We report on the recent NIR flare of the blazar CTA 026 (PKS0336-019) a high redshift quasar (z=0.852), associated with the Gamma-ray source 2FGLJ0339.4-0144, On October 31st, 2014 (JD 2456961.887894), We determined the flux from this object to correspond to H = 13.260 +/- 0.06. That is about 1 mag brighter than the previous flux value determined by us. On JD2456944.86716, we found the source with a flux corresponding to H = 14.273 +/- 0.03. Henceforth, this QSO has had a very significant increase in flux by a factor of 2.5 in this rather short lapse. This rise may be related with the Gamma-Ray flare reported by Ciprini et.al., 2014 (Atel #6568). This object is included in our NIR monitoring program of Gamma Ray bright AGNs. Our observations were carried out with the 2.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.
