We report a new NIR flare of the blazar S41030+61 a z=1.4 Flat Radio QSO also known as SDSS J103351.42+605107.3 and CGRaBS J1033+60518, identified with a flaring FERMI/LAT source in Atel#2625 1FGLJ1033.8+6048 reported by Ciprini et.al in (ATel #2622).On Atel#2628 Swift confirmed S41030+61 as a counterpart of 1FGLJ1033.8+6048. After an initial NIR flare reported in Atel #2625, we observed an increase to a maximum brightness H = 13.065 +/- 0.02 on May 25,2010 (JD2455339.6747) and a decline afterwards. On June 20,2010 (JD 2455367.66861) the source had fainted down to H = 14.168 +/- 0.02. Yet on November 28, 2010 (JD2455530.039537) we found that the source is undergoing a new NIR flare and its luminosity was back to the maximum light previously observed H = 13.073 +/- 0.02. The observations were carried out with the 2.1m telescope of the Guillermo Haro Observatory of the National Institute for Astrophysics, Optics and Electronics (Mexico), equipped with the instrument CANICA a NIR. We encourage further multi wavelength coverage for this interesting variable source.
