Description
Solar flares are the most powerful explosions in the solar system, accelerating large amounts of particles in the process. They are readily observed in X-ray and EUV wavelengths. Thus X-ray and EUV observations are an important diagnostic tool of various plasma parameters of the solar atmosphere during flares and also provide important information on particle transport properties. With the RHESSI satellite it has become possible to observe X-ray flare sources with the necessary accuracy for such diagnostic. With the Solar Dynamics Observatory we now have high cadence, high resolution EUV data at various wavelengths to complement X-ray observations.
I will present recent results of combined X-ray, EUV and white light observations. Examples will be given of how these observations are
used to infer parameters such as X-ray and EUV source heights and coronal loop densities.
