Flare SOL2012-07-06: on the origin of the circular polarization reversal between 17 GHz and 34 GHz by Altyntsev et al.* http://cesra.net/?p=1578<HTTP://cesra.net/?p=1578> Observations of a radio-quiet solar preflare by A. Benz et al.* http://cesra.net/?p=1562<HTTP://cesra.net/?p=1562> Predicting Flares and Solar Energetic Particle Events: The FORSPEF Tool by A. Anastasiadis et al.* http://cesra.net/?p=1551<HTTP://cesra.net/?p=1551> —————— CESRA publishes Highlights of Solar Radio Physics aka CESRA Nuggets approximately every two weeks. These short communications are written in the language accessible to a non-expert in the specific area and designed to keep solar and heliophysics communities informed and up-to-date about current research. The highlights can be followed, discussed, commented and shared via https://www.facebook.com/solarcesra/ and https://twitter.com/CESRA_community [University of Glasgow: The Times Scottish University of the Year 2018]

Announcing RHESSI Science Nuggets in October 2017
by Hugh Hudson 27 Oct '17

27 Oct '17

No. 309, “Electron Scattering in the Flaring Corona,” by Sophie Musset: Diffusive transport may contribute to the trapping of energetic electrons in coronal hard X-ray sources. No. 310, “Valderrama in the 21st Century,” by Hugh Hudson: A newly-describd white-light flare from the 19th century, chronologically the third-ever observed flare. 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/forthe 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.

by Hugh Hudson 23 Sep '17

23 Sep '17

No. 306, “The Last Best Flare of Cycle 24,” by Sa”m Krucker and Hugh Hudson: Right on schedule, Cycle 24 has produced a great flare (and a GLE). No. 307, “The Kelvin Force and Loop-Top Concentration,” by Kiyoto SHIBASAKI: New physics can explain the perplexing overpressure at the flare looptop regions. No. 308, “The Power of Turbulence,” by Nic Bian: Turbulent energy content may underlie flare energy transfer, recconnection, and particle acceleration. 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.
