HUBBLE SPACE TELESCOPE

DAILY REPORT       # 3362

PERIOD COVERED: DOY 133

Part 3 of 3

STIS 9688

Connecting the X-Ray and UV Ionized Absorbers in MRK 279

We propose a deep X-ray/UV spectroscopy campaign on the bright
Seyfert 1 galaxy MRK 279, using Chandra LETGS, HST/STIS, and FUSE.
Our main scientific goal is to study the AGN outflow seen as an
ionized absorber in this galaxy, focusing on the crucial connection
between the X-ray and UV manifestations of the outflows. We will map
the ionization and velocity structure, measure the elemental
abundances and then determine the mass and kinetic luminosity flux of
the outflow- all stepping stones for studying the importance of
outflows in the evolution of AGN and their host galaxies. In addition
we will use the LETGS data to determine the existence of relativistic
CNO emission lines in the spectrum. 

NICMOS 9702

NICMOS Parallel Thermal Background

NICMOS Camera 2 pure parallel exposures in the F222M and F237M
filters to establish the stability of the HST+NCS+Instrument thermal
emission. This data will be compared against the already available
Camera 3 measurements in F222M which show an increased thermal
background. 

STIS 9708

STIS Pure Parallel Imaging Program: Cycle 11

This is the default archival pure parallel program for STIS during
cycle 11. 

WFPC2 9709

POMS Test Proposal: WFII parallel archive proposal

This is the generic target version of the WFPC2 Archival Pure
Parallel program. The program will be used to take parallel images of
random areas of the sky, following the recommendations of the 2002
Parallels Working Group. 

WFPC2 9710

POMS Test Proposal: WFII backup parallel archive proposal

This is a POMS test proposal designed to simulate scientific plans.

FLIGHT OPERATIONS SUMMARY:

Significant Spacecraft Anomalies: (The following are preliminary
reports of potential non-nominal performance that will be
investigated.) 

HSTAR 9033:  Solar Array Section 3 anomaly re-occurrence.  Through 
             examination of EPS daily plots, a temporary
             re-occurrence of the SA Section 3 (-E SPA) anomaly from
             Day 036 where part of a SA "circuit" shorted to
             structure ground.  The Day 126 event occurred while in
             trickle-charge and was sustained for approximately 18
             seconds.  As with the Day 036 event (HSTAR 8923),
             structure current was present with a peak of 1.6 Amps as
             was the indicated increase in Section 3 current reading.
             Following the 18 second event, the structure current and
             SA Section 3 current returned to normal. Under
             investigation.
