====== 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. /* ;#; ** ¡¡¡ 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. ;#; */ February : The THEMIS team supports the call to French research personnel to co-sign the white paper in support to the European Solar Telescope (EST) project (click here) /*[[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:OFRAMEdays2026 | February : Participation of THEMIS at the "OFRAME space weather days 2026" conference in Grenoble (FR).]] \\ [[science:results:Jorgearrival | January : One year visit at THEMIS of PhD student Jorge Romero Castañeda (LPP) in the context of the ANR JET2SB project.]] \\ [[science:results:KISmeeting | January : Presentation of THEMIS and IBIS at the "Methods and techniques for high-resolution spectro-polarimetry" conference in Freiburg (GER).]] \\ ** [[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: February 2026 == THEMIS cable reel \\ \\ A summary figure of THEMIS level 1 [[observation:data | data products]]. These are the datasets that are directly generated during an observation with THEMIS. The full Sun and slitjaw images are context images that are mainly used to have basic information of the solar condition on the Sun and the location of the high resolution observations. They are not really meant for scientific use, as equivalent data of a better quality can be obtained by other instruments. The main scientific data are the [[observation:data#Broadband images (BBI)| broadband images]] to study the dynamics of the solar photosphere at high-cadence and high spatial resolution, and the [[observation:data#Spectral images]] from which physical properties such as composition, density, temperature, velocities and magnetic field of the emitting solar plasma can be derived.
