Following the report of the Gamma-ray flaring of this object by the Fermi LAT collaboration,(Roopesh Ojha et.al,2015 ATEL#8319) We observed a recent NIR flare of the FSQR TON599 a high redshift blazar (z=0.724488) associated with the Gamma-ray source 3FGL J1159.5+2914, On November 23nd, 2015 (JD 2457349.0468), We determined the flux from this object to correspond to J = 13.547 +/- 0.04, H = 12.694 +/- 0.06 and Ks = 11.931 +/- 0.06. That is about 1.3 mag brighter than the flux value measured previously by our team. On JD2457221, we determined a flux corresponding to H = 13.939 +/- 0.06. Henceforth, this blazar has had a significant increase in flux, in the H band, by a factor of about 4 in this lapse. This object is included in our NIR monitoring program of Gamma Ray bright AGNs.. Our observations are carried out with the 2.1m telescope of the Guillermo Haro Observatory of the National Institute for Astrophysics, Optics and Electronics (Mexico), equipped with the instrument CANICA a NIR camera. We encourage further multi wavelength coverage of this object.
