  The first one started in 2012 July 16 (MJD 56124) and the second one in 2013
April 9 (MJD 56391). The multiwavelength data analysis shows that the
$\gamma$-ray flare observed in 2012 was not detected in the hard-X ray bands.
This result is usually interpreted as an "orphan" flare. In 2013, the analysis
of the multiwavelength light curves shows that there are two very bright states
detected in the optical R-band. The first one in 2013 April 9 (R =11.74 $\pm$
0.04) and the second one in May 12 (R =11.62 $\pm$ 0.04). Also, high activity
states were detected in the soft and hard X-rays. A discrete correlation
function analysis of this last flare shows a strong correlation between the GeV
$\gamma$-rays and the optical/hard-X ray emission. These results are discussed
in terms of the more adequate standard scenarios that could explain the
multiwavelength variations displayed by this blazar.
