We report on the recent NIR brightening of the QSO CGRabSJ0211+1051 (z=0.20), cross identified with the Gamma-ray source 2FGLJ0211.2+1050 and the radio source NVSS J021113+105134. On February 16th, 2016 (MJD 2457434.65), we found the object with the following fluxes: J = 12.950 +/- 0.06, H = 12.042 +/- 0.02 and Ks = 11.275 +/- 0.05. In our previous observation on MJD 2457374.82 it had J = 13.937 +/- 0.04, H = 13.103 +/- 0.04 and Ks = 12.200 +/- 0.06. Hence, the object has had an increase in flux of about 1 magnitude in this rather short lapse. This object has undergone periods of enhanced activity in the past (see Atel#5570 and Atel#6778). 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.
