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 January 13th,2015 (JD2457035.84546) the object brightness corresponded to J = 13.52 +/- 0.02, H = 12.74 +/- 0.03 and Ks = 11.942 +/- 0.04. These values are about 0.5 magnitudes brighter than our previous photometry, obtained on JD2457032.873, for this field. Hence it has almost doubled its flux in a lapse of 3 days. The object is brightest since we started monitoring it on JD 2455241. 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.
