We report on the NIR flare of the high redshift quasar PKS0446+112 (z=1.207), also known as CGRaBSJ0449+1121, associated with the gamma-ray source 1FGL0448.6+1118. The source has shown Gamma-ray flares in the past. Our NIR photometry for this source shows that on Jan 4th,2014 (JD2456661.773275), the object brightness corresponded to J = 15.43+/- 0.04, H = 14.210 +/- 0.04 and Ks = 13.455 +/- 0.06. These values are about 1 magnitud brighter than our previous photometry, obtained on JD2456609, for this field. Hence it has doubled its flux in the last 50 days. The object is brightest since we started monitoring it on JD 2455275. 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.
