THEMIS Solar Telescope

The THEMIS solar telescope (“Télescope Héliographique pour l’Étude du Magnétisme et des Instabilités Solaires”) of 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 Teide Observatory of IAC, with a base office in La Laguna, in Tenerife, Canary Islands, Spain.
