A $\\gamma$-ray flare was observed in January 24, when the flux increased up to $(2.22\\pm0.38)\\times10^{-6}\\;{\\rm photon\\:cm^{-2}\\:s^{-1}}$ with the flux-doubling time scale being as short as $\\sim1.44$ days. The spectral analysis shows that from April 13 to April 28, 2015 the MeV-to-GeV photon index has hardened and changes in the range of $\\Gamma=(1.73-1.79)$ for most of the time.
