1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

   1.1 Completed Three Sets of 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.

   1.2 Completed Two Sets of STIS/MA1/MA2 7921 (STIS MAMA Pure Parallels
for NIC/3 HDF - Spec)

       The Space Telescope Imaging Spectrograph (MA1 and MA2) was used to
make pure parallel, ultraviolet observations to be used in the NIC/3 HDF
campaign.  The MAMA images will be used to search for Lyman-break galaxies
at z>2.0, and z>1.0.  The observations were executed as scheduled, and no
anomalies were noted.

   1.3 Completed STIS/CCD 7636 (STIS Spectroscopic CCD Flatfielding)

       The Space Telescope Imaging Spectroscope (CCD) was used to make a
CCD flat field calibration observation in the spectrographic mode.  A bias
calibration was also taken.  The observations were completed as planned,
and no anomalies were reported.

   1.4 Completed Two Sets of WF/PC-2 7620 (WF/PC-2 Cycle 7 Standard Darks)

       The WF/PC-2 was used to make a series of Cycle 7 standard dark
calibration images.  This dark calibration program obtains dark frames
every week in order to provide data for the ongoing calibration of the CCD
dark current rate, and to monitor and characterize the evolution of hot
pixels.  The observations were executed as scheduled, and no anomalies were
noted.

   1.5 Completed NIC/3 7815 (NICMOS Earth Flats)

       The Near Infrared Camera (Camera Three) was used to make a Earth
flat field calibration image.  This proposal obtains a series of earth
flats for a subset of narrow and medium band NIC/3 filters in advance of
the NIC/3 campaign.  These flats will be used to generate the master flats
for narrow-band filters and to determine the OTA illumination pattern as a
function of wavelength.  The observations were completed as planned, and no
anomalies were reported.

   1.6 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.

   1.7 Completed Two Sets of NIC/1/2/3 7456 (Water in Protoplanetary Disks)

       The Near Infrared Camera (Cameras One, Two and Three) was used to
make observations of the protoplanetary disk around stars and LKCA-4 and
BP-Tau to search for water in their disks.  This survey will be the first
to take a detailed look at the gas phase properties of pre-main-sequence
disks at AU distances.  The observations were completed as scheduled, and
no anomalies were reported.

   1.8 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.

   1.9 Completed Three Sets of 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.

   1.10 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.

   1.11 Completed Ten Sets of STIS/MA2 7604 (Cycle 7 MAMA Dark Measurements)

       The Space Telescope Imaging Spectrograph (MA2) was used to make MAMA
dark measurements.  These darks will be used in later image reductions and
also trended over the instrument's life time as an indicator of the
detector's degradation or damage.  The observations were completed as
scheduled, and no problems were reported.
