We report on a NIR flare of the radio source NVSSJ020344+304238, cross identified with the high redshift quasar BZBJ0203+3042 (z=0.761) and tentatively with the Gamma-ray source 3FGLJ0203.6+3043. Following the report of the visible detection the source by the MASTER project (Atel#10985), We have observed the source in the NIR, finding that on January 6th,2018 (MJD 2458124.7406) its fluxes corresponded to J = 15.296 +/- 0.04, H = 14.743 +/- 0.03 and Ks = 13.200 +/- 0.06. The flux in Ks being 5.5 times brighter than the previously determined value by our team (Ks = 15.044 +/- 0.05 on MJD 2458084.8680) 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.
