1) 

       The WF/PC-2 was used to make several internal bias, K-Spot, and flat
calibration observations to monitor the CCD camera electronics, the optical
alignment, and to check for contamination. The observations were completed as
planned, and no anomalies were noted. 

   1.10 Completed Three Sets of WF/PC-2 5493 (Synoptic Monitoring of Seasonal
Phenomena on Mars: Cycle 4 Medium)

       The WF/PC-2 was used to make observations of the planet Mars at
selected seasons, looking for periodic changes. The observations were
executed as scheduled, and no anomalies were noted. 
 
   1.11 Completed 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 PG1012+00 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. 

   1.12 Completed Two Sets of WF/PC-2 5343 (WFC Imaging of Nearby Bright
Quasars)

       The WF/PC-2 was used to make images of the bright quasar PKS1004+13
and PG1012+0 its host galaxy. The goal is to study the morphology of this
galaxy, and to see how it differs from non-QSO galaxies. They also will be
looking for the relationship between the properties of the host galaxy and
the luminosity of the quasar. The observations were completed as planned, and
no anomalies were reported.

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

       The WF/PC-2 was used to make images of galaxy NGC-3621 to be used in
measuring the periods of Cepheid variable stars within this galaxy. The
observations were completed as planned, and no anomalies were noted.

   1.14 Completed WF/PC-2 5450 (Host Galaxies and Cluster Environments of
Quasars)

       The WF/PC-2 was used to make observations of Quasar QSO-Q1222+1235 to
study the properties of its host galaxy and surrounding environment. The
observations were executed as scheduled, and no anomalies were noted. 

   1.15 Completed FOS/BL 5658 (White Dwarf Calibration)

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

   1.18 Completed Three Sets of WF/PC-2 5215 (The Martian Surface and
Atmosphere)

       The WF/PC-2 was used to make observations of Mars during its current
opposition to study its atmosphere and surface. The purpose is to place more
stringent constraints on the atmospheric water, ozone, airborne dust, surface
optical properties, and iron mineralogy. The observations were executed as

objects. HSTAR #5135 reported that FOS Observations #67 had a Mode Two target
acquisition failure at 057/1539Z. A NSSC-I Status Buffer Error Message was
received. No other anomalies were noted.
