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

14 Oct '14

"The Formation of Kappa Distributions in Solar Flares," by Nicolas Bian and Duncan Stackpole. 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. We publish these at roughly two-week intervals and welcome contributions, which should be related, at least loosely, to RHESSI science.

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.

RHESSI Science Nuggets in September
by Hugh Hudson 29 Sep '14

29 Sep '14

No. 237, "The Balmer continuum observed from IRIS!" by Petr Heinzel and Lucia Kleint. For the first time we have clear and direct observations of the Balmer continuum, from space. No. 236, "Energy goes up... but doesn't come back down! Coronal heating?" by Brian Welsch. The Poynting flux responsible for coronal heating may have been spotted. No. 235, "Which detectors can I use to analyze this flare?" by Brian Dennis and Kim Tolbert. A new Browser feature helps to answer this question. No. 234, "RHESSI resumes observations," by Albert Shih and Sa"m Krucker. Back to normal, the anneal was a success. 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.

MAX MILLENNIUM NEWS 24 September 2014 CONTENTS 1. NEW COORDINATED FLARE OBSERVING PLAN 2. E-PRINTS POSTED IN THE PAST WEEK 3. FROM THE EDITOR ===================================================================== 1. NEW COORDINATED FLARE OBSERVING PLAN From Ryan Milligan <r.milligan (at) qub.ac.uk> In October 2014, the Dunn Solar Telescope (DST) of NSO will conduct a full month of Service Mode Operations dedicated to observations of solar flares. The campaign shall utilize the full suite of instruments at the DST (ROSA, IBIS, and FIRS), and will be supported by SDO, Hinode, IRIS, and RHESSI when possible. The Max Millennium Chief Observers have therefore formulated a new Max Millennium Observing Plan (MM_OP) - MM#020 DST Service Mode Support - that will be implemented throughout October (and future Service Modes) whenever solar activity is at moderate levels and seeing conditions at the DST are favorable. The specific observing plans for each instrument for this and other MM_OPs can be found at http://solar.physics.montana.edu/max_millennium/ops/observing.shtml. If you have any questions or comments about this new observing plan, or its implementation, please contact Ryan Milligan <r.milligan (at) qub.ac.uk>. 2.
