We report on the recent NIR flare of BZBJ2250+3824 (B32247+381) a low redshift blazar (z=0.1187), associated with the Gamma-ray source 2FGLJ2250.0+3825, On November 22nd, 2015 (JD 2457348.63), We determined the flux from this object to correspond to Ks = 12.117 +/- 0.04. That is 0.8 mag brighter than the flux value measured by our team previously. On JD2457327.80, we determined a flux corresponding to Ks = 12.971 =/- 0.04. Henceforth, this QSO has had a significant increase in flux, in the Ks band, by a factor of about 2 in this rather short lapse. This object is included in the sample of our NIR monitoring program of Gamma Ray bright AGNs. 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.
