We report on a significant NIR brightening of the QSO BZQJ2012+4628, associated with the gamma-ray source 1FGL2012.2+4629. Our most recent NIR photometry for this source shows that on June 11th,2016 (JD2457550.942), the object brightness corresponded to J = 13.790 +/- 0.05, H = 12.725+/- 0.05 and Ks = 12.032 +/- 0.06. The NIR fluxes in the JHK bands has increased, since our previously observed fluxes were: J = 14.958 +/- 0.05, H = 13.888 +/- 0.05 and Ks = 12.885 +/- 0.05, on JD2457373.6. Hence, the object has increased its luminosity by a factor of about 2 in this lapse. The object is brightest since the time we started monitoring it on MJD 2456464.9. Our observations are 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.
