Daily Status Report as of 010/0000Z

1.0 OBSERVATIONS SCHEDULED AND ACCOMPLISHED:

    1.1 Completed WF/PC-2 9238 (The Spatial and Ionization Structure of Cas 
A's Metal-Rich Ejecta)

        The WF/PC-2 was used to survey the small-scale spatial and 
ionization structures in the metal-rich ejecta of Cassiopeia A {Cas A}, 
then use these results to test reverse shock and CSM-interaction 
hydrodynamic and line emission models.  Cas A is the prototype for the 
class of young, oxygen-rich SNRs containing material moving at several 
thousand km s^-1 and exhibiting extreme O and Si-group {Si, S, Ar, and Ca} 
abundances due to nuclear processing in a massive star.  All observations 
completed nominally.

    1.2 Completed Two Sets of WF/PC-2 8937 (Cycle 9 Supplemental Darks pt2/3)

        The WF/PC-2 was used obtain three dark frames every day to provide 
data for monitoring and characterizing the evolution of hot pixels.  No 
problems were encountered.

    1.3 Completed Two Sets of STIS/CCD 8906 (Hot Pixel Annealing)

        The Space Telescope Imaging Spectrograph (CCD) was used to measure 
the effectiveness of the CCD hot pixel annealing process by measuring the 
dark current behavior before and after annealing and by searching for any 
window contamination effects.  In addition, CTE performance is examined by 
looking for traps in a low signal level flat.  There were no reported problems.

    1.4 Completed WF/PC-2 8222 (An Emission Line Survey of the Crab Nebula)

        The WF/PC-2 was used to conduct an emission line survey of the Crab 
Nebula (a.k.a., M-1) in the light of emission from O I, S II, and O III, 
and in a single continuum band.  In addition to our specific scientific 
objectives, this survey will provide a data set that is essential to all 
future studies of the structure, dynamics, and evolution of the Crab.  The 
observations were executed as scheduled, and no anomalies were reported.

    1.5 Completed 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 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

    1.7 Completed Two Sets of STIS/MA1/MA2 8920 (Cycle 10 MAMA Dark 
Measurements)

        The Space Telescope Imaging Spectrograph (MA1 and MA2) was used to 
perform the routine monitoring of the MAMA detector dark noise, and is the 
primary means of checking on health of the MAMA detectors systems through 
frequent monitoring of the background count rate.  The proposal completed 
with no reported anomalous activity.

    1.8 Completed Two 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.

    1.9 Completed STIS/CCD 9107 (The Fundamental Plane for Nuclear Black Holes)

        The Space Telescope Imaging Spectrograph (CCD) was used to conduct 
more in-depth searches for supermassive black holes in galaxy 
centers.  Previous work has led to the discoveries that {1} most or all hot 
galaxies contain massive dark objects at their centers, presumably black 
holes; {2} there is a remarkably tight correlation between the black-hole 
mass and the luminosity-weighted velocity dispersion of the hot component 
of the galaxy. This mbh-Sigma relation has a scatter which is <0.3 dex in 
mbh and consistent with zero.  This relationship suggests a strong link 
between black-hole formation, AGN activity, and galaxy formation, and once 
it is understood this link should advance our understanding of all three 
processes.  The goal of this proposal is to investigate the scatter in the 
mbh-Sigma relation and the role of possible second parameters, by examining 
a sample of galaxies at fixed velocity dispersion Sigma=200+/- 20 
kms.  This approach decouples the effects of a second parameter from 
uncertainties in the shape of the mbh-Sigma relation, and minimizes 
spurious correlations because all of the galaxies will be studied using the 
same well-tested observational and modeling techniques.  No anomalous 
activity occurred.

    1.10 Completed Two Sets of WF/PC-2 9318 (POMS Test Proposal: WFII 
Parallel Archive Proposal Continuation)

        The WF/PC-2 was used to perform the generic target version of the 
WFPC2 Archival Pure Parallel program.  The program was used to take 
parallel images of random areas of the sky, following the recommendations 
of the Parallels Working Group.  As described in 2.1 and HSTAR 8461, the 
acquisition for the second iteration of this proposal defaulted to fine 
lock backup on one FGS only, possibly affecting fourteen 
observations.  Otherwise, there were no further reported problems.

    1.11 Completed STIS/CCD 8669 (Merger-Driven Evolution Of Galactic 
Nuclei: Observations Of The Toomre Sequence)

        The Space Telescope Imaging Spectrograph (CCD) was used to observe 
galaxy mergers that are believed responsible for triggering starburst and 
AGN activity in galaxies, and even perhaps transforming spiral galaxies 
into ellipticals.  As described in 2.1 and HSTAR 8461, the acquisition for 
this proposal defaulted to fine lock backup on one FGS only, possibly 
affecting three observations.  Otherwise, the proposal completed nominally.

2.0 FLIGHT OPERATIONS SUMMARY:

    2.1 Guide Star Acquisitions:
       Scheduled Acquisitions:  4
    Successful:  4

        Per HSTAR 8461, the acquisition at 009/215944Z defaulted to fine 
lock backup on FGS-3 only when the scan step limit was exceeded on 
FGS-2  The following re-acquisition at 009/232854Z was affected as 
well.  The proposals detailed in  may have been impacted.
  Scheduled Re-acquisitions: 10
    Successful: 10

    2.2 FHST Updates:
    Scheduled: 12
    Successful: 12

    2.3 Operations Notes:

        Using ROP SR-4A, an SSR engineering record session was commanded at 
009/1921Z.

        The 486 engineering status buffer was dumped and cleared at 
009/2315Z as directed by ROP Df-18A.

3.0 SIGNIFICANT FORTHCOMING EVENTS:

        A NSSC-1 flight software (FSW) 7.5.3 patch installation is 
scheduled for approximately 010/1630Z today.  Neither the NSSC-1 
application processors for the NCS nor the COSTAR will be active during the 
uplink.

        Continuation of normal science observations and calibrations.
