HUBBLE SPACE TELESCOPE

DAILY REPORT #1571

PERIOD COVERED: 0000Z (UTC) 02/14/96 - 0000Z (UTC) 02/15/96

Daily Status Report as of 046/0000Z

1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

1.1 Completed FGS 5657 (Duplicity Among Hyades Stars: Cycle 4 High)

The FGSs (TRANS-Mode) were used to make astrometric observations of =
star VA529 located in the Hyades cluster in an attempt to find a close =
binary. After achieving fine lock, the acquisition lost lock at =
045/003352Z. HSTAR 5502 was written to document these events. The =
observations was completed as scheduled, and no further anomalies were =
noted.

1.2 Completed WF/PC-2 6253 (Pure Parallel Archive Program)

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 loss of lock mentioned for the previous proposal resulted in the loss =
of two WF/PC-2 observations while the take data flag was down. HSTAR 5502 =
described these events. Otherwise, the observations were completed as =
planned, and no other problems were reported.

1.3 Completed WF/PC-2 5907 (Colour Magnitude Diagrams of two =
Super-Metal-Rich Globular Clusters)

The WF/PC-2 was used to make observations of the super-metal-rich =
globular cluster NGC-224-G17. The high resolution of the PC will allow =
individual stars to be distinguished, from which the investigator can =
build a colour magnitude diagram of this unusual cluster. The =
observations were completed as scheduled, and no problems were reported.

1.4 Completed WF/PC-2 6235 (High Resolution Imaging of Radio Galaxies =
at Redshift Z~1.0)

The WF/PC-2 was used to make observations of faint radio galaxy =
3C239 which is known to have a redshift of about one. This is to attempt =
to determine the cause of the alignment of the blue-excess along the radio =
axis. The observations were executed as scheduled, and no anomalies were =
noted.

1.5 Completed WF/PC-2 5989 (Imaging of CL1358+62 and Its Environs: the =
Morphology-Density Relation))

The WF/PC-2 was used to make imaging observations of galactic =
cluster CL1358+62 (aka, Gal-Clus-1) in order to study the morphology of =
the galaxy as a function of its position in the cluster. The observations =
were executed as scheduled, and no anomalies were noted.

1.6 Completed GHRS/1/WF/PC-2 5865 (NLTE Analysis of the Hot Post-AGB =
Star ZNG1 in the Galactic Globular Cluster M-5)

Both the WF/PC-2 and the High Resolution Spectrograph (Side One) were =
used to make observations of the hot blue post AGB star NGC-5904-ZNG1 =
which is located in the globular cluster M-5. There are indications that =
there is a planetary nebula around this star. The observations were =
completed as scheduled, and no anomalies were noted.
