We report on the present NIR flare of the high redshift quasar BZQJ1127-1857 also known as RBS0985 (z=1.05), cross identified with the gamma ray source 1FGLJ1126.8-1854 and the radio source PKS1124-186 On January 21th,2013, epoch JD24564.017095 we determined the flux in the H band to be 12.901 +/- 0.07 and J = 13.102 +/- 0.07. That is about 1.2 magnitudes brighter than the flux we determined previously for this object, on JD2456093.6717, when we found the object to be H = 14.075 +/- 0.03. and J = 14.806 +/- 0.03. The object is brightest since the epoch at which we started monitoring it in NIR wavelengths (JD 2455330).TH object has shown flares in gamma rays and in visible and NIR light in the past (Atel #3207 and #3212). 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
