The spectral energy distribution of 3C 279 on January 2009: MAGIC (taken in the period 21–31 January, red arrows: deabsorbed, cyan arrows: observed), LAT (averaged over the same period, red pentagons), XRT and UVOT (February 1, 2009 red squares) and KVA (January 25, 2009 red filled circle). The SED is modeled assuming the emission region inside the BLR. The historical data as in Fig. 8. The dashed line correspond to blackbody radiation from the IR torus (red).
