Following the report (Atel #5007) of the Optical and Gamma ray flaring of the Radio-Loud Narrow-Line Sy1 SBS 0846+513, z = 0.583. We followed the development of this event at NIR wavelengths. Our photometry indicates a slow increase in brightness in the time interval included between MJD 2456386.689780 and MJD 2456417.674421 of about 30%, reaching a flux value corresponding to H = 14.153 +/- 0.04 and K = 13.747 +/- 10.09 for the latter epoch. Yet on May 17th, 2013 MJD=2456429.687407, the source was found on a flaring state, with a flux corresponding to H = 13.574 +/- 0.05 and Ks = 12.57 +/- 0.11 an increase in flux of a factor of 3 in just 12 days. 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 strongly encourage further multi wavelength coverage of this interesting object.
