
no anomalies were noted.

   1.19 Completed FOC/96 6645 (UV-Optical spectra of Middle Age Pulsars: =
Thermal VS. Non-Thermal)

       The Faint Object Camera (f/96) was used to make both ultraviolet =
and optical deep observations of the middle aged isolated pulsar =
PSR-B0656.  From earlier HST/FOC images of this object, it was determined =
that most of the flux is non-thermal.  The purpose of these deep images =
is to measure the flux in several bandpasses.  The observations were =
completed as planned, and no anomalies were reported.

Companions to nearby M Dwarf)

       The FGSs were used in both the POS and TRANS Modes to make =
astrometric observations of low mass companions to M class dwarf star =
