My primary interest is to revisit the HXR-UV relation using RHESSI/TRACE data. I spent long time on this subject using HXT/TRACE, and found that TRACE data are often saturated for flares that are intense enough for image reconstruction by HXT. I believe the higher sensitivity of RHESSI will alleviate the problem of saturation of TRACE data. Another thing I would like to do is to follow weak coronal sources (they sometimes move on the basis of HXT), which may tell us something about the possible contribution of flares to SEP events.
