We report on the recent NIR flare of the intermediate redshift QSO (z=0.5362) 3C279 also known as [HB89] 1253-055 , cross correlated with the Gamma-ray source 2FGLJ1256.1-0547. On March 5th,2017 MJD(2457817.8422), we found the source with NIR fluxes corresponding to J = 12.057 +/- 0.05, H = 11.633 +/- 0.05 and Ks = 10.459 +/- 0.06. While, on MJD 2457790 the flux in the H band corresponded to H = 12.359 +/- 0.06. Hence, the source has doubled its flux in this short lapse. 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 encourage further multi wavelength coverage.
