Following the report (Atel#6182) of the enhanced activity in Gamma Rays detected by AGILE of the FSRQ 3C453.3 (z = 0.859) associated with the Gamma-ray source 2FGL2253.9+1609, we carried out NIR photometry of this source on June 8th,2014 (JD 2456816.9487). We found the source to have fluxes corresponding to J = 12.326 +/- 0.05, H = 11.498 +/- 0.05 and Ks = 10.527 +/- 0.05. These values are to be compared with our previous photometry for JD 2456649.6509, when we found this source with a flux corresponding to J = 13.911+/- 0.04, H = 13.164 +/- 0.04 and Ks = 12.246 +/- 0.07. Hence, during this lapse, the source has had an increase in flux of a factor of 4.7 at NIR wavelengths. 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.
