We report on the recent NIR flare of the high redshift QSO (z=1.15) BZUJ1048+7143 also known as CGRaBSJ1048+7143, cross correlated with the radio source S51044+71 and the Gamma-ray source 2FGLJ1048.3+7144.On January 11th,2017 MJD(2457764.9797), we found the source with NIR fluxes corresponding to J = 13.900 +/- 0.05, H = 12.975 +/- 0.03 and Ks = 12.214 +/- 0.05. While, on MJD 2457498 the flux in the H band corresponded to H = 14.252 +/- 0.03. Hence, the source has tripled its flux in this 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.
