PERIOD COVERED:  0000Z (UTC) 11/15/01 - 0000Z (UTC) 11/16/01

Daily Status Report as of 320/0000Z

1.0 OBSERVATIONS SCHEDULED AND ACCOMPLISHED:

    1.1 Completed Six Sets of WF/PC-2 9042 (An Archive To Detect The 
Progenitors Of Massive, Core-Collapse Supernovae)

         The WF/PC-2 was used to search for supernovae which have massive 
star progenitors.  The already extensive HST archive and high-resolution 
ground-based images of galaxies within ~20 Mpc enables us to resolve and 
quantify their individual bright stellar content.  As massive, evolved 
stars are the most luminous single objects in a galaxy, the progenitors of 
core-collapse supernovae should be directly detectable on pre-explosion 
images.  One Type II progenitor has been observed this year, and the 
investigators have proposed a short, companion WFPC2 proposal to confirm 
this candidate and identify a second.  The observations completed nominally.

    1.2 Completed Five Sets of STIS/CCD 9285 (POMS Test Proposal: STIS 
Non-scripted Parallel Proposal Continuation III)

        The Space Telescope Imaging Spectrograph (CCD) was used to make low 
galactic latitude, non-scripted parallel observations as part of a POMS 
test proposal.  The observations were completed as planned, and no 
anomalies were reported.

    1.3 Completed Three Sets of WF/PC-2 8936 (Cycle 10 Supplemental Darks 
Pt1/3)

        The WF/PC-2 was used to perform a dark calibration program that 
obtains three dark frames every day to provide data for monitoring and 
characterizing the evolution of hot pixels.  The proposal completed with no 
reported problems.

    1.4 Completed Three Sets of STIS/CCD 9066 (Closing in on the Hydrogen 
Reionization Edge of the Universe)

        The Space Telescope Imaging Spectrograph (CCD) was used in parallel 
constrain the Hydrogen reionization edge in emission that marks the 
transition from a neutral to a fully ionized IGM at a predicted 
redshifts.  The proposal completed uneventfully.

    1.5 Completed Four Sets of STIS/CCD 8901 (Dark Monitor-Part 1)

        The Space Telescope Imaging Spectrograph (CCD) was used to monitor 
the darks.  There was no anomalous activity.

    1.6 Completed FGS/1 9034 (The Masses and Luminosities of Population II 
Stars)

        Fine Guidance Sensor #1 was used to observe the mass-luminosity 
relation {MLR} of Population II stars of which very little is currently 
known.  With the advent of the Hipparcos Catalogue, improved distances to 
many spectroscopic binaries known to be Pop II systems are now 
available.  After surveying the literature and making reasonable estimates 
of the secondary masses, we find 13 systems whose minimum separation should 
be larger than the resolution limit of FGS #1.  The observations completed 
nominally.

    1.7 Completed Six Sets of WF/PC-2 9244 (POMS Test Proposal: WFII 
Parallel Archive Proposal Continuation)

        The WF/PC-2 was used to perform a generic target version of the 
Archival Pure Parallel program.  The program will be used to take parallel 
images of random areas of the sky, following the recommendations of the 
Parallels Working Group.  The observations completed with no anomalous 
activity.

    1.8 Completed Two Sets of WF/PC-2 9250 (Hubble Heritage Observations of 
NGC 1275)

        The WF/PC-2 was used to observe the active galaxy NGC 1275 for a 
Hubble Heritage release.  It is planned to obtain a two-orbit I-band image 
that will be combined with archival B and R-band images of the same object, 
to result in a 3-color image.  There were no reported problems.

    1.9 Completed STIS/CCD 8903 (Bias Monitor - Part 1)

        The Space Telescope Imaging Spectrograph (CCD) was used to monitor 
the bias in the 1x1, 1x2, 2x1, and 2x2 bin settings at gain=1, and 1x1 at 
gain = 4 to build up high-S/N superbiases and track the evolution of hot 
columns.  There were no problems.

    1.10 Completed STIS/CCD 9055 (Direct Detection of an Extrasolar Planet 
in Reflected Light)

        The Space Telescope Imaging Spectrograph (CCD) was used to observe 
HD 209458B that is the first extrasolar planet known to transit the disk of 
its parent star.  It is proposed to detect directly the gas giant planet 
orbiting HD 209458 in reflected light by observing the secondary eclipse, 
i.e. when the planet is occulted by the star.  There were no reported 
anomalies.

    1.11 Completed Four Sets of WF/PC-2 8941 (Cycle 10 UV Earthflats)

        The WF/PC-2 was used to monitor flat field stability by obtaining 
sequences of earth streak flats to improve the quality of pipeline flat 
fields for the WFPC2 UV filter set.  The proposal had no problems.

    1.12 Completed Three Sets of STIS/CCD 8910 (Sparse Field CTE 
Test-Internal {Cycle 10})

        The Space Telescope Imaging Spectrograph (CCD) was used to perform 
CTE measurements that are made using the "sparse field test", along both 
the serial and parallel axes.  This program needs special commanding to 
provide {a} off-center MSM positionings of some slits, and {b} the ability 
to read out with any amplifier {A, B, C, or D}.  No problems were encountered.

    1.13 Completed Five Sets of WF/PC-2 8942 (Cycle 10 Intflat Sweeps and 
Linearity Test)

        The WF/PC-2 was used to monitor the pixel-to-pixel flatfield 
response and provide a linearity check.  These intflat sequences are done 
once during the year and the images will provide a backup database in the 
event of complete failure of the visflat lamp as well as allow monitoring 
of the gain ratios.  There were no reported problems.

2.0 FLIGHT OPERATIONS SUMMARY:

    2.1 Guide Star Acquisitions:
       Scheduled Acquisitions:  9
Successful:  9

        Per HSTAR 8400, the acquisition at 320/000253Z defaulted to fine 
lock backup on FGS-3 only when the scan step limit was exceeded on 
FGS-2.  Three proposals, each occurring during the period of the next 
report, may have been affected: WF/PC-2 9042, STIS 9285 and WF/PC-2 8936.
  Scheduled Re-acquisitions:  4
Successful:  4

    2.2 FHST Updates:
Scheduled: 23
Successful: 23

    2.3 Operations Notes:

        Using ROP SR-1A, the SSR EDAC error counter was cleared twice.

        Operations personnel participated in GSFC Internal Simulation #12 
(Deploy).

        The telemetry mnemonic ND1DRET1 flagged out-of-limits low at 
319/211343Z with a value of  -0.02030991.  The parameter returned within 
bounds at 319/213213Z.  HSTAR 8399 was written.

        A TTR was written for a required re-transmit during a NSSC-1 load 
at 320/042540Z.  SI C&DH errors were then reset at 320/0430Z per ROP NS-5.

        Another TTR was generated when there was a re-transmit during a 486 
load at 320/090823Z.  Accordingly, using ROP DF-i8A, an engineering status 
buffer limit was adjusted at 320/0912Z.

3.0 SIGNIFICANT FORTHCOMING EVENTS:

        Continuation of normal science observations and calibrations.
