Following the reports (Atel#5981, Atel#5921) of the recent outburst of the flat spectrum radio quasar PKS122+219 (z=0.432), also known as 4C+21.35 and associated with the Gamma-ray source 2FGLJ1224.9+2122, we carried out NIR photometry of this source on March 19th,2014 (JD 2456735.847572). We found the source to have fluxes corresponding to J = 13.093 +/- 0.06, H = 12.314 +/- 0.07 and Ks = 11.378 +/- 0.04. These fluxes are the brightest since the epoch in which we starting monitoring this source at NIR wavelengths (JD2455184). 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.
