Our friend and colleague Jean-Claude Vial is approaching the end of his Emeritus status, and he will leave the IAS in mid-2020. It is a major milestone for Jean-Claude, but also for the IAS and the international solar physics community. We wish to mark the occasion with a scientific colloquium covering the numerous topics to which Jean-Claude has dedicated his contributions.

Due to the Covid-19 pandemic, we regret to inform you that the colloquium entitled “Cool material in the solar corona at the time of Solar Orbiter” organized by the Institut d’Astrophysique Spatiale is cancelled.
