Top panel: interpretation of the γ-ray emission observed by Fermi-LAT (shaded region) and MAGIC (full circles) in the framework of the interaction of the relativistic electrons in a blob with the radiation field of a star that has entered the jet (magenta model line). The absorption in the Extragalactic Background Light is taken into account according to the Domínguez et al. (2011) model. Bottom panel: MAGIC light curve above 200 GeV. The dashed vertical lines are the time range from which the SED (top panel) is computed.
