After a low state since 2002 comma bright outbursts in 2016 were surrounded by intermediate activity openPar2015-2018closePar. Past observations have revealed a peak-shift towards higher energies hinting an EHBL-like nature comma fast intranight and longterm variability as well as complex correlation patterns between wavebands. These features challenge a simple one-zone synchrotron self-Compton model. We request MAGIC observations coordinated with simultaneous multi- wavelength observations spanning a wide energy range comma to understand the evolution of the broadband spectrum comma compare different flux states comma characterize variability patterns comma study inter-band correlations and investigate the potential of the source as astrophysical neutrino emitter.
