No. 332, “Photospheric response to a flare,” by Mike Wheatland: Sudden changes in the magnetic field in the lower atmosphere associated with particle acceleration.

No. 333, “Coronal hard X-ray sources revisited,” by Brian Dennis. Reporting some over-interpretation of the evidence for “coronal thick targets”.

No. 334, “White-light emission and non-thermal electrons,” by Kyoung-Sun LEE. An intimate relationship between accelerated electrons and visible continuum emission.

See http://sprg.ssl.berkeley.edu/~tohban/wiki/index.php/RHESSI_Science_Nuggets listing the current series, 2008-present, and http://sprg.ssl.berkeley.edu/~tohban/nuggets/ for 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.
