European Solar Telescope

The EST design will strongly emphasise the use of a large number of visible and near-infrared instruments simultaneously, thereby improving photon efficiency and diagnostic capabilities relative to other existing or proposed ground-based or space-borne solar telescopes. In May 2011 EST was at the end of its conceptual design study. The EST is being developed by the European Association for Solar Telescopes (EAST), which was set up to ensure the continuation of solar physics within the European community. Its main goal is to develop, construct and operate the EST. The European Solar Telescope is often regarded as the counterpart of the American Daniel K. Inouye Solar Telescope which finished construction in November 2021.

The conceptual design study conducted by research institutions and industrial companies was finalized in May 2011. The study took 3 years, cost €7 million and was co-financed by the European Commission under the EU's Seventh Framework Programme for Research (FP7). The study estimates €150 million to design and construct the EST and projects about €6.5 million annually for its operation.

• Illustration — The member institutes of the European Association for Solar Telescopes originate from 15 different countries. The European Association for Solar Telescopes (EAST) is a consortium of 7 research institutions and 29 industrial partners from 15 European countries, that exists with the aim, among others, of undertaking the development of EST, to keep Europe in the frontier of Solar Physics in the world. As well as EAST intends to develop, construct and operate a next-generation large aperture European Solar Telescope (EST) in the Roque de los Muchachos Observatory, Canaries, Spain. • Institute — Location • IGAM — Institutsbereich Geophysik, Astrophysik und Meteorologie — Austria — Graz • HVO — Hvar Observatory — Croatia — Hvar • AIASCR — Institute of Atmospheric Physics AS CR|Astronomical Institute AS CR — Czech Republic — Ondrejov • THEMIS — THEMIS S.L., INSU-CNRS, CNR — France — Paris • KIS — Kiepenheuer-Institut für Sonnenphysik — Germany — Freiburg • HSPF — Hungarian Solar Physics Foundation — Hungary — Gyula • INAF — Istituto Nazionale di Astrofisica — Italy — Rome • UU — Utrecht University, Sterrenkundig Instituut — Netherlands — Utrecht • ITA — Institute for Theoretical Astrophysics — Norway — Oslo • IA UWr — Astronomical Institute of the Wroclaw University — Poland — Wroclaw • AISAS — Astronomical Institute of the Slovak, Academy of Sciences — Slovakia — Tatranská Lomnica • IAC — Instituto de Astrofísica de Canarias — Spain — La Laguna • SU — Institute for Solar Physics — Sweden — Stockholm • IRSOL — Istituto Ricerche Solari — Switzerland — Locarno • UCL-MSSL — University College London - MSSL — United Kingdom — London
