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
