Solar Physics High Energy Research (SPHERE) Workshop — 11–15 July 2022 — Boulder, CO, USA + Windisch, CH + online
by Amir Caspi 15 May '22

15 May '22

Dear colleagues, The Solar Physics High Energy Research (SPHERE) Workshop -- formerly known as the RHESSI workshop, and now motivated by SolO/STIX, MinXSS, EOVSA, and many other current and upcoming missions -- will be held 11–15 July 2022. The workshop will be a hybrid format with online access and two in-person locations: Southwest Research Institute (SwRI) in Boulder, Colorado, USA and Fachhochschule Nordwestschweiz (FHNW) in Windisch, Switzerland. The workshop agenda will include plenary topical sessions, held jointly between all locations, featuring invited talks and facilitated, open discussions on targeted science questions. This interactive format is intended to foster both broader and deeper collaboration and understanding amongst our community, to propel progress and enhance success by breaking down silos both within the high-energy solar physics and among solar and space physics in general. Additional independent morning (EU) and afternoon (US) sessions will feature tutorials, posters, early-career talks, and open collaboration. Registration is required, and U.S. hotel accommodations (for the contract hotel) will be handled through the registration form. Abstracts for posters and early-career presentations, and suggestions for open topical discussions, will be solicited soon. The workshop website at https://sphere.boulder.swri.edu is operational with preliminary information, including travel information, and will be updated soon with registration information and deadlines. We hope to see you soon in Boulder, Windisch, or online! – Amir Caspi & Säm Krucker, on behalf of the organizing committee

TESS Topical Session on the Millimeter Chromosphere
by Kobelski, Adam R. (MSFC-ST13) 14 Apr '22

14 Apr '22

Hi All, In case you hadn’t seen it and were still debating where to submit your abstract, I wanted to remind you about session 23 before the TESS abstract deadline tomorrow: “Investigating the Solar Chromosphere at Millimeter Wavelengths”. Meeting website: https://aas.org/meetings/tess2022 If you have any science results utilizing millimeter wavelength observations, or that could benefit from millimeter wavelength observations, we encourage you to submit an abstract. Thank you, and we hope to see you in Bellevue! Adam, on behalf of the ALMA Solar Development Team 23. Title: Investigating the Solar Chromosphere at Millimeter Wavelengths Conveners: Adam Kobelski (NASA Marshall Space Flight Center), Gianna Cauzzi (National Solar Observatory) One of the most notable new developments in the study of the solar chromosphere is the ability to obtain high resolution observations of the Sun at millimeter wavelengths using the Atacama Large Millimeter Array (ALMA). This interferometric imaging array of 64 dishes, located at an altitude of 5000 meters in Chile, is currently able to observe the Sun at frequencies from 90 GHz to 370 GHz (~ 0.85 – 3.0 mm wavelengths), achieving spatial resolutions as high as 0.6”, with 1 s cadence. The millimeter continuum is emitted by electrons over much of the range from the temperature minimum to the transition region, and provides a direct measure of the local temperature. Thus, ALMA data provide important new diagnostics for studying the spatio-temporal structure and dynamics of the solar chromosphere. Over the past few years, the community has made significant progress in the processing and interpretation of this interferometric data. and numerous studies have used these data to probe various features and processes in the solar atmosphere. Within this session, we aim to introduce the community to both novel science results obtained by this new facility and to highlight future scientific opportunities enabled by ALMA, especially those in coordination with ground and spaced based instruments. We invite contributions from previous users of ALMA about their results, but also presentations of studies of the solar chromosphere that would potentially benefit from the additional temperature and magnetic field diagnostics from these millimeter observations. Two featured talks will provide a broad overview of solar ALMA science, including the potential for observations of solar activity and flares, and provide guidance for potential new users of the facility, with the goal of inspiring a broader participation in this exciting science.

TESS session 16: next-gen missions -- call for abstracts
by Amir Caspi 13 Apr '22

13 Apr '22

Hi all, It's a bit last-minute, but I wanted to ensure that everyone knew about our TESS session #16, "High-Energy Solar Investigations Through Next-Generation Remote Sensing: Spectroscopy, Imaging, and Beyond." This is the next installment in our now long-running successful series of AGU sessions for next-gen missions, instruments, technology, and science studying high-energy processes on the Sun. Please consider submitting an abstract to the session! We welcome a broad range of topics, and especially encourage decadal concepts and long-term outlook. Abstracts are due this Friday, April 15. The session description is below, for your reference. Abstracts can be submitted at the following URL: https://submissions.mirasmart.com/TESS2022/Splash.aspx Looking forward to seeing you at TESS, in session 16! =) --- Amir, on behalf of the conveners 16. Title: High-Energy Solar Investigations Through Next-Generation Remote Sensing: Spectroscopy, Imaging, and Beyond Conveners: Amir Caspi (SwRI), Lindsay Glesener (UMN), Tom Woods (CU/LASP) Description: Energetic phenomena on the Sun, including impulsively-driven eruptions (flares and coronal mass ejections) and more gradual coronal heating and solar wind outflows, provide crucial insight into unique regimes of plasma physics and astrophysical processes, and are also the primary drivers of space weather. Physical processes within these phenomena, including particle acceleration and plasma heating, emit signatures across the electromagnetic spectrum, from Xrays/gamma-rays, through UV/EUV, to infrared and radio. Spectral and imaging observations of these emissions provide critical diagnostics into the macro- and microphysics underlying these processes. The X-ray and EUV emissions are also significantly geoeffective, contributing to societally-important dynamical effects in Earth’s upper atmosphere and ionosphere on a variety of timescales. Recent measurements from numerous solar observatories including RHESSI; SDO; SolO; MinXSS; SphinX; Chandrayaan-2; the FOXSI, MaGIXS, Hi-C, EUNIS, and EVE rockets; the GRIPS balloon; EOVSA; and many others – and from opportunistic observations by non-solar observatories such as NuSTAR, Fermi, ALMA, and VLA – have significantly advanced our understanding of these phenomena and their driving processes. They have also shown the pressing need for increasingly advanced high-resolution, high-sensitivity measurements across the entire spectrum, including polarimetry and especially imaging spectroscopy, to gain further insight into these high-energy processes and the solar magnetic field that powers them. This session invites presentations covering new instrumentation, enabling technology, missions, and concepts for next-generation solar remote sensing -- including spectroscopy, imaging, and beyond -- aimed at studying high-energy (hot and non-thermal) aspects of the Sun, as well as the solar magnetic field. Presentations are also invited on the science enabled by such new observations, including space weather-related science and impacts to Earth’s atmosphere and ionosphere. Recognizing the 2023-2032 Heliophysics Decadal Survey currently under way and the community-led Heliophysics 2050 vision, we also encourage presentations that include longer-term future outlooks and both intra- and inter-disciplinary integration of solar and heliospheric physics, space physics, and other relevant fields.
