SOLARNET IV MEETING The Physics of the Sun from the Interior to the Outer Atmosphere

SESSION 0: SOLARNET PROJECT SOLARNET Introductory talk: “The SOLARNET project” Author(s): Manuel Collados Abstract: SOLARNET is an EU-funded project aimed at preparing the European Solar Physics research community for the operation of the European Solar Telescope (EST). To achieve this ambitious goal, the project has addressed a number of activities to optimise the use of the major present European highresolution solar telescopes (GREGOR, SST, THEMIS, VTT) and instruments (IBIS and ROSA operating at DST). The experience gained with these activities will serve as a basis to determine the best way to operate EST and optimise its scientific return to the research community. The following achievements can be mentioned: (i) granting access to world-wide observers to the most powerful European solar observing facilities; (2) implementation of a service mode as a complement to the standard PI-mode; (3) development of standard pipelines for all instruments to produce science-ready data; (4) generation of rules for standard data archiving and retrieval; (5) creation of databases with ground-based data that may be accessed with virtual observatories tools; (6) development of new generation instruments as prototypes for the instrumentation of EST; (7) definition of a global network (SPRING) for continuous ground-based full-sun observations to help prepare and support high-resolution observations; (8) seeing measurements and AO/MCAO optimisation analyses; (9) preparation of the next generation of solar researchers with the organisation of a number of schools and with an efficient student mobility programme; (10) organization of a number of scientific meetings to foster synergies between different research communities; (11) establishment of contacts with the European industry; and (12) disseminate solar research with outreach activities. All these activities will be described in this contribution making emphasis on the importance of SOLARNET for the solar physics community and EST.

Poster: “SOLARNET WP30: SOLAR PHYSICS NETWORKING” Author(s): Francesca Zuccarello & the SOLARNET TEAM Abstract: Aim of this work-package was to foster collaborations among different solar physics groups, promote the interaction and cooperation among researchers of different level of expertise, as well as to encourage and promote synergies with other fields. The actions undertaken in this work-package have been: exploitation of groundand space-based data; enhancement of collaborations with other communities and projects; promotion of collaborations between the new generation of scientists and experienced researchers through short stays and training actions to acquire competences in relevant fields of solar physics. More specifically, the first task of this WP was to organize four Meetings whose objective was to put in contact different solar physics communities and researchers involved in different fields of research. The second task concerned the Mobility of young researchers with the goal to reinforce the contacts between different groups and to allow young researchers to begin early to establish international collaborations. The third task concerned the organization of: a) Summer/Winter Schools for PhD students and novel post-doc researchers on topics related to the development of new instrumentation for solar observations, diagnostic tools, hot solar research topics and fields of mutual interest for solar and stellar physicists; b) Thematic Workshops matched with the training schools.

Poster: “Solarnet WP80 Synoptic observations: Solar Physics Research Integrated Network Group (SPRING)” Author(s): Markus Roth, Frank Hill, Michael Thompson, Sanjay Gosain Abstract: High-resolution telescopes (such as SST, GREGOR and the future EST and ATST) allow observations of only a small fraction of the solar surface. Real-time context data showing the large-scale dynamics and magnetism at different layers of the solar atmosphere are crucial to understand the global behavior of solar phenomena. However, despite the amount of information coming from space and ground-based full-Sun telescopes, real-time information about the variation of important parameters such High-resolution telescopes (such as SST, GREGOR and the future EST and ATST) allow observations of only a small fraction of the solar surface. Real-time context data showing the large-scale dynamics and magnetism at different layers of the solar atmosphere are crucial to understand the global behavior of solar phenomena. However, despite the amount of information coming from space and ground-based full-Sun telescopes, real-time information about the variation of important parameters such as velocities, magnetic field and intensity at different solar layers is stilllacking. To this aim, a network of telescopes with a small aperture but a large field-of-view can provide useful data to prepare observing campaigns with large-aperture high-resolution telescopes and complement the data taken with them. Distributed in a world-wide network, these small apertures can represent an invaluable supporting tool for coordinated observations with the major infrastructures. Within this Joint Research Activity under Solarnet, the definition of an adequate network of small telescopes, as well as the most suited instrumentation was addressed. Poster: “SOLARNET WP 100: Access to Science Data Centres. Space missions. ” Author(s): Mats Carlsson Abstract: The SOLARNET workpackage 100 provides access to Space data through three Science Data Centres: Hinode and IRIS data through the Hinde Science Data Centre Europe in Oslo, SDO AIA data through the Belgian Web Incessant Screening for SDO Mission in Brussels and SDO HMI data through the German Science Center for the Solar Dynamics Observatory in Göttingen. We here descirbe the three data centres and usage statistics throughout the SOLARNET period.

SESSION 1: SOLAR INTERNAL STRUCTURE FROM HELIOSEISMOLOGY Invited review: “Helioseismic probes of the solar interior” Author(s): Anne-Marie Broomhall Abstract: Helioseismology uses the Sun’s natural oscillations to probe beneath the surface of the Sun. Over the past several decades helioseismology has proven extremely successful at providing insights into the interior of
