Following the confirmation of this source as a Blazar by E. Breedt et.al (Atel #4606), we have observed a recent NIR brightening of the intermediate redshift, CSS120103:002748-055559 , cross identified with source GALEX2673601078639985212 (z=0.428). On November 28th 2012 (JD 2456259.701814), we determined the NIR flux in the following bands: H = 14.939 +/- 0.09, J = 15.602 +/- 0.11 and K = 14.415 +/- 0.11, these values yield colors which clearly consistent with to those of blazars. The source was not detected at the epoch of the 2MASS survey when an upper limit at 1.25 microns was J > 17.5 . 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
