We report on a NIR flare of the high redshift QSO B2 2234+28A (z=0.795), also known as CGRaBSJ2236+2828 associated with the gamma-ray source 2FGL2236.4+2828. Our most recent NIR photometry for this source shows that on January 12th,2016 (JD2457399.5555), the object brightness corresponded to H = 14.778 +/- 0.04. In our previous observation in this band (MJD2457346.7774) this object had H = 16.431 +/- 0.04. Hence, the object has increased its luminosity by a factor of about 6 in this rather short lapse. 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.
