====== 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:2026campaign#campaign_schedule | 2026 observing campaign schedule]] !!! ** \\ \\ ;#; /* ;#; ** ¡¡¡ Call for the [[observation:2026campaign | 2026 observing campaign]] is open !!! ** \\ Deadline for "French" and "International" time" : February 13th, 2026. \\ Deadline for "Spanish" time" : January 21st, 2026. ;#; */ [[science:results:TenerifeAcceuilVisit2026 | April : Public visit of the THEMIS facility to celebrate its 1st-light 30th anniversary.]] \\ [[science:results:Solo2026 | March : Participation of THEMIS at the "10th Solar Orbiter Scientific Workshop" in Berlin (DE).]] \\ February : The THEMIS team supports the call to French research personnel to [[https://atst.osups.universite-paris-saclay.fr/est-white-paper/| co-sign the white paper in support to the European Solar Telescope (EST) project]] \\ /*[[https://atst.osups.universite-paris-saclay.fr/est-white-paper/ | February : The THEMIS team supports the call to French research personnel to co-sign the « White paper on the relevance of the European Solar Telescope (EST) for the French heliophysics community »]] */ [[science:results:IBISNov25 | November : First screw of the Italian IBIS 2.0 Spectro-imager @ THEMIS.]] \\ Click for information on: \ \ **[[admin:location| How to reach THEMIS locations]]** \ ; \ **[[admin:contacts| How to contact the THEMIS team]]** /* STANDARD PIC */ /* */ /* WINTER PIC */ /* SPRING PIC */ /* */ /* NIGHT PIC */ /* */ === 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:2026campaign | 2026 observing campaign]] \\ [[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:gallery| THEMIS observations and media galleries]] \\ [[science:resources | Media resources (Posters, logos, ...)]] == THEMIS image of the month: May 2026 == \\ \\ To celebrate the [[science:imofmonth#April 2026| 30th anniversary of its first light]], the whole team of FSLAC and THEMIS organised a public visit of the THEMIS facility for the members of the [[https://www.tenerifeaccueil.es/ | Tenerife acceuil]] association, the cultural association that aims to bond the French speaking and Francophile community in Tenerife. We received about 100 persons, with one third of young public. This was the occasion to show the Sun, to present a contemporary research facility, to speak about current solar physics and space weather research, to highlight THEMIS science and technique, as well as to speak about more broadly about astronomy, about the Teide Observatory and the IAC, as well as to focus on the violent Universe thanks to the high energy FSLAC team. FSLAC & THEMIS wish to thanks the Tenerife acceuil board, the IAC staff of the Teide Observatory and the communication department, and the French civil service volunteer who all helped to make this a safe and pleasant day.
