The “Télescope Héliographique pour l’Étude du Magnétisme et des Instabilités Solaires” (THEMIS) 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. New ¡¡¡ 2026 observing campaign schedule !!!

To celebrate the 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 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. |
