  1. Summary of 2008 Science Team Meeting

  2. Collaboration With Dr. Wiegelmann • 1. NLFFF extrapolation, leading person: Ju Jing. Objective: adapt codes to BBSO data, evaluate the effect of saturation, ready for VIM/IRIM data and SDO data. Other applications: apply to chromospheric data (Na Deng); compare with radio data (Jeongwoo Lee and Dale Gary); Flaring AR field connectivity (Chang Liu). Data from Mees, SOLIS, and VLA will be explored.

  3. Collaboration With Dr. Wiegelmann • 2. STEREO 3-D imaging Yan Xu and Vasyl Yurchyshyn with Dr. Thomas’ student Ms. Feng • 3. Field Line Tracing using Halph Contact person in Thomas’ Group: Inhester

  4. Collaboration With Prof. Pengfei Chen • Reconnection and electron acceleration (Chang Liu and Yan Xu), microphysics in reconnection region • Prominence oscillation (Ju Jing and a student) • Flare model to explain our findings: penumbral decay, neutral line enhancement, ribbon contraction etc. (Wang)

  5. Collaboration with Prof. Denker • VIM (Chang and Na) • 2-D Spectropolarimetry • Real-time speckle—new codes, combination of narrowband and broadband, AO function into consideration

  6. Enhanced Collaboration with OVRO Group • Synthesized modeling of 3-D structure combining optical and radio data (Jeongwoo Lee) • Reconnection, small/large-scale turbulence and plasma motions, and particle acceleration (Gregory Fleishman)

  7. High Level Responsibility • Vasyl Yurchyshyn: SDO, Halpha Network, Heliospheric missions (ICME) • Ju Jing: Hinode, NLFFF Extrapolation, Artificial Intelligence • Chang Liu: RHESSI, OVRO • Xu Yan: STEREO • Valentina Abramenko: SW, Structure Function • Na Deng: LWS, AR structure • Wenda Cao: BBSO Instrumentation

  8. Collaboration Plan

  9. Evolution of Magnetic Fields Associated with Flares • Ju Jing: 3-D field structure and electric current • Changyi Tan: Eveshed and shear flow • Yixuan Li: Inclination angle and temperature structure (model sunspot for FASR) • Valentina Abramenko: Structure function • Sunghong Park: Helicity Injection

  10. CME/ICME • Vasyl Yurchyshyn, Yan Xu and Vincent Tagliamonti Objective: physical connection among surface magnetic structure, CMEs and ICMEs

  11. RHESSI Science and Magnetic Reconnection • Chang Liu: Small and large scale magnetic structure of flares • Yan Xu and Chang Liu: Imaging Spectroscopy; Magnetic reconnection rates. Direct imaging of electron maps may be very useful. Collaborate With Pengfei and Jeongwoo

  12. Artificial Intelligence for Solar Activity Detection • Ju Jing, and Yuan Yuan, Prof. Frank Shih Prof. John Jeng (Montclair U.) Filament Detection Flare Detection EFR Detection Flare Prediction Implementation of developed tools is extremely important.

  13. Corona Heating and Coronal Hole Study • Valentina Abramenko and Changyi Tan • Complexity and Poynting flux • Hinode observation and model with magnetic fields

  14. Kinetics of CME and Filament Eruption • Yan Xu and a student STEREO Trajectory of Eruption Ribbon Contraction Failed CME

  15. NIR Science • Wenda Cao, Yan Xu, Na Deng and Sung-Hong Park WL Flare Faculae Intranetwork Fields (refer to J. Harvey paper) Multi-layer, Multi-wavelength comparison

  16. 3-D AR Structure • Na Deng , Ju Jing, Carsten Denker, Valentina and Jeongwoo Objective: Observations from Photosphere, Chromosphere to Corona. Comparison the observation with NLFFF extrapolation. VLA observing time will be applied.

  17. Space Weather Prediction • Flare: Ju Jing, Yuan Yuan and Valentina • Geo-magnetic Storm: Vasyl

  18. Service Function • Halpha Network maintenance and further development, Vasyl and a new Post-doc • Inversion Codes for IRIM and VIM, lead by Wenda Cao with help from Chang Liu, and Sung-Hong Park • Vector magtogram data processing (180-deg ambiguity resolution, pre-processing, NLFFF extrapolation), Ju Jing
