We have observed a recent NIR brightening of the quasar BZB J2005+7752 (z=0.342), cross identified with the gamma ray source 1FGL J2006.0+7751. On December 20th,2012, epoch JD2456281.608634, we determined the flux in the H band to be 12.782+/- 0.05. That is 1.8 magnitudes brighter than the flux determined by the 2mass survey and presently is brightest since the epoch JD2455368.93, when we started monitoring this object at NIR wavelengths. 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 encourage further multi-wavelength coverage.
