PERIOD COVERED:  0000Z (UTC) 06/29/98 - 0000Z (UTC) 06/30/98

Daily Status Report as of 181/0000Z

1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:

   1.1 Completed NIC/2 7834 (A Search for Giant Planets Around Very Young
Nearby Late-type Dwarfs)

       The Near Infrared Camera (Camera Two) was used to make observations
of the very young, late-type, dwarf star HD48189 as part of a search for
large planets.  Very young late-type dwarfs at distances closer than 30 pc
are excellent sites to provide a direct detection of extrasolar planets.
The observations were executed as scheduled, and no anomalies were noted.

   1.2 Completed Eight Sets of STIS/CCD 7908 (POMS Test Proposal: STIS
Non-Scripted Parallel Proposal)

       The Space Telescope Imaging Spectrograph (CCD) was used to make
calibration observations as part of the POMS Test Proposal.  This was a
STIS non-scripted parallel proposal.  The observations were completed as
planned, and no problems were reported.

   1.3 Completed Three Sets of WF/PC-2 7909 (POMS Test Proposal: WF II
Parallel Archive Proposal)

       The WF/PC-2 was used to make parallel observations as part of the
POMS test proposal.  This test proposal is designed to simulate scientific
plans.  The observations were completed as planned, and no problems were
reported.

   1.4 Completed WF/PC-2 7431 (Snapshot Survey of Microlensed Source Stars)

       The WF/PC-2 was used to make snapshot survey images of microlensed
source star MACHO-95-1.  Gravitational microlensing surveys have revealed
an excess of lensing events over theoretical predictions toward both the
Large Magellanic Cloud and the Galactic Bulge.  The observations were
completed as planned, and no anomalies were reported.

   1.5 Completed WF/PC-2 7434 (The Supernova Intensive Study)

       TheWF/PC-2 was used to continue the long-term project on supernovae
by observing SN1996X.  HST can make unique contributions to understanding
supernovae, as has been demonstrated through this program in past years.
The aim of the proposal is to explore the UV emission from supernovae,
exploit the spatial resolution of HST and press the late-time observations
of supernovae into uncharted territory.  The observations were completed as
planned, and no anomalies were reported.

   1.6 Completed Six Sets of NIC/2/3 7907 (NICMOS Pure Parallel Winter 97-98)

       The Near Infrared Camera (Cameras Two and Three) was used to make
pure parallel spectrographic observations of sky regions when another
instrument is prime.  The observations were completed as planned, and no
anomalies were reported.

   1.7 Completed Two Sets of STIS/CCD 7910 (STIS Extragalactic Parallel Survey)

       The Space Telescope Imaging Spectrograph (CCD) was used to make
extragalactic slitless spectrographic observations as part of the parallel
high galactic latitude survey to search for emission line galaxies.  Data
was taken in parallel, and not subject to proprietary time.  The
observations were executed as scheduled, and no anomalies were noted.

   1.8 Completed Three Sets of WF/PC-2 7712 (WF/PC-2 Cycle 7 Supplemental
Darks pt2/3)

       The WF/PC-2 was used to make a series of Cycle 7 supplemental
calibration darks.  This dark calibration program obtains three dark frames
every day to provide data for monitoring and characterizing the evolution
of hot pixels.  The observations were executed as scheduled, and no
anomalies were noted.

   1.9 Completed NIC/1/2/3 7226 (Search for Massive Jupiters)

       The Near Infrared Camera (Cameras One, Two and Three) was used to
make a corographic search for massive planets around the nearby, young main
sequence star HR7329.  Because of the extreme youth of this object, any
low-mass brown dwarf and planetary companions will still be in a higher
luminosity phase and thus easily detectable.  A dark calibration image was
also taken.  The observations were executed as scheduled, and no anomalies
were noted.

   1.10 Completed Two Sets of STIS/CCD 7948 (CCD Dark and Bias Monitor --
Cont. to Dec. 98)

       The Space Telescope Imaging Spectrograph (CCD) was used to measure
CCD dark current and bias rates for the 2 supported amplifier settings
{GAIN=1 and GAIN=4} in order to gather data for making superdarks and
superbiases. The data will be used to track the growth of hot pixels on the
CCD in general and within the various target acquisition apertures
specifically.  The observations were executed as scheduled, and no
anomalies were noted.

   1.11 Completed NIC/1/2 7690 (NICMOS Pointed Super Flats)

       The Near Infrared Camera (Cameras One and Two) was used to make
super flat field calibration observations.  The observations will be used
to build high signal/noise ratio NICMOS flat fields for the different
filters.  The observations were executed as scheduled, and no anomalies
were noted.

   1.12 Completed WF/PC-2 7618 (WF/PC-2 Cycle 7 Photometric Monitor UV/OPT STD)

       The WF/PC-2 was used to make observations of the standard star
GRW+70D582 as part of a Cycle 7 photometric monitoring program.  This
ultraviolet spectrophotometric standard star was observed in a variety of
filters and cameras to monitor the photometric stability and quantum
efficiency of WF/PC-2 from the far-ultraviolet to near-infrared.  The
observations were completed as scheduled, and no problems were reported.

   1.13 Completed WF/PC-2 7588 (Measuring Q0 With Type IA Supernovae)

       The WF/PC-2 was used to make observations of supernova SN1997A4 in
order to measure the Q0 parameter.  This is in order to producing a precise
Hubble diagram from which can be used to measure the cosmic deceleration
and global curvature of the universe.  HST can make an essential
contribution by providing photometry with substantially higher precision
and better temporal coverage than can be obtained from the ground.  The
observations were executed as scheduled, and no anomalies were noted.

   1.14 Completed WF/PC-2 7501 (Expansion Parallax Distances to Planetary
Nebulae)

       The WF/PC-2 was used to make parallax distance measurements of the
planetary nebula NGC-6886.  The largest impediment to our understanding of
planetary nebulae is the lack of reliable distances.  Acquired by
generalized statistical methods in all but a handful of cases, individual
PNe distances are often uncertain by factors of two or more.  The
observations were executed as scheduled, and no anomalies were noted.

   1.15 Completed NIC/2 7227 (A Search for Low Mass/Sub-Luminous Companions
to M-Stars)

       The Near Infrared Camera (Camera Two) was used to make a search for
low mass/sub-luminous companions to low mass M class stars.  Knowledge of
stellar and sub-stellar masses and luminosities at and below the ~0.08
M{sun} H-burning limit is of fundamental importance.  A dark calibration
image was also taken.  The observations were completed as planned, and no
problems were reported.

   1.16 Completed NIC/1/2/3 7216 (Near-Infrared Observations of NGC-6611
{M-16})

       The Near Infrared Camera (Cameras One, Two and Three) was used to
make observations of the nebula NGC-6611 (a.k.a., M-16).  The NICMOS should
be able to extend the IMF statistics well into the subsolar-mass range and
examine many of the EGGs {i.e., Evaporating Gas Globules} seen in WF/PC-2
images.  The observations were completed as planned, and no problems were
reported.

   1.17 Completed Four 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.

   1.18 Completed FOC/96 7685 (FOC F/96 UV Throughput Monitoring)

       The Faint Object Camera (f/96) was used to make observations of
standard star BPM16274 in order to perform ultraviolet throughput
monitoring.  These observations are taken four time during the cycle.  An
internal calibration flat image was also taken.  The observations were
completed as scheduled, and no problems were reported.

   1.19 Completed NIC/1 7867 (NICMOS Imaging of the Dusty CfA Seyfert Nuclei)

       The Near Infrared Camera (Camera One) was used to make observations
of the Seyfert Galaxy NGC-5674.  These data will allow us to determine if
the Seyfert Type 1/2 dichotomy is best explained by the unified model, the
evolutionary picture, or a combination of both of these scenarios.  The
observations were executed as scheduled, and no anomalies were reported.

   1.20 Completed NIC/1/2/3 7820 (The Metallicity Distribution of the
Globular Cluster Systems of Giant Elliptical Galaxies)

       The Near Infrared Camera (Cameras One, Two and Three) was used to
study the metallicity distribution in the globular clusters contained in
the large elliptical galaxy NGC-3311.  This is an ideal use of infrared
data to significantly augment existing optical data.  The observations were
completed as scheduled, and no anomalies were reported.
