We report that BL LAC cross identified with the Fermi LAT Gamma Ray source 2FGLJ2202.8+4216 is undergoing a significant NIR brigthening, on October 16th,2013 JD2456581.771019 we determined the flux in the H band to corresponde to H = 10.396 +/- 0.05.
That is to be compared with the flux determined for this object on JD 2456282.665081 when the flux was H = 11.979 +/- 0.07. Observations were carried out with the 2.1m telescope of the Guillermo Haro Observatory operated by the National Institute for Astrophysics, Optics and Electronics (Mexico), equipped with the instrument CANICA a NIR camera. We strongly encourage further multi-wavelength coverage.
