We report on an important NIR brightening of flat spectrum QSO PKSB0415-029. On November 14th,2017 MJD(2458071.997), we found the source with NIR fluxes corresponding to J = 16.881 +/- 0.04, H = 16.237 +/- 0.04 and Ks = 15.290 +/- 0.08. While, on MJD 2457829.655 the flux in the NIR corresponded to H = 17.295 +/- 0.04 and K = 15.290 +/- 0.07. Hence, the source has increased its flux by a factor of 2.7 in the H band in this 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.
