We report on the recent NIR flare of the intermediate redshift QSO (z=0.54) BZQJ0713+1935, cross correlated with the Gamma-ray source 2FGLJ0714.0+1933 and the radio source MG2J071354+1934. On May 9th,2019 MJD(2458612.6329), we found the source with NIR fluxes corresponding to J = 14.81 +/- 0.04, H = 13.94 +/- 0.03 and Ks = 13.41 +/- 0.04. While on MJD 2458604.6759 the flux in the H band corresponded to H = 15.602 +/- 0.04. Hence, the source has increased its flux by a factor of 4.7 in this short lapse (8 days). The source has shown flaring activity in the past (see AtTel #10184), and is brightest since the time we started monitoring it on MJD2455182. 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.
