The energy released during solar flares (on many scales — temporal, spatial, and energetic) often manifests itself in the form of increased SXR and EUV emission due to either direct heating in the corona, or the transport of energy to the chromosphere and subsequent expansion and evaporation. This emission contains a wealth of diagnostic information that can shed light on the physical properties of the heated plasma, such as temperature, density, velocity, and energetics, thereby helping us understand the energy release and transport mechanisms. Coincident observations between RHESSI and other longer wavelength instruments have significantly advanced our understanding of flare heating over the years. We hereby solicit talks that focus on joint flare observations between RHESSI and MinXSS, SDO (EVE+AIA), Hinode (EIS+XRT), STEREO/EUVI, GOES (XRS+EUVS), IRIS, and others. This session also welcomes discussions on modelling these emissions.
