Because of its relatively high redshift (z=2.172), this blazar shows a prominent accretion disc bump peaking in the ultra-violet band, which makes this source an excellent candidate to investigate not only the jet emission but also the non thermal one. We investigated its spectral energy distribution by means of almost simultaneous observations covering the cm, mm, near-infrared, optical, ultra-violet, X-ray and gamma-ray energy bands obtained by the GASP-WEBT Consortium, Swift, and AGILE satellites. We present the spectral energy distribution of the gamma-ray flare whose energy coverage is more dense, modelling it by means of a one-zone leptonic model.ELETTRONICOenMultimediahttps://www.cosmos.esa.int/web/xmm-newton/2017-symposium2017xru..conf..337VFIS/05 - ASTRONOMIA E ASTROFISICAERC sectors::Physical Sciences and Engineering::PE9 Universe sciences: astro-physics/chemistry/biology; solar systems; stellar, galactic and extragalactic astronomy, planetary systems, cosmology, space science, instrumentation
