29 Aug '13

Dear all, We are pleased to announce the release of a new EIS nugget by Louise Harra, Sarah Matthews, J. L. Culhane, Mark Cheung, Eduard Kontar, Hiro Hara This month we look the location of non-thermal velocity in the early phases of a large flare - revealing a pre-eruption flux rope? Please visit the nugget here: http://solarb.mssl.ucl.ac.uk/SolarB/eisnuggets.jsp We welcome nugget contributions from the community. Please contact Deb Baker or Lucie Green if you are interested. Best wishes, Deb Baker -- Dr. Deb Baker UCL – Mullard Space Science Laboratory Email: Deborah.Baker(a)ucl.ac.uk Tel: +44 (0) 1483 204 179

Announcing a new RHESSI Science Nugget
by Hugh Hudson 07 Aug '13

07 Aug '13

No. 205, "Acceleration-region Densities," by Sa"m Krucker and Marina Battaglia. Independent constraints on the densities of ions and non-thermal electrons point to bulk acceleration. See http://sprg.ssl.berkeley.edu/~tohban/wiki/index.php/Acceleration-region_Den… 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.
