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

RHESSI re-entering the atmosphere very soon
by Shih, Albert Y. (GSFC-6710) 18 Apr '23

18 Apr '23

To RHESSI fans: RHESSI made 16 years of X-ray and gamma-ray observations before the mission ended in 2018 due to loss of communications. Although the spacecraft has continued to orbit the Earth since then, it is expected to finally re-enter the atmosphere very soon and burn up, possibly as soon as tomorrow! Here is NASA's press release: https://www.nasa.gov/feature/nasa-retired-solar-energy-imager-spacecraft-to… Pascal Saint-Hilaire and Hugh Hudson wrote a RHESSI nugget on the re-entry, including plots of the ground path underneath RHESSI for the next couple of days. With luck, you may be able to catch a glimpse of RHESSI as it burns up, while some parts of the observatory - notably the tungsten grids - may even survive re-entry. https://sprg.ssl.berkeley.edu/~tohban/wiki/index.php/RHESSI%27s_Re-entry I encourage you all to commemorate and celebrate RHESSI's long mission, which can include analyzing some portion of RHESSI's gigantic data set. I also recommend that you register for the upcoming SPHERE workshop (June 20-23), which builds off of the legacy of RHESSI: https://sphere.boulder.swri.edu/ Thanks! Albert Y. Shih RHESSI Deputy Mission Scientist

Please note: The performance of HXI/ASO-S in orbit looks excellent! Welcome you to register before April 5. Weiqun MEETING: The 4th ASO-S Meeting (Online) -- Tutorials on ASO-S Data The Advanced Space-based Solar Observatory (ASO-S) was launched on October 9, 2022. After six-month of commissioning phase, the ASO-S will release the data to the public. In order to facilitate use and analysis of ASO-S data by the broader community, the 4th ASO-S Meeting will be held online. The meeting consists of two sessions, i.e., China-America Session (April 10-11, 2023, America, EST; April 11-12, 2023, China, CST) and China-Europe Session (April 11-12, 2023, UTC/CST). There will be lectures and hands-on sessions. The lectures include introduction on ASO-S related topics and tutorials on data access and analysis. More information on attending the meeting will be obtained after the registration. Registration date: from March 15 to April 5, 2023. For more detailed information, please visit the meeting website: http://aso-s.pmo.ac.cn/english/science/meeting/meeting-202304.jsp
