====== 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. ;#; New: ** [[observation:2025campaign#2025 campaign schedule | Preliminary schedule of 2025 observing campaign]] ** \\ ;#; /* ;#; 2025 campaign schedule ** ¡¡¡ Call for the [[observation:2025campaign | 2025 observing campaign]] is open !!! ** \\ Deadline for "French" and "International" time" : February 17th, 2025. ;#; */ Click for information on: \ \ **[[admin:location| How to reach THEMIS locations]]** \ ; \ **[[admin:contacts| How to contact the THEMIS team]]** /* */ === Overview of telescope status === \\ [[http://themis.iac.es/wdata/Webcam/webcam.jpg | THEMIS from VTT webcam]] \\ [[http://themis.iac.es/wdata/Webcam/Domecam.jpg | Webcam of THEMIS Dome]] \\ Latest [[https://view.eumetsat.int/productviewer?v=default | EUMETSAT]] RGB image \\ [[observation:weather | THEMIS weather page]] \\ Last image from \\ THEMIS full Sun guider ---- === The THEMIS telescope and its science === **[[technical|Technical & scientific information about THEMIS]]** \\ [[science:objectives|THEMIS scientific objectives]] \\ [[admin|THEMIS administrative structures]] === Observing with THEMIS === **[[observation| Information for research scientists wishing to observe with THEMIS]]** \\ [[observation:weather | Weather at THEMIS location and weather forecast]] \\ [[observation:data| THEMIS data products & data access]] === THEMIS Scientific research & results === **[[science| Scientific research with THEMIS]]** \\ [[science:results| THEMIS scientific highlights and news]] \\ [[science:results:gallery| THEMIS observations and media galleries]] == THEMIS image of the month: April 2025 == 2022-2025 THEMIS sunspot best-of \\ A selection of THEMIS sunspot observations obtained between 2022 and 2025 with the [[technical:description#broadband_imaging_bbi_filter_camera | BroadBand Imaging Camera]].
