We report on the new, recent NIR Flare of the intermediate redshift blazar BZQJ1246-2547 (z=0.633), also known as HB89 1244-255, associated with the gamma-ray source 2FGL1246.7-2546. Our NIR photometry for this source on April 16th,2016 (JD2457494.7381), the object brightness corresponded to J = 14.081 +/- 0.04, H = 13.359 +/- 0.05 and Ks = 12.422 +/- 0.05. These values are about 0.6 magnitudes brighter than our previous photometry, obtained on JD2457465.7, for this field. The object is brightest since we started monitoring it on JD 2454857. The object has undergone flaring
activity in the past (see Atel#5713). Our observations are 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 multiwavelength coverage.
