We report on a recent NIR flare of BL Lac, associated with the Gamma ray source 2FGLJ2202.8+4216 (z = 0.0686). On October 2nd,2014 (JD, 2456932.786) we obtained NIR photometry for this object and found it with enhanced fluxes, corresponding to: J = 11.334 +/- 0.04, H = 10.473 +/- 0.03 and Ks = 9.657 +/- 0.04. Our previous photometry for this object on JD2456893 yielded fainter fluxes by a factor of 2.2. The present flare has reached a flux levels comparable to the brightest ones observed in the past in this object. Our 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 multiwavelength coverage.
