Yohkoh SoHO TRACE Closing Remarks by ER Priest In recent pasthuge advances from
Kosugi Metcalf ? (born Sept 23, 06) ひので Wow ! Fantastic mission Exciting discoveries ! Brilliant set of talks ! Tsuneta Clearly, producing next great advances in our subject So what learnt so far ? What expect in future ?
Performance: Ichimoto, Hara, DeLuca EUV Imaging Spectrometer(EIS) Solar Optical Telescope(SOT) X-ray Telescope (XRT)
1. Magnetic Field of Photosphere 3min 4min 5min 6min 2min t=0min 1min Vertical field (CP) Horizontal field(LP) Continuum 2.5 arcsec SOT Bruce Lites: *** Discovery of Ubiquitous Horizontal Fields apparent Bhor=5Bvert (tube aspect ratio 10) Flash Gordon: “He who controls magnetism controls the UNIVERSE” ! Ryohko Ishikawa: -- Emerge in granules -- preferred direction in plage, none in Q. Sun
Saku Tsuneta:*** Polar B = kG vert trumpets +ubiquitous horizontal field Clare Parnell: *** Q. Sun mag.elements to 1016 Mx(~30<MDI, 50% more flux); flux distrib is power law; smallest not yet resolved. Rolf Schlichenmaier: Properties similar to radiative magnetoconvection simulation Ted Tarbell: *** Chromospheric magnetograms[Mg Ib] --> intermittent upflows in cancellation
2. Spicules Yoshino Suematsu / Viggo Hansteen: ***Stunning new discovery in Ca II H Lateral oscillations, like swaying straw, [v~20 km s-1, periods 1-3 min [2-6?]] Double threads -- spinning; Alfven waves -- ? Generated by reconn -- ?accel solar wind
3. Prominences Petr Heinzel: origin of fine- scale structure Alphonse Sterling: Eruption of Hinode filament -- due to flux emergence & cancellation
Gemma Attrill: Fil eruption/CME -- > coronal wave w. bright front + coronal dimming Shinsuke Imada:Observed upflow in dimming region Takaaki Yokoyama: Prominence has inverse polarity David Williams: Reconnection, rotation, expansion before filament eruption
moat region penumbra 4. Sunspots Jan Jurcak: Penumbra fine structure -- puzzling KiyoshiIchimoto: Complex nature up- & downflow in penumbra Mashito Kubo: ***Moving magnetic features --> convection detaches flux from spot
Tetsuya Magara: Phases of motion of Dec 06 sunspot group; Use velocity info for 180 degree ambiguity.
XRT & EIS Emerging Flux Takashi Sakurai: Corona brightens in XRT after magnetic flux increases Mark Cheung: Flux is fragmented by granulation as it emerges in a radiative MHD simulation
King of Jets is happy 2. XBP & Jets Suguru Kamio: Jets ejected from XBP Junichi Kotoku: XBP have complex structure & evolve dynamically Shibata model Deb Baker: discovered post-jet enhancements
Kazunari Shibata: *** discovery of ubiquitous Ca H jets accelerated by ubiquitous reconnection [of Close & Parnell]. Sugure Kamio: properties in coronal hole Yukio Katsukawa: *** disovered microjets in penumbra Ed DeLuca:QSL structure of XBPs
3. Coronal Holes Ryouhei Kano: measured temp structure Werner Curdt: structure of polar plumes with SUMER+EIS
Leon Golub: *** Shear changes in flares; *** Sigmoid is a pair of J’s 4. Flares/CME’s Len Culhane: *** Flow & turbulence in flare loops w. EIS
Nonlinear force-free extrapolations: Stephane Regnier: Calculated free energy as difference nonlin & lin fff. Marc DeRosa: Model Hinode preflare --> strongest current v. low Satoshi Inoue: Sigmoid is complex multiply sheared loops
Louise Harra: Reviewed Dec 2006 flares: *** observns reconnection region Simon Plunkett: Reviwed 3D Stereo view of corona Ron Moore: CF magnetic bubble model of CME w. obsns
Kerry Korreck:X-ray luminosity as fun of mag. flux Masumi Shimojo: Observations of particle acceleration on Dec 13, 2006 Rim Turkmani: Models electron acceleration in a loop & at the feet.
Observable effects of current sheet in flares Dan Seaton: Tetsuya Watanabe: Observed very high-T lines in solar flares (20 MK, Fe XIV) Hugh Hudson: proved that he is a poet ! and that preflare plasma is thin and cold.
5. Active Regions - dynamic & fine structure ! Taro Sakao: Extended a.regions/ *** discovered strong outflows Helen Mason: *** Review T & n diagnostics
Fabio Reale: *** T map with fine structure Jane Noglik: Temp. coronal loops -- ? multithermal Keiichi Matsuzaki: Multi-T observations with EIS --> magnetic junk field Peter Young: Secrets of making n maps
***Temperature maps of full Sun -- new classification of coronal structures Noriyuki Narukage: Giulio del Zanna: Many loops cooling due to slow emergence & reconnection Kevin Reardon: Temp from photon spectroscopy [XRT]

Future ? Just a beginning ! Hinode is Gold Mine -- wealth of discoveries 2. Especially when combine instruments -- encourage collaborations, young people 3. Will learn much more about fundamentals of -- nature photospheric B - how formed, evolves, disappears -- cause spicules -- origin flares, cme’s -- nature prominences -- cause coronal heating -- ………
