We report on the recent NIR flare of the Blazar BZBJ2244+4057 a high redshift blazar (z=1.171) associated with the Gamma-ray source 2FGLJ 2244.1+4059, On November 22nd, 2015 (JD 2457348.654), We determined the flux from this object to correspond to J = 13.414 +/- 0.04, H = 12.580 +/- 0.06 and Ks = 11.774 +/- 0.06. That is 1.3 mag brighter than the flux value measured by our team previously. On JD245732976, we determined a flux corresponding to H = 13.871 +/- 0.06. Henceforth, this blazar has had a significant increase in flux, in the H band, by a factor of about 4 in this rather short lapse. This object is included in our NIR monitoring program of Gamma Ray bright AGNs and has shown multiwavelength flaring activity in the past (see ATEL #5690, #6402 #7126). Our observations are 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.
