From Solar Jets to Inner-Heliospheric Switchbacks (JET2SB) From Solar Jets to Inner-Heliospheric Switchbacks (JET2SB) is a 42 month collaborative science project that started in October 2025. JET2SB is supported by the French Agence Nationale pour la Recherche (ANR) under the grant agreement n°ANR-25-CE31-7416. In the context of the Parker Solar Probe (NASA) and Solar Orbiter (ESA) space missions, JET2SB aims at better understanding the connection between the Sun and its heliosphere and i…

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.
