Announcing a new RHESSI Science Nugget, No. 239
by Hugh Hudson 27 Oct '14

27 Oct '14

"A Record-Setting CMEless Flare," by Sam Freeland and Greg Slater. Active region 2192 has produced many major flares, but none with CMEs yet. 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.

Announcing RHESSI Science Nugget No.238
by Hugh Hudson 14 Oct '14

"The Formation of Kappa Distributions in Solar Flares," by Nicolas Bian and Duncan Stackhouse. It turns out that a kappa distribution can arise naturally from Coulomb collisions, as in a coronal thick target. 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.

Input for RHESSI Senior Review Proposal
by Dennis, Brian R. (GSFC-6710) 06 Oct '14

06 Oct '14

Dear RHESSI'ers, We are soliciting input for the NASA 2015 Senior Review of Heliophysics operating missions. Please send us summaries of your RHESSI-related work over the last two years and, as importantly, your plans for future work. To help you decide what will be most useful to us in preparing the proposal, here are excerpts from the Instructions to Proposers: The objectives of the 2015 HPD Senior Review for MO&DA is to assess the science merits and performance of these 15 missions (in alphabetical order): ACE, AIM, CINDI, Hinode, IBEX, IRIS, RHESSI, SDO, STEREO, THEMIS, TIMED, TWINS, Van Allen Probes, Voyager, and Wind. Performance factors to be evaluated will include mission scientific productivity, technical status, budget efficiency, data quality and accessibility, and contribution to the "Heliophysics System Observatory (HSO)." "The period for this Senior Review will cover FY16 to FY20. Each mission that is invited to this Senior Review will submit a proposal outlining how its science investigations will benefit the Heliophysics research objectives. These objectives and focus areas are described in the Science Plan for NASA's Science Mission Directorate 2014" - the SMD Science Plan available at - http://science.nasa.gov/media/medialibrary/2014/05/02/2014_Science_Plan-050… Previous Senior Review proposals and panel reports at the following location: http://hesperia.gsfc.nasa.gov/rhessi2/home/mission/documents/ Finally, please make sure that all of your RHESSI-related publications are included in Markus Aschwanden's list at the following web site: http://www.lmsal.com/~aschwand/publications/rhessi.html<http://www.lmsal.com/%7Easchwand/publications/rhessi.html> Thanks and best wishes, Sam Krucker, Brian Dennis, and Albert Shih Samuel Krucker, RHESSI PI Space Sciences Lab.
