We welcome almost any contribution to the RHESSI Nuggets. The topic may wander some distance away from specifically RHESSI results if it is generally interesting. See http://sprg.ssl.berkeley.edu/~tohban/wiki/index.php/RHESSI_Science_Nuggets for these and others. Comments about specific flares can often be found by searching for their SOLyyyy-mm-dd identifier from this home page.… continue to the full article
