observations of B class star HD121800. This star is in the line of sight of a
loop of gas in the halo of the Milky Way galaxy. A wavelength calibration
image was also taken. The observations were completed as scheduled, and no
anomalies were reported. 

   1.2 Completed WF/PC-2  5476 (Continuum Snapshots of 3CR Radio Galaxies) 

       The WF/PC-2 was used to make snapshot images of radio galaxy 3C220.1

   1.3 Completed Four Sets of FOS/BL 5444 (A UV Spectral Library of Metal-
Poor Massive Stars) 

       The FOS (Blue Side) was used for a snapshot program to obtain
ultraviolet spectra of AV396, NS191-67, NS85-67 and NS69-67, all metal-poor
stars in the LMC.  It will be useful for stellar atmosphere and stellar
evolution studies. FOS observations 102 and 103 were lost due to a guide star
acquisition failure at 028/1001Z. 

   1.4 Completed WF/PC-2 5408 (Star Cluster and CNO Abundance in Blue Compact
Galaxies)

       The WF/PC-2 was used to make observations of the star formation
regions within the low metallicity  blue compact galaxy SBS0335-05 to be used
to determine the size, color, and luminosity of imbedded star clusters. The
observations were executed as scheduled, and no anomalies  were noted.

   1.5 Completed Four Sets of WF/PC-2 5479 (Subarcsecond Structure in Nearby
AGNs)

       The WF/PC-2 was used to make snapshot observations of the nearby
active galactic nuclei of IC4329A, NGC-4990, IR1249-131 and MARK372 to study
the interactions between the central  engine, the stars, and the interstellar
matter in the AGN. The observations were executed as scheduled, and no
anomalies were noted.

   1.11 Completed FOS/BL 5314 (The Red Edge of the ZZ Ceti Instability Strip)

       The Faint Object Spectrograph (Blue Side) was used to make ultraviolet
observations of the variable white dwarf, ZZ Ceti class star WD0104-464 to
study its theoretical instability strip. The location of this strip is
uncertain. There was a binary target acquisition failure at 028/0338Z. The
data showed a maximum of only 13 counts in all diodes, with a peak of only
two counts per diode. HSTAR 5108 was written.

   1.12 Completed WF/PC-2 5746 (High Spatial Resolution Imaging and
Polarization of AGNs)

       The WF/PC-2 was used to make high resolution polarized images of the
AGN within MARK573 to provide information about the central source which is
hidden behind obscuring matter. The observations were completed as planned,
and no problems were reported.

   1.13 Completed WF/PC-2 5397 (Determination of the Extragalactic Distance
Scale: Cycle 4 High)
