We report on NIR photometry of the flat spectrum radio source PKS1004-217, cross identified with the intermediate redshift quasar CGRaBSJ1006-2159 (z=0.33) and the Gamma-ray source 3FGLJ1006.7-2159. Following the report of the flaring event detected by Fermi LAT (Atel#10952), We observed the source in the NIR, finding that on November 27th, 2017 (MJD 2458084.990012) its fluxes correspond to J = 15.032 +/- 0.03, H = 14.293 +/- 0.03 and Ks = 12.998 +/- 0.03. The flux in Ks is almost a factor of 2 brighter than the value reported in the 2MASS catalog. 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.
