HUBBLE SPACE TELESCOPE

                       DAILY REPORT #2049

PERIOD COVERED:  0000Z (UTC) 01/28/98 - 0000Z (UTC) 01/29/98

Daily Status Report as of 029/0000Z

1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

   1.1 Completed NIC/3 7610 (NICMOS Plate Scale and Astrometric Calibration)

       The Near Infrared Camera (Camera Three) was used to make
observations of NGC-1850 (an open star cluster in Dorado) was used to
measure the plate scale, astrometric calibration, field rotation and field
distortion for the NICMOS camera.  The intercamera astrometric solution
will also be found.  The observations were executed as scheduled, and no
anomalies were noted.

   1.2 Completed Two Sets of NIC/1/3 7813 (NIC/3 HDF Darks)

       The Near Infrared Camera (Cameras One and Three) was used to make
internal dark calibration images which will be used when processing the
Hubble Deep Field images during the first NICMOS Camera Three campaign.
The observations were executed as scheduled, and no anomalies were noted.

   1.3 Completed NIC/1/2/3 7235 (Observations of the Hubble Deep Field)

       The Near Infrared Camera (Cameras One, Two, and Three) was used to
make observations of the Hubble Deep Field area HDF-123645.  This program
observes a portion of the Hubble Deep Field with all three NICMOS cameras
in the F160W and F110W filters to produce infrared images equivalent in
depth to the existing WF/PC-2 HDF images.  The observations were executed
as scheduled, and no anomalies were noted.

   1.4 Completed STIS/CCD 7918 (STIS CCD Pure Parallels for NIC/3 HDF Spec)

       The Space Telescope Imaging Spectrograph (CCD) was used to make pure
parallel, ultraviolet, slitless, spectrographic observations with the prime
Hubble Deep Field observations.  This proposal will run during the orbits
devoted to NICMOS HDF prime proposal 7235.  The observations were completed
as planned, and no problems were reported.

   1.5 Completed STIS/CCD 7900 (STIS CCD Pure Parallels for NIC/3 HDF)

       The Space Telescope Imaging Spectrograph (CCD) was used to make pure
parallel, ultraviolet, slitless, observations with the NIC/3 Camera.  This
proposal will run during the orbits devoted to NICMOS HDF prime proposal
7235.  The observations were completed as scheduled, and no anomalies were
reported.

   1.6 Completed NIC/3 7459 (The Age and Content of a {Proto}Galaxy Cluster
at z=2.39)

       The Near Infrared Camera (Camera Three) was used to make
observations of the proto-galaxy cluster Gal-Clust-1239.  Our WF/PC-2
observations of the field around the radio galaxy 53W002 {z=2.39} have
discovered a remarkable population of Lyman Alpha emission-line objects at
the same redshift, with 18 identified in a single WF/PC-2 mosaic.  The
observations were executed as scheduled, and no anomalies were noted.

2.0 FLIGHT OPERATIONS SUMMARY:

   2.1 Guide Star Acquisitions:

                            Scheduled Acquisitions : 6
                                        Successful : 6

       As reported in HSTAR 6330, the acquisition scheduled at 029/052159Z
defaulted to fine lock on FGS-2 only when FGS-1 lost lock.  Two proposals
which are described in tomorrow's report may have been affected: STIS 124
and NIC/3 7919.

                          Scheduled Reacquisitions : 9
                                        Successful : 9

   2.2 FHST Updates:

                              Scheduled : 14
                             Successful : 14

   2.3 Operations Notes:

       The NICMOS Hubble Deep Field proposals continue to be successfully
completed, although, as mentioned in 2.1 the single observation for NIC/3
7919 (Camera 3 Snapshots) may have been impacted.

       The NSSC-1 status buffer was dumped at 029/0651Z.

3.0 SIGNIFICANT FORTHCOMING EVENTS:

       Continuation of normal science observations and calibrations.
