THEMIS Solar Telescope
|
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.

THEMIS image of the month
IBIS 2.0 is at THEMIS ! In early June, about 800 kg of the Interferometric BIdimensional Spectrometer - IBIS 2.0, most of its scientific instrumentation and careful packaging has been received at the THEMIS telescope. Since then a dedicated visiting team from different sites of the Italian National Institute for Astrophysics (INAF), from Rome, Merate & Trieste, with some help of the THEMIS team, has been hard working in meticulously installing and starting to align all the pieces of this puzzle of optical instrumentation. In the month of June IBIS 2.0 has been slowly but meticulously assembled. IBIS 2.0 will be an outstanding synergic complement of THEMIS long slit spectrograph MTR2, enhancing THEMIS competitiveness in the 1-1.5m solar telescope category, providing new strong scientific capabilities to study the dynamics of the low solar atmosphere.
