No. 322, “Observation of Cosmic-Ray Spallation Events from SoHO,” by Serge Koutchmy and Ehsan Tavabi. LASCO’s images capture high-energy nuclear interactions from cosmic-ray hits.

No. 323, “To beam or not to beam – that is (still) the question,” by Paulo Simoes and Hugh Hudson. Descriptions of the lower solar atmosphere of flares ca. Cycle 21 sound surprisingly current.

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.
