Institut de recherche sur les lois fondamentales de l'Univers

We will review the relevance of historical observations for current astrophysical problems, in particular for the  reconstruction of solar activity in the 17th century Maunder Minimium and the pre-telescopic time - as well as the study of historical supernovae in our Galaxy. Among other observations, we will discuss the strong 14-C variation around AD 775 detected in trees around the world and discuss possible causes like a nearby supernova,  a Galactic gamma-ray burst, a solar super-flare, etc.
