We report on a new NIR flare of the high redshift Blazar 3c454.3 (z=0.859), also known as HB89 2251+158 associated with the gamma-ray source 2FGL2253.9+1609. Our most recent NIR photometry for this source shows that on January 14th,2016 (JD2457401.6211), the object brightness corresponded to H = 11.793 +/- 0.02. In a previous observation in this band (MJD2457374.6685) this object had H = 13.387 +/- 0.03. Hence, the object has increased its luminosity by a factor of about 4.5 in this rather short lapse. 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.
