We report on the recent observation that revealed a NIR flare of the quasar CGRaBSJ2348-1631 cross identified with the Gamma-ray source 2FGLJ2347.9-1629 On October 31th,2013 (JD 2456596.82308), its flux in the H band corresponded to the magnitude H = 12.985 +/- 0.09. This value is to be compared with our previous photometry for this object H = 15.472 +/- 0.06, on JD2456547.851748. Hence, this object has increased its brightness by a factor 0f 10 in the last 50 days. Our observations were 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 multi-wavelength coverage of this transient event.
