We observed a recent NIR brightening of the flat spectrum radio source (+4C38.41) FBQSJ163515.4+380804 a high redshift blazar (z=1.813). On September 16th, 2012, epoch JD2456186.664525, we determined the flux in the H band to be 13.564 +/- 0.04. This flux level is comparable to the one reported previously in Atel #3335. The NIR flux of this object is rising fast. Yet, the object has not reached the flux level observed on JD 2455635.029352 H = 13.072 +/- 0.05 (ATel#3238). These photometric data points are to be compared with a recent low activity state H = 15.328 +/-0.06 (JD2456093.909456). Observations were 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.
