HUBBLE SPACE TELESCOPE

DAILY REPORT #1475

PERIOD COVERED: 0000Z (UTC) 09/13/95 - 0000Z (UTC) 09/14/95

Daily Status Report as of 257/0000Z

1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

1.1 Completed Two Sets of GHRS/2 6172 (CRIMP2: Cycle 5 Condensed-Regimen
Integrated Monitoring Program)

The High Resolution Spectrograph (Side Two) was used to obtain darks,
internal flats (in photoscan mode), wavelength calibrations and observations
of standard star BD+28D4211. This includes detector calibration, sensitivity
monitoring, and wavelength monitoring. The observations were executed as
scheduled, and no anomalies were noted.

1.2 Completed Four sets of WF/PC-2 6219 (The Vertical Structure of the
Atmosphere of Neptune)

The WF/PC-2 was used to make multi-color image observations of the
planet Neptune at different longitudes in order to study the vertical
structure of its atmosphere. The data will be used to place constraints on
the composition and vertical structure of the clouds and haze above the main
cloud deck. The observations were completed as planned, and no anomalies
were reported.

1.3 Completed WF/PC-2 6119 (Snapshot Survey for Companions of Planetary
Nebula Nuclei)

The WF/PC-2 was used to make snapshot survey observations of planetary
nebula SP3 to study its nuclei and to look for possible companions. The
observations were executed as scheduled, and no anomalies were noted.

1.4 Completed Five Sets of GHRS/1 6171 (CRIMP1: Cycle 5 Condensed-Regimen
Integrated Monitoring Program)

The High Resolution Spectrograph (Side One) was used to obtain darks,
internal flats (in photoscan mode), wavelength calibrations and observations
of standard star BD+28D4211. This includes detector calibration, sensitivity
monitoring, and wavelength monitoring. The second and fourth iterations of
this proposal were terminated by the NSSC-1 during the internal flat
observations due to the excessive number of bad quality GHRS data reported in
telemetry. These events were recorded in HSTARs 5284 and 5287, respectively.
The remaining observations were executed as scheduled, and no further
anomalies were noted.

1.5 Completed GHRS/1 5870 (Dead or Sleeping Status of Magnetic Dynamos in
"Maunder Minimum")

The High Resolution Spectrograph (Side One) was used to make far
ultraviolet observations of solar type star HD29647. This star exhibits
weak, non-variable Ca II emission and a long rotation period. The
implication is that this star may have a weak magnetic field and undergoing a
"Maunder Minimum". The observations were executed as scheduled, and no
anomalies were noted.

1.6 Completed WF/PC-2 6095 (Hot Stellar Populations in Globular Cluster
Cores)

The WF/PC-2 was used to make observations of globular cluster NGC-6652
to study the radial gradients of the hot stellar population in its core
region. Observations were made in the blue, violet and far ultraviolet. The
FGS acquisition for this proposal failed due to the search radius limit being
exceeded. HSTAR 5285 was written.

1.7 Completed WF/PC-2 5760 (The Search for Super Planets Around Weak
T-Tauri Stars)

The WF/PC-2 was used to make I-Band observations of T-Tauri Class star
HBC388 in order to search for possible super planets by looking for thermal
radiation from the planets in orbit around this star. The observations were
completed as scheduled, and the only problem was reported in HSTAR 5286.
During the internal flat, the flat field lamp 1 current flagged high for one
telemetry sample.

1.8 Completed WF/PC-2 5353 (Low-Mass Binaries in the Hyades: Cycle 4 High)

The WF/PC-2 was used to make images of the low-mass, late M-Class
dwarf star RHY244 which is located in the Hyades cluster. Some of the
companion stars may be brown dwarfs. The observations were completed as
scheduled, and no problems were reported.

1.9 Completed WF/PC-2 5972 (Determination of the Extragalactic Distance
Scale)

The WF/PC-2 was used to make observations of the galaxy NGC-1365,
looking for standard candle Cepheid variable stars. The purpose of these
observations is to help estimate the Hubble constant with an accuracy of 10%.
The observations were executed as scheduled, and no anomalies were noted.
