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 recent NIR photometry for this source shows that on May 8th,2015 (JD2458611.6345) the object brightness corresponded to J = 13.44 +/- 0.02, H = 12.57 +/- 0.03 and K = 11.701 +/- 0.04. These values are about 1.7 magnitudes brighter than our previous photometry, obtained on JD2458582.6851, for this field. Hence it has increased its flux by a factor of 4.7 in a lapse of 29 days. The object is brightest since we started monitoring it on JD 2455241. The object has shown flaring activity in the past. 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.
