We report on the recent fast rising NIR flare of the flat spectrum radio source PKS0502+049 a high redshift quasar (z=0.954) also known as CGRaBS J0505+0459, associated with the Gamma-ray source 2FGLJ0505.1+0501, On October 4rd, 2014 (JD 2456934.9888), We determined the flux from this object to correspond to J = 14.280 +/- 0.05, H = 13.484 +/- 0.05 and K = 12.546 +/- 0.05. That is about 1 mag brighter than the flux value measured by our team 24 hours earlier. On JD2456933.966030, we determined a flux corresponding to H = 14.592 +/- 0.05. Henceforth, this QSO has had a a very significant increase in flux by a factor of 2.8 in this very short lapse. This object is included in our NIR monitoring program of Gamma Ray bright AGNs. Our observations were carried out with the 2.telescope of the Guillermo Haro Observatory of the National Institute for Astrophysics, Optics and Electronics (Mexico), equipped with the instrument CANICA a NIR camera. We encourage further multi wavelength coverage of this object.
