We report on the recent observation that revealed a NIR brightening of the quasar CGRaBSJ0211+1051 cross identified with the Gamma-ray source 2FGLJ0211.2+1050. On October 28th,2013 (JD 2456593.877674), its flux in the H band corresponded to the magnitude H = 11.449 +/- 0.01. This value is to be compared with our previous photometry for this object H = 11.776 +/- 0.04, on JD2456551.833032. Hence, this object has increased its brightness by 30% in the last 40 days. 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 multi-wavelength coverage.
