We report on the NIR brightening of the high redshift QSO BZQJ0206-115 (z=1.663). On October 2nd, 2017 MJD(24578029.89), we found the source with NIR fluxes H = 15.697 +/- 0.07. While, on MJD 24576935.89 the flux in the H band corresponded to H = 16.41 +/- 0.07. Hence, the source has increased its flux by a factor of 2 in this lapse. The source is known to have undergone flaring activity in the past as on MJD 2455501.9 when the source was brightest (H = 13,567 +/- 0.05) since the time the 2mass survey was carried out, when the flux in the H band was fainter then H > 17.5. 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.
