We report on the recent NIR flare of BZQJ1849+6705 (B31726+455) an intermediate redshift blazar (z=0.657) also known as CGRaBS J1849+6705, associated with the Gamma-ray source 2FGLJ 1849.4+6706, On November 6th, 2015 (JD 2453332.6402), We determined the flux from this object to correspond to J = 14.981 +/- 0.03, H = 14.144 +/- 0.05 and Ks = 13.335 +/- 0.05. That is about 1.6 mag brighter than the flux value measured by our team previously. On JD2457299.67, we determined a flux corresponding to H = 15.827 +/- 0.03. Henceforth, this QSO has had a significant increase in flux, in the H band, by a factor of about 5 in this rather short lapse. This object is included in our NIR monitoring program of Gamma Ray bright AGNs and has shown flaring activity in the past (see ATEL#6623). Our observations were carried out with the 2.1m telescope of the Guillermo Haro Observatory of the National Institute for Astrophysics, Optics and Electronics (Mexico), equipped with the instrument CANICA a NIR camera. We encourage further multi wavelength coverage of this object.
