We report on recent NIR Flaring event of the high redshift Blazar [HB89] 0805-077 (z=1.837) also known as CGRaBS J0898-751, associated with the Gamma ray source 2FGLJ0808.2-0751. We obtained NIR photometry for this object on May 15th,2016 (JD2457523.6334) and found it with an enhanced flux corresponding to H = 14.965 +/- 0.06. While on JD2457493.7, we detected this object at H = 16.239 +/- 0.04. Hence, the object has increased its luminosity by a factor of ~ 3 during this rather short lapse. At the time of the 2mass NIR survey there this object had a flux corresponding to H = 15.141 +/- 0.07. 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.
