Announcement: solar flare session at IAGA **************************************************************** "Multi-spectral studies of Solar flares ", session 4.3 at the XIIth Scientific Assembly, International Association of Geomagnetism and Aeronomy (IAGA), to be held in Merida Yucatan Mexico, August 26-31, 2013. http://www.iaga2013.org.mx Description: Solar flares are often viewed as the most dramatic and powerful magnetic explosions in the solar system. After the deep solar minimum of 2008-2009, the solar activity is on the rise and the Sun has already produced a number of spectacular solar flare events. Despite of the substantial progress made over the last few decades in understanding the physics of solar flares, there are many open questions. Over the last few years, the unprecedented variety of the spacecraft and ground based observations of solar flares become available: from the high energy gamma and X-ray emission (RHESSI, Fermi), through EUV, optical (SDO, Hinode, STEREO) range down to radio frequencies (STEREO, Wind). These space-based observations are substantially enhanced via a number of ground based observations, notably with solar radio observatories. The session aims to bring together the diverse solar flare community to discuss the latest observations, modelling and theoretical developments in the area of solar flare physics. It will focus on correlative analysis of simultaneous multi-spectral observations of solar flare phenomena addressing the key science questions of magnetic energy release, energetic particle acceleration and transport, the response and emissions in the solar atmosphere and the heliosphere. In addition, the connection of the observational results with the modelling and theoretical developments in this area will be discussed. ************************************************************************** This message was posted to the CESRA email list http://www.lesia.obspm.fr/cesra/
