Abstract:
In recent years several observation of white-light flare features in the low corona using data from the Helioseismic and Magnetic Imager onboard the Solar Dynamics Observatory have been reported. We present the first results of a white-light flare catalog based on SDO/HMI 6173A Intensity observations and the RHESSI flare catalog. We selected flares during 2011 and 2013 with GOES classification above M1.0 that were fully or partially observed by RHESSI as reported in the RHESSI flare catalog. We found that at least one third of the flares present white-light enhancement in the 6173A line and at least one fifth of the events show above the limb white-light sources. We will also discuss the results of a comparative analysis between the Hard X-ray and white-light positions. This analysis show the statistical average-height variation using the analysis technique described by Matsushita et al. 1992.
