The systems team performed a self- assessment of  the SDO priorities and
activities that need to be focused on as part of pre-PDR development
activities.  The weekly SDO systems meeting with the subsystems
focused on communicating these priorities, as well as discussing other
development areas of concern to the subsystem teams.   The review of
subsystem requirements and specifications continues to be a top priority,
with the entire team working to bring these documents under CM by PDR.
Subsystem-level PDRs are continuing, with the C&DH and GSE PDRs being
held this week.  The Contamination team held a multi-day working group
with both the spacecraft subsystems and visiting representatives from the
instrument teams, focusing on further identifying the SDO contamination
requirements and rationale for each, as well as discussing implementation
plans.  In addition, the I&T tiger team met multiple times as part on
the ongoing intensive effort to further define the I&T plan as part of
the development process prior to PDR.

For the Instruments, the quiet Holiday period was used to complete the
final revisions of the HMI Phase BCDE Statement of Work and CDRL list.
The final draft of the HMI Contract Performance Specification was also
completed.  e2v has completed modification of CCD test camera electronics
for the new 4k x 4k format and will begin functional checkout this week.
This test camera will be used in full image testing of first batch thin
and thick gate CCD devices after proper packaging of selected devices
in ceramic mounts.  Image characterization testing on cooled devices
will begin in two weeks.  The second run of the thin gate batch is in
process and proceeding well which will be completed by end of month -
e2v expects higher device yields.  RAL continued detailed design work
on CCD camera electronics and continued operational checkout of the
camera electronics EGSE.  Stanford University has established a letter
authorization for cost with PRAXIS (e2v proxy) to cover the balance of
the e2v CCD development work handed over from NRL.  The PRAXIS contract
will be finalized after receipt and evaluation of the e2v proposal (due
this week).  LMSAL has requested proposals from e2v & RAL for the flight
phase contracts.  The e2v proposal for the flight phase has been received
and the RAL proposal for the flight camera electronics is due mid-January.

The HMI team is preparing for the joint HMI/AIA interface working group
to be held in Palo Alto on January 12 through January 15th.  Peer reviews
on February 4, 2004 will cover the HMI oven structure, HMI electronics box
enclosure, and optical mount alignment method.  Two new members have been
added to the HMI team, John Miles and Carin Lundquist.  John will phase
in as the HMI Systems Engineer, and Carin is joining the HMI thermal team.

The AIA team continues to prepare for our initial I/F working group
next week where critical accommodation requirements will be worked.
LMSAL supported the SDO Contamination TIM at GSFC and delivered a
preliminary Contamination Control Plan, along with a justification for
their data rate increase (58 to 67Mbps) and resource impact statement
for increasing the quantity of Guide Telescopes from 2 to 4.  LMSAL was
given approval for initiating some critical long lead item procurements.

The ground system team had TSI demonstrate their high data rate
receiver unit with the Viterbi decoder's function integrated inside
the box.  The unit worked fine in the loop-back mode using their own
modulator.  However, the receiver had some RF lock up difficulties.
Another demonstration is scheduled for Friday, January 9.  The team
also continues working on the design concepts and materials for their
peer reviews.  The Review Panels for both the Operations and MOC peer
reviews have been selected and confirmed.  The Operations and MOC peer
reviews are scheduled for February 5, and February 11, respectively.

Congratulations to Mike Garner, SDO's Software Quality Assurance Engineer,
who successfully passed an exam to become a certified American Society
Software Quality Engineer.  Successful completion of this comprehensive
exam nationally certifies his skills and credentials in SWQA.  Mike is
also nearing completion of the SWQA plan which is based on the IEEE
Standard 730.  Rich Marriott has been brought on board as the Project's
new Materials Assurance Engineer.  Rich is focusing on completion of
the revised materials & Process Implementation plan for release by the
Mission PDR.  I also welcome Noman Siddiqi (Parts engineer) who will
be assisting Dennis Krus in making sure subsystem parts lists are up to
date and breadboard, ETU, & Flight parts are ordered/delivered in time to
support each box schedule.  Noman will also maintain the parts database.

The CM team is getting organized for the many upcoming CCBs
(Monday mornings thru February) and entering documentation into
SDO's intranet database.  In addition, they have been inputting the
released Mission Requirements Document (MRD) into DOORS (requirements
traceability software system) and will soon be entering other released
requirements/specifications and working with the systems team on linking
the documents.  In the area of Project Support, the team continues the
coordination of items needed for the installation of the new offices in
Building 29, such as removal of current electrical/phone/LAN lines and
getting the current occupants of the cubicles moved.


Thanks, Ken
