We report on a large NIR flare of the intermediate redshift blazar GB6 J1604+5714 (z=0.72) cross identified with the Gamma-ray source 2FGL1604.6+5710. On September 21st, 2016 (JD 2457652.7), we found the source to have a flux in the H band corresponding to H = 13.841 +/- 0,02, that is 2.4 magnitudes brighter than the lowest flux value H = 16.261 +/- 0.03 observed by our team on JD 2457290 as part of a monitoring campaign of blazars with detected Gamma-ray fluxes. The source was known by its activity previously reported in Atels,#4174, #4184, #4190 and #4991. Observations were 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 strongly encourage further multi wavelength coverage of this interesting object.
