We report on the recent observation that revealed a NIR brightening of the low redshift quasar CGRaBSJ0211+1051 (z=0.20), cross identified with the radio source NVSS J021113+105134 and the
Gamma-ray source 2FGLJ0211.2+1050. On December 1st,2014 (JD 2456992.760509), its flux in the H band corresponded to the magnitude H = 11.274 +/- 0.02. This value is to be compared with our previous photometry for this object H = 11.810+/- 0.06, on JD2456980.892627. Hence, this object has increased its brightness by 60% in the last 12 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.
