We report on the present NIR flare of the quasar TON599 also known as FBQS J115931.8+291443 (z=0.7245), cross identified with the gamma ray source 1FGLJ11.59.4+2914
and the radio source 4C+29.45. On February 23rd,2013, epoch JD2456346.946968, we determined the flux in the H band to be 13.129 +/- 0.03 and J = 14.082 +/- 0.03. That is about 1.5 magnitudes brighter than the flux we determined previously for this object, on JD2456327.883532 when we found the object to be H = 14.600 +/- 0.05. and J = 15.668 +/- 0.03. The object is brightest since the epoch at which we started monitoring it in NIR wavelengths (JD 2454589). 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
