====== THEMIS Solar Telescope ====== The "Télescope Héliographique pour l’Étude du Magnétisme et des Instabilités Solaires" (THEMIS) of [[https://www.insu.cnrs.fr/en|CNRS-INSU]] is a 1-meter-class optical solar telescope, primarily dedicated to studying solar magnetism and the dynamical processes within the Sun’s atmosphere (such as sunspots and solar flares). THEMIS can also perform observation of near-Sun objects such as Mercury and comets. THEMIS is located at the [[https://www.iac.es/en/observatorios-de-canarias/teide-observatory | Teide Observatory]] of [[https://www.iac.es/en | IAC]], with a base office in La Laguna, in Tenerife, Canary Islands, Spain. /* ;#; 2025 campaign schedule ** ¡¡¡ Call for the [[observation:2025campaign | 2025 observing campaign]] is open !!! ** \\ Deadline for "French" and "International" time" : February 17th, 2025. ;#; */ ** New : ** ** [[science:results:IBISNov25 | First screw of the Italian IBIS 2.0 Spectro-imager @ THEMIS.]] ** \\ ** New : ** [[science:results:SeminIAC25 | Seminar on THEMIS at the Instituto de Astrofísica de Canarias, La Laguna (ES).]] \\ [[science:results:SeminLPP | October : Seminar on THEMIS at the Plasma Physics Laboratory, Paris (FR).]] \\ [[science:resources | Downloadable posters highlighting recent high-resolution observations of solar active regions by THEMIS]] \\ Click for information on: \ \ **[[admin:location| How to reach THEMIS locations]]** \ ; \ **[[admin:contacts| How to contact the THEMIS team]]**

\\ IBIS 2.0 is coming! \\ \\ During a preparatory visit at THEMIS, the INAF Italian team of the [[https://www.ibis20.inaf.it/| Interferometric BIdimensional Spectrometer - IBIS 2.0]] has started to assemble the first pieces of the optical bench of IBIS 2.0. An alternative beam path provided by THEMIS, located after its adaptive optics, will exit the THEMIS spectrograph hull and feed IBIS 2.0, which will be mounted vertically on THEMIS. The upgraded version of IBIS 2.0 shall be fully installed on the optical bench shown in the picture during the spring of 2026. IBIS 2.0 will be an outstanding synergic complement of THEMIS long slit spectrograph MTR2, enhancing THEMIS competitiveness in the 1-1.5m solar telescope category, providing new strong scientific capabilities to study the dynamics of the low solar atmosphere.
