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 December 22nd, 2024 (JD 2460666.6884), We determined the flux from this object to correspond to H = 14.66 +/- 0.04. That is 12.6 mag brighter than the flux value measured by our team previously. On JD2460194.7872, we determined a flux corresponding to H = 17.26 +/- 0.04. Henceforth, this object has had a significant increase in flux, in the H band, by a factor of about 11 in this lapse. By JD2460680.664 the source had fainted to a flux level corresponding to H = 16.34 +/- 0.04 . 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, #8318). 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.
