S5 0716+714 is a well known BL Lac object, and one of the brightest and
most active blazars. The discovery in the Very High Energy band (VHE, E
> 100 GeV) by MAGIC happened in 2008. In January 2015, the source
went through the brightest optical state ever observed, triggering MAGIC
follow-up and a VHE detection with ∼ 13σ significance (ATel ♯6999 ).
Rich multiwavelength coverage of the flare allowed us to construct the
broad-band spectral energy distribution of S5 0716+714 during its
brightest outburst. In this work, we will present the preliminary
analysis of MAGIC and Fermi-LAT data of the flaring activity in
January and February 2015 for the HE (0.1 < HE < 300 GeV) and VHE
band, together with radio (Metsähovi, OVRO, VLBA, Effelsberg),
sub-millimeter (SMA), optical (Tuorla, Perkins, Steward, AZT-8+ST7,
LX-200, Kanata), X-ray and UV (Swift-XRT and UVOT), in the same
time-window and discuss the time variability of the multiwavelength
light curves during this impressive outburst.
