9. Future science First solar cycle will be completed in 2006 –What are flow characteristics of ascending vs descending phase? Space weather –Develop quick look flow maps & helicity activity indicators –Calibrate far side signal, search for activity thresholds ESA Solar Orbiter participation –Combine local helio products with high-latitude data –Probe flows under the poles –Irene González-Hernández lead SDO/HMI Co-Is –Install rings and inversion pipelines with community HELAS participation –European Network in Helio- and Asteroseismology

10. Modulator upgrade New driver circuit –Original driver has asymmetric switching time in and out of a retardation state –New driver has equal switching time –Improves magnetogram zero-point by factor of 30, down to 0.1 G New modulators –Thermally stabilized –Excellent optical quality Deployment –Scheduled for Feb-Mar 2006 –In time for April 2006 STEREO Launch

11. Sometimes it gets better when you stare at it… George Luis, Tim Purdy, Mike Soukup, Jack Harvey

12. Magnetograms Mauna Loa 200511110200 Jack Harvey, Gordon Petrie, Richard Clark, Cliff Toner, Harry Jones Original modulator & circuitNew modulator & circuit

13. New shelters & instrument Learmonth shelter –Finished (Jim Mason & Terry Bender) –To be shipped in January, installed in May 2006 Hot spare –Shelter finished –Instrument components being reviewed, documented, ordered, fabricated as necessary –Temporarily supporting seven NOAO ETS staff –Expect completion in FY 2007 –Located at Tucson on standby –How to operate?

14. The new shelters

15. Data Management & Analysis Center Hardware –Five Linux servers –60 TB disk (with mirroring) –Two Sun servers –LTO 180 tape library Linux –Porting slowly underway –Precision issues GRASP –Last monolithic release –Adopting CVS of individual major modules for more flexibility and quicker pipeline upgrades

16. Data availability Nearly 50 consecutive rotations of local helioseismology results Ring diagram flow data on the web Merged velocity images on the web Frequencies up through end of 2004 Farside images every 12 hours on the web Full-disk single-site magnetograms every 20 min on the web

17. Pipelines status Calibration –Automated image rejection (AIR) completed –Running on single Sun server Global p modes –Improved angular registration code (COPIPE II) Ring diagrams –Unchanged since last year Farside –Routinely running –Needs integration of full hemisphere analysis Time-distance –Ready to go, installation deferred due to resource constraints Magnetograms –High priority (modulator & STEREO Launch) –Gordon Petrie lead –Zero point correction for data from original modulator (Richard Clark) –Histogram equating for merging (Harry Jones & Cliff Toner)

18. Major Meetings 2005: –Boulder HAO summer school –Bob Stein tribute 2006: –SOHO 18/GONG 2006/HELAS 1, Sheffield UK –IAU General Assembly and Joint Discussion
