We report on a NIR Flare of the high redshift QSO BZQJ0348-2749 (z=0.991) cross-identified with the Gamma-ray source 2FGLJ0348.6-2750. On December 19th,2018 (MJD 24578471.7858), we found the source with NIR fluxes J =13.963 +/- 0.05, H = 13.043 +/- 0.05 and Ks = 12.183 +/- 0.05. While on MJD 2458448.799 the flux in the H band corresponded to H = 14.561 +/- 0.04. Hence, the source has increased its flux by a factor of 4. in this short lapse. The source is brightest since the time we started monitoring it (MJD 2455459.97), when the flux in the H band was 15.393 +/- 0.15 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.
