We report on a NIR flare of the high redshift QSO PKS0336-019 (z=0.852), also known as CTA026 associated with the gamma-ray source 2FGL0309.1+1027. Our most recent NIR photometry for this source shows that on January 12th,2016 (JD2457399.7414), the object brightness corresponded to H = 13.558 +/- 0.06. In a previous observation in this band (MJD2457375.78) this object had H = 14.563 +/- 0.03. Hence, the object has increased its luminosity by a factor of 2.5 in this 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.
