We report on a NIR brightening of the high redshift Blazar S41030+61 (z=1.409), also known as BZBJ1033+6051 associated with the gamma-ray source 3FGLJ1033.8+6051. Our most recent NIR photometry for this source shows that on December 28th,2017 (MJD 2458117.0313), the object brightness corresponded to H = 13.748 +/- 0.03, J = 14.789 +/- 0.03 and Ks = 12.770 +/- 0.05. In our previous observation in these bands (MJD2457827.924), the object had H = 15.106 +/- 0.03, J = 15.596 +/- 0.03 and Ks = 13.969+/- 0.05. Hence, the object has increased its luminosity by a factor of about 3 in this lapse. Previous activity in this object had been reported (Atel#2625, #3062, #3287 #8715). 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 strongly encourage further multiwavelength coverage.
