11/10/05 H1:Local Helioseismology I: Current Issues Science Goal and Approach Sessions Chair(s): Kosovichev/Toomre Status: [draft]

11/10/05 S-2: Science questions and tasks Local helioseismology already provides unprecedented views of the Sun's interior 3D structures and flows, sunspots, active regions, and even the far-side activity. These all remain critical areas for achieving the HMI science objectives.

11/10/05 S-2: Science questions and tasks What are the primary targets and most critical issues of these investigations? How can we extend the local helioseismology measurements through the convection zone? What is needed to understand small-scale magnetic fields, sunspots, and active region? How best can we image the tachocline and 3D structures?

11/10/05 S-2: Science questions and tasks What is needed to adequately measure the meridional and other 3D flows? How do we link the helioseismic measurements on different scales to the SDO photospheric, coronal and irradiance data? How can we develop the predictive capabilities of local helioseismology?

11/10/05 S-3: Science context What progress has already been made? Where do we expect answers before launch? Where do we plan to concentrate our efforts?

11/10/05 S-3: Science context - Agenda 3:15-3:30 Turbulent magnetohydrodynamics of the Sun: big questions and key targets for HMI - J.Toomre 3:30-3:40 Time-distance helioseismology of the deep interior - T.L.Duvall, Jr 3:40-3:50 Local helioseismology at small scales - T.Sekii 3:50-4:00 Ring-diagram flow maps: from large to small tiles - D.Haber 4:00-4:10 Far-side holography imaging for HMI - P.H.Scherrer 4:10-4:20 European Local Helioseismology and HELAS - L.Gizon 4:20-4:35 General discussion 4:35-4:45 Summary, Organization of the Local Helioseismology Working Group - A.G.Kosovichev

11/10/05 S-4: Implementation What do we need to make progress on the science questions in general? –Should a TR&T focused topic be made? Discussion point –Suggestion for Helioseismology Working groups Time-Distance & Holography Global Helioseismology & Rings Local Helioseismology Comparison (LoHCo) –Observables, models, codes, resources, techniques, people … –Schedules, meetings, splinters, etc.
