Symposium S5  22 – 23 June 2015

The Sun under the microscope

Aims and scope

During the last years, there have been considerable advances in high resolution Solar Physics, reaching spatial scales in the range from 100-300 km. Telescopes like the Swedish Solar Telescope (SST) at the observatory of El Roque de los Muchachos, the National Solar Observatory's Dunn Solar Telescope (DST) at Sunspot, and the Vacuum Tower Telescope (VTT) at El Teide observatory have significantly improved their observing capabilities. The result of those efforts is a better understanding of the photospheric and chromospheric magnetism, and the connectivity of those layers. The recently launched Interface Region Imaging Spectrograph (IRIS) mission complements the successful Hinode satellite and Sunrise balloon by observing the high chromosphere and the transition region with unprecedented spatial resolution, providing interesting information expanding the ground-based results. The corona is also monitored at different temperatures with high resolution by the Solar Dynamics Observatory (SDO) satellite, providing clues to understand the mechanisms that heat the outer solar atmosphere up to million degrees.

Telescopes that are starting their lifetime, like GREGOR (El Teide), the New Solar Telescope (NST; Big Bear Solar Observatory), and the New Vacuum Solar Telescope (Fuxian Solar Observatory) are expected to deliver soon even better data that will improve our knowledge of the fundamental processes that govern the solar atmosphere and provide a more accurate and coherent vision of the physical phenomena in the different layers.

This symposium is aimed at presenting the best, up-to-date results from high-resolution solar observations with ground and space-based instrumentation. It will bring together the whole worldwide high-resolution Solar Physics community and sumarise the latest scientific achievements, including high resolution numerical simulations and diagnostic techniques, as a way to get prepared for the next generation of solar telescopes: European Solar Telescope (EST, Canary Islands) and Daniel K. Inouye Solar Telescope (DKIST, Hawaïi).


We have planned 6 invited reviews (IR) with a duration of 20 min, 7 invited talks (IT) with a duration of 15 min, and 25 contributed talks with a duration of 10 min. Depending on the number of requested contributed talks, and up to 20 posters, will have a 1 min presentation at the end of some sessions.

  • Session 1: Diagnostic techniques and numerical simulations
  • Session 2: High resolutions observations of the solar photosphere
  • Session 3: High resolutions observations of the solar chromospere, transition region, and corona
