PERIOD COVERED:  0000Z (UTC) 03/07/95 - 0000Z (UTC) 03/08/95

Daily Status Report as of 067/0000Z

1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:


   1.1 Completed GHRS/1 5413 (The Local ISM Flow Within the Heliosphere) 

        The High Resolution Spectrograph was used to make observations to
study the flow of neutral atoms in the interstellar medium by observing
diffuse sky background in Lyman Alpha. A wavelength calibration image was
also taken. Observations # 16, 18, and 19 were missing from a dump which was
downloaded at 066/1200z (HSTAR #5150). The OSS reported that observation #15
ran long and an HRS-9 status buffer error message was received at 066/0357Z
due to a carrousel out-of lock delay on observation #16. Observation #18 and
19 were lost due to a carrousel reset onboard delay.

   1.2 Completed GHRS/1 5595 (GHRS ECH-A Wavelength Monitor: Cycle 4) 

       The High Resolution Spectrograph was used to make wavelength spectral
lamp calibration observations to measure the instrumental characteristics of
the Echelle-A spectrograph. The observations were completed as planned, and
no problems were reported. 

   1.3 Completed WF/PC-2 5560 (WF/PC-2 Cycle 4 Calibration: Internal Monitor.
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. 

   1.4 Completed WF/PC-2 5343 (WFC Imaging of Nearby Bright Quasars)

       The WF/PC-2 was used to make images of the bright quasar PG1402+261
and 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.

   1.5 Completed WF/PC-2 6140 (WF/PC-2 Cycle 4 Calibration: Ramp filters,
Internal Calibration)

       The WF/PC-2 was used to make visual flat calibration images as part of
a ramp filter calibration test. The observations were completed as planned
and no problems were reported.

   1.6 Completed WF/PC-2 5629 (WF/PC-2 Cycle 4 Photometric Calibration
Monitor 1C: 4-Chip STD in F170W)

       The WF/PC-2 was used to make photometric calibration observations of
the ultraviolet standard star GRW+70D582. The observations were executed as
scheduled, and no anomalies were noted. 

   1.7 Completed WF/PC-2 6143 (WF/PC-2 Cycle 4 Photometric Calibration:
Smaller Set, Part II)

       The WF/PC-2 was used to make single CCD calibration observations of
standard star  GRW+70D582 to monitor the photometric stability and quantum
efficiency of the PC1 and WF3. The observations were executed as scheduled,
and no anomalies were reported.

   1.8 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 MARK699 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. 

   1.9 Completed FOS/BL 5581 (Pulsating White Dwarf DN Draconis)

       The FOS (Blue Side) was used in the rapid mode to cover the 17.1 hour 
beat period of the pulsating DA white dwarf DN Draconis (aka G226-29) to 
determine the index of the pulsational mode which will allow for the outer
hydrogen layer to be determined.  The observations completed nominally with
no reported problems.
