We report on a NIR flare of the intermediate redshift QSO (z=0.576) HB892345-167 cross identified with the radio source PKS2345-16 and the Gamma-ray source 2FGLJ2347.9-1629 On November 12th,2017 MJD(2458069.7238), we found the source with NIR fluxes corresponding to J = 14.293 +/- 0.05, H = 13.456 +/- 0.04 and Ks = 14.341 +/- 0.06. While, on MJD 2458029.84 the flux in the NIR bands corresponded to J = 14.88 =/- 0.05, H = 14.078 +/- 0.04 and K = 13.263 +/- 0.06. Hence, the source has increased its flux by a factor of 1.8 in the H band in this 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.
