-The THEMIS solar telescope ("Télescope Héliographique pour l’Étude du Magnétisme et des Instabilités Solaires") 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 observations of the east sunspot group of the active region NOAA 13981 on February 6th 2025. The left image is a Knox-Thompson reconstructed from red continuum broadband camera. The right panels are intensity maps reconstructed from spectral observations by the MTR2 spectrograph observing the H_\alpha absorption line. Theses maps are reconstructed from a scan by the telescope of the active region. While these intensity images have a lower spatial resolution, they provide a wealth of spectroscopic information. The region was observed during a flare, as can be noted by the typical ribbon-shape emission in the H_\alpha line centre. This emission is absent from the continuum emission, indicating a chromospheric emission phenomena. Meanwhile, the red wing maps (H_\alpha+1Å and H_\alpha+1Å) display dark absorbing material above the location of the flare ribbons, signature of down-flowing dense material, a phenomena nicknamed "coronal rain".
+During a preparatory visit at THEMIS, the INAF Italian team of the [[https://www.ibis20.inaf.it/| Interferometric BIdimensional Spectrometer - IBIS 2.0]] has started to assemble the first pieces of the optical bench of IBIS 2.0. An alternative beam path provided by THEMIS, located after its adaptive optics, will exit the THEMIS spectrograph hull and feed IBIS 2.0, which will be mounted vertically on THEMIS. The upgraded version of IBIS 2.0 shall be fully installed on the optical bench shown in the picture during the spring of 2026. 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.
