by Lucie Green 28 Feb '11

28 Feb '11

http://msslxr.mssl.ucl.ac.uk:8080/SolarB/eisnuggets.jsp UCL-MSSL is pleased to announce a new Hinode EIS science nugget on “Full Sun monochromatic images” by Ignacio Ugarte-Urra (George Mason University) and Harry Warren (Naval Research Laboratory). The nugget will be available from 1 March. Next month's nugget is entitled "An X-ray jet simultaneously seen by SUMER, EIS, XRT, and EUVI A & B" by Maria Madjarska of Armagh Observatory. EIS nuggets are published on the 1st of every month and we welcome contributions from the community. Please contact Lucie Green if you are interested.

RHESSI XI - registration deadline is in 4 days
by Eduard Kontar 17 Feb '11

17 Feb '11

Dear Colleagues, This is a gentle reminder that the registration deadline for 11-th RHESSI workshop is 17:00 UT, Monday 21st February. If you have not submitted an abstract/paid registration fees yet, please do so as soon as possible at the workshop homepage: http://www.astro.gla.ac.uk/rhessi11/ Kind regards Eduard ************************************************************** Location/dates/ timetable ------------------- The meeting will be held in the School of Physics and Astronomy, Kelvin Building, University of Glasgow [founded 1451 - past Professors include Alexander Wilson (Wilson Effect), James Watt, Lord Kelvin, and Peter Sweet. The welcome reception with drinks/snacks will be organised near the workshop venue on April 3, 2011 at 6pm. The workshop will start on Monday (April 4) at 9am and will be finished on Thursday (April 7) at 5 pm. The general timetable is available here: http://www.astro.gla.ac.uk/rhessi11/prog.php Registration/abstract submission ------------------------------- The workshop registration/abstract submission is open now. http://www.astro.gla.ac.uk/rhessi11/reg.php The registration fee (covering reception, workshop dinner and coffee breaks/refreshments) Standard fee 195 GBP Student fee 120 GBP Glasgow Travel and Accommodation -------------------------------- The city airport is served by several transatlantic carriers and several direct European connections while nearby Prestwick supports various transatlantic charter companies. There are fast and frequent direct air, rail, and coach services to London, Manchester and other UK destinations. Early April precedes the main holiday and conference season, so accommodation should be fairly readily available in all price ranges. A list of hotels and B&Bs within walking distance and booking information, plus local travel and tourism information is available at the webpage. http://www.astro.gla.ac.uk/rhessi11/travel.php http://www.astro.gla.ac.uk/rhessi11/acc.php Meeting Arrangements -------------------- RHESSI XI will continue the series of RHESSI workshops but it also marks 40 years since the publication of Prof. John Brown's thick-target model paper which has since been the standard approach to interpret solar flare hard X-ray spectra. The workshop will focus on topics/problems related to the understanding of energetic particles in solar flares. The workshop will have five groups covering a wide range of topics broadly related to thick-target model interpretation of solar flares. Up to three working group sessions will be run in parallel. The group topics have been designed with distinct agendas but also with some overlap to facilitate joint sessions. Considerable cross team flux, short of chaos, will be encouraged. All groups encourage contributions on theory, simulations, observations and RHESSI instrumental/software issue. We discourage contributions unrelated to the working group agendas. For details, see the webpage: http://www.astro.gla.ac.uk/rhessi11/wg.php Best regards, Eduard Kontar On behalf of the organisers Marina Battaglia, Nicolas Bian, John Brown, Gordon Emslie, Lyndsay Fletcher, Iain Hannah, Eduard Kontar, Alec MacKinnon, David Pontin (Dundee), Thomas Neukirch (St. Andrews)

FROM THE EDITOR ===================================================================== 1. FIRST X-CLASS FLARE OF CYCLE 24: DID YOU GET IT? --------------------------------------------------- > From Richard Canfield <canfield (at) physics.montana.edu> If you do not routinely receive the Max Millennium Message of the Day (MOTD), then subscribe now at http://solar.physics.montana.edu/max_millennium/mmlists.shtml. On February 13th, subscribers received a heads-up from Max Millennium Chief Observer (MM_CO) Bill Marquette, in the form of a MM Major Flare Watch message. Within half an hour of the issuance of that MOTD, the first of several major flares (M6.6) took place, followed about two days later by the first X-Class flare (X2.2) of Solar Cycle 24. During the period 2001-2010, about 75% of all X flares occurred during MM Major Flare Watches: see http://sprg.ssl.berkeley.edu/~tohban/wiki/index.php/Major_Flare_Watch_Evalu…. The current goal of the MM_COs is to call Major Flare Watches whenever there is a good chance for flares at GOES levels > M5 or so. If there is some way that the MOTD can be used or improved to enhance your flare observations, whether for a scheduled campaign or on a target-of-opportunity basis, contact me or any of the MM_COs: http://solar.physics.montana.edu/max_millennium/mm_co.shtml. 2.

No. 145: At Last, the EUV Spectrum, by Hugh Hudson. The main flare radiated energy is not in the EUV. http://sprg.ssl.berkeley.edu/~tohban/wiki/index.php/At_last,_the_EUV_Spectr… Older Nuggets are available at http://sprg.ssl.berkeley.edu/~tohban/wiki/index.php/RHESSI_Science_Nuggets (the new series), and at http://sprg.ssl.berkeley.edu/~tohban/nuggets/ (the original series). We publish these at roughly two-week intervals and welcome contributions, which should be at least loosely related to RHESSI science.
