  2. New Solar Telescope at Big Bear 7/02/2011 XXV IUGG/IAGA, Melbourne, Australia

  3. 7/02/2011 XXV IUGG/IAGA, Melbourne, Australia

  4. Coude room optical layout 7/02/2011 XXV IUGG/IAGA, Melbourne, Australia

  5. Magnetic Fields Measurements from NST and SDO NST InfraRed Magnetogram SDO magnetigram 7/02/2011 XXV IUGG/IAGA, Melbourne, Australia

  6. Hinode Satellite (Left) and NST (Right) Images of the Sun the Same Time/Place (Abramenko et al. 2010, ApJL, 725) Hinode/G-band NST TiO 7/02/2011 XXV IUGG/IAGA, Melbourne, Australia

  7. Bright points (magnetic flux tubes) are NOT ribbons, but always form chains of beads

  8. NST observations verify simulations of granula evolution : formation of bright granula lane moving inside the granula is accompanied by emergence of horizontal rotating vortex tube and tiny jets (Yurchyshyn et al. 2011 ApJL, accepted) 7/02/2011 XXV IUGG/IAGA, Melbourne, Australia

  9. Pores and penumbra formation , photospheric signatures of flux emergence (Lim et al, ApJ submitted) 7/02/2011 XXV IUGG/IAGA, Melbourne, Australia

  10. Dynamics and statistics of photospheric bright points (BPs) A set of 648 TiO images: AO corrected Speckle reconstructed Aligned Destretched Image size: 14 x 14 Mm, or 510 x 510 pixels Cadence 10 s 17539 BPs were detected and tracked 7/02/2011 XXV IUGG/IAGA, Melbourne, Australia

  11. 77 km Size distribution of BPs: minimum size of flux tubes is not reached yet (Abramenko et al. 2010, ApJL, 725) 7/02/2011 XXV IUGG/IAGA, Melbourne, Australia

  12. Magnetic diffusion in the photosphere occur in a super-diffusion regime on scales below 600 km and shorter than 10 min (Abramenko et al. under preparation) Details: Tuesday, Jul 5, 16:30 talk in this room 7/02/2011 XXV IUGG/IAGA, Melbourne, Australia

  13. 7/02/2011 XXV IUGG/IAGA, Melbourne, Australia

  14. Diffusivity: some definitions: 7/02/2011 XXV IUGG/IAGA, Melbourne, Australia

  15. Details: Tuesday, Jul 5, 16:30 talk in this room 7/02/2011 XXV IUGG/IAGA, Melbourne, Australia
