On the 24th of September Dr. Charlotte Géhan from UPorto held a first virtual seminar and discussion in front of 100 students at the institute of Space Astrophysics UPSaclay. The pilot practice was held in the initiation course by Prof. Hervé Dole and was a great success, showing that guest lectures can easily be adapted and implemented on all levels. The lecture has been recorded and a video is in preparation.
