No. 213, "The 1859 Space Weather Event Revisited," by Ed Cliver: assessing the greatest space-weather events over the centuries. See See http://sprg.ssl.berkeley.edu/~tohban/wiki/index.php/RHESSI_Science_Nuggets . Older Nuggets are also 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.

Using Fermi Solar Flare Data
by Dennis, Brian R. (GSFC-6710) 15 Nov '13

15 Nov '13

I am asking for your help in assessing the value of our Fermi Guest investigator project to make the Fermi GBM and LAT data readily available to the solar physics community. We are writing a follow-on proposal to continue this project, and it will be important to show how widely the Fermi solar observations are being used, and how useful the capabilities are that we are providing to access and analyze the data. Please let me know of any use you are making of Fermi X-ray and gamma-ray observations of solar flares. Are you using or are you planning to use any of the solar-specific access and analysis tools we have provided? Here is a short description of them: * Fermi solar flare page at http://hesperia.gsfc.nasa.gov/fermi_solar/ * Fermi GBM Flare List at http://hesperia.gsfc.nasa.gov/fermi/gbm/qlook/fermi_gbm_flare_list.txt * Quick-look count-rate light curves for both the Gamma-ray Burst Monitor (GBM) NaI and BGO detectors available on the RHESSI Browser at http://sprg.ssl.berkeley.edu/~tohban/browser/?show=grth1+qlpcr+gbmd+gbmo&da… * LAT quick-look time lines available on the RHESSI Browser coming soon. * Spectral analysis of GBM data in OSPEX * Spectral analysis of LAT data in OSPEX coming soon If you have been accessing and using Fermi data, even if it is just looking at the time lines on the RHESSI Browser, please drop me a line. Let me know how you access the data, how you have used them, and what you think of our web site and the ease of access and data analysis. Also, please include references to any use or mention of Fermi data in a presentation or publication. Thanks for your help, Brian Brian R. Dennis Solar Physics Laboratory, Code 671 Goddard Space Flight Center Greenbelt, MD 20771 301-286-7983 brian.r.dennis(a)nasa.gov

Second Announcement: 14th European Solar Physics Meeting (ESPM-14), Trinity College Dublin, Ireland, 8-12 September 2014
by D. Shaun Bloomfield 01 Nov '13

01 Nov '13

Dear Colleagues, This is the second announcement for the 14th European Solar Physics Meeting (ESPM-14) that will take place in Dublin, Ireland over 8-12 September 2014. The meeting will be hosted by Trinity College Dublin, which is centrally located in Dublin city. ESPMs are organized by the Board of the European Solar Physics Division (ESPD), a joint Division of the European Physical Society (EPS) and the European Astronomical Society (EAS). These meetings occur every 3 years with the purpose of bringing together researchers from Europe and beyond that are active in the theoretical and observational study of all solar phenomena. We are pleased to announce the following preliminary list of science session titles for ESPM-14: Session 1 - New and Upcoming Heliospheric Observational and Data Assimilation Facilities Session 2 - The Sun as a Whole: Large-Scale Flows, Magnetism, Magnetoconvection and the Solar Cycle Session 3 - Emergence and Evolution of Magnetic Flux in the Solar Atmosphere Session 4 - Chromospheric Dynamics Session 5 - Heating and Transient Activity of the Solar Corona: Waves, Flows, Reconnection and Jets Session 6 - Solar Eruptive Events: Instabilities, Flares and Coronal Mass Ejections Session 7 - Radio Emission and Particle Acceleration Session 8 - The Solar Wind and Space Weather Research Online registration and abstract submission will open in early spring 2014. The ESPM-14 Local and Scientific Organizing Committees are currently working to secure funding that will provide financial aid to a number of PhD students via partial travel and/or local support. Further details related to registration costs, abstract submission, accomodation, financial assistance and relevant deadlines will be circulated in a third announcement shortly after the New Year. The meeting website can be found at http://www.espm14.ie We look forward to welcoming you to Dublin. Best regards, ESPM-14 Scientific and Local Organizing Committees
