Hello, The seminar, entitled "Solar flare energetic particles: What have we learned with RHESSI?" will be given by Dr. Eduard Kontar from the University of Glasgow. Time:Tuesday 8 November at 15:15 Place: Ångströmlaboratoriet, room # 111167 Abstract: **************************************************************** Recent launch of Ramaty High Energy Solar Spectroscopic Imager (RHESSI) opened new horisons in solar flare physics. I will discuss the recent progress in the diagnosis of flare energetic particles with RHESSI with the emphasis on high resolution Hard X-Ray spectroscopic data. New spectacular photon data findings, some advances in theoretical aspects of their use as well as energetic particle diagnostics will be highlighted. ************************************************************** Everybody are welcome! -- Mykola Khotyaintsev Astronomy & Space Physics Dept., Uppsala University
