We report on a NIR flare of the low redshift quasar PKS0736+017 (z=0.189), also known as CGRaBSJ0739+0137, associated with the gamma-ray source 2FGL0739.2+0138. Our NIR photometry for this source shows that on February 12th,2014 (JD2456670.884), the object brightness corresponded to J = 13.55 +/- 0.02, H = 12.78 +/- 0.02 and Ks = 11.828 +/- 0.06. These values are about 0.8 magnitudes brighter than our previous photometry, obtained on JD2456696.8, for this field. Hence it has doubled its flux in a lapse of 4 days. The object is brightest since we started monitoring it on JD 2454591. 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.
