Last call for abstracts for the upcoming SPHERE workshop (June 20–23)
by Shih, Albert Y. (GSFC-6710) 23 May '23

23 May '23

Tomorrow (May 24) is the deadline for submitting abstracts for the second Solar Physics High Energy Research (SPHERE) Workshop! The SPHERE workshop (https://sphere.boulder.swri.edu) will be held 20–23 June 2023 at the University of Maryland, College Park. Early-career researchers and students will be granted requests for oral presentations. As the successor to the RHESSI workshop series, the SPHERE workshop series aims to foster the development of an integrated and unified understanding of high-energy processes on the Sun by bringing together experts in X-ray/radio/EUV observations, theory, and modeling. The three broad science topics are: * Energy storage and release – e.g., reconnection, eruption initiation * Energy conversion – e.g., particle acceleration (electrons and ions) and plasma heating * Energy transport – probing high energy solar phenomena using remote sensing and in situ diagnostics Registration for the workshop will continue to be open until June 13, but be aware that the special hotel rates are available for only two more weeks. We look forward to seeing you in College Park! – Albert Shih (albert.y.shih(a)nasa.gov<mailto:albert.y.shih@nasa.gov>), on behalf of the organizing committee

FROM THE EDITOR ===================================================================== 0. MSU NETWORK OUTAGE (2023/04/20 - 2023/05/03) ----------------------------------------------- The Montana State University IT team had shutdown the whole campus network to handle a large cyberattack on 20th, April (in MDT). Since then, e-mail communication through our server and accesses to our web server had been unavailable. Today, finally, the communication between our e-mail/web server and outside of the compus has been open again. Our e-print page should work as before. Please let me know, if you find anything wrong. If you posted messages to our mailing lists (mmscience, rhessi_data_analysis) and did not confirm their distribution, please post them again. It should go through now. 1.
