We report on a fast NIR flare of the intermediate redshift QSO (z=0.576) [hb89]2345-167 also known as PKS2345-16, cross-correlated with the radio source and the Gamma-ray source 2FGLJ2347.9-1629. On January 5th,2019 MJD(2458488.6268), we found the source with NIR fluxes corresponding to J = 13.431 +/- 0.08, H = 12.536 +/- 0.07 and Ks= 11.772 +/- 0.05. While, on MJD 2458448.6193 the flux in the H band corresponded to H = 13.838 +/- 0.07. Hence, the source has increased its flux by a factor of 3.3, in 40 days. The source is brightest since the time we started monitoring it in NIR light on MJD 2455518. 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.
