We report on the recent NIR flare of the high redshift QSO (z=0.94) PKS0235+164 also known as CGRaBSJ0238+1636, cross correlated with the Gamma-ray source 2FGLJ0238.7+1637.On FEbruary 3rd,2017 MJD(2457787.6717, we found the source with NIR fluxes corresponding to J = 14.867+/- 0.04, H = 13.795 +/- 0.03 and Ks = 12.947 +/- 0.05. While, on MJD 2457772.7 the flux in the H band corresponded to H = 14.561 +/- 0.03. Hence, the source has doubled its flux in this 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 encourage further multi wavelength coverage.
