Announcement: Prague solar symposia to be hold during 26 IUGG General Assembly A message from Gregory D. Fleishman: We would like to announce the Prague solar symposia to be hold during 26 IUGG General Assembly, June 22 - July 2, 2015. There will be a few workshop dedicated to Quiet Sun and Active Regions (A32), solar flares (A30), and turbulence (A29). Please note that the deadline for the abstract submission is January 31, 2015. The full announcement for A32 is below. --- IUGG 2015 assembly; Prague, Czech Republic, from the 22nd of June to the 2nd of July 2015: A32 Studies of the Quiet Sun and Active Regions 26th General Assembly of the International Union of Geodesy and Geophysics (IUGG) www.iugg2015prague.com/ is approaching with the following deadlines: January 15, 2015 Grant applications (CLOSED); January 31, 2015 Abstract submission DEADLINE; March 31, 2015 Notification to successful grantees. There will be a number of Solar Physics (Div. IV) Symposia www.iugg2015prague.com/iaga-symposia.htm including the first time organized Symposium dedicated to the Quiet Sun and Active Regions (A32, see its announcement below). Given a series of new space and ground based observing instruments, it is timely to deeply discuss the present status and state-of-the-art of the observational, theoretical, and modeling studies in this area. Therefore, the organizers encourage all interested researches to take part in Symposium A32 and take advantage from having many other related symposia happening just next door within this same IUGG 2015 assembly www.iugg2015prague.com/scientific-program.htm Looking forward to seeing you in Prague. See the symposium manifesto below. A32 Studies of the Quiet Sun and Active Regions (Div. IV) Recent years have brought a significant progress in understanding of the structure and dynamics of the quiet Sun and active regions (QSAR) down to very small scales both observationally and through state-of-the-art 3D MHD simulations. These studies confirm that QSAR are not steady, but rather very dynamic with a large number of physical processes involved. In particular, it has become clear that the individual solar layers are strongly coupled with each other and must be considered consistently, i.e. as an entity. Thus, the goal of this session is to bring together researches from various sub-areas of QSAR studies to envision a bigger synthetic picture of the QSAR. The emphasis of the session will be given to new multi-wavelength observations in decimeter, microwave, millimeter, sub-millimeter, infrared, optical, UV and X-ray bands from already available instrument (e.g., SDO, IRIS, NST, ALMA, LOFAR, EVLA) as well as microwave facilities, which are under construction/expansion now (e.g., EOVSA, mSSRT) on one hand and to state-of-the-art simulations and modeling (MHD, NLFFF, thermal structure, radiative transfer, and synthetic diagnostics) on the other hand. The different instruments/wavelengths probe different quantities/physical regimes/layers in the solar atmosphere, which makes the multi-wavelength approach so important for trying to understand the COUPLED atmospheric layers. We anticipate intensive interaction between the observational and modeling components of the session both aimed towards a better and comprehensive understanding of the QSAR physics and also towards the development and improvement of diagnostics of the corresponding magnetic and thermal structures using the available observational tools. Overall, the session aims to bring together the diverse solar community to discuss the latest observations, modeling and theoretical developments in the QSAR area of solar physics. In addition, the connection of the observational results with the modeling and theoretical developments in this area will be discussed.
