No. 181, Dense Loop Flares, by Jingnan Guo and Gordon Emslie. Direct electron mapping teaches us about the structure of electron acceleration in flares. See

Older Nuggets are available at http://sprg.ssl.berkeley.edu/~tohban/wiki/index.php/RHESSI_Science_Nuggets (the current series, 2008-present), and at http://sprg.ssl.berkeley.edu/~tohban/nuggets/ (the original series, 2005-2008).

We publish these at roughly two-week intervals and welcome contributions, which should be related, at least loosely, to RHESSI science.
