We report on a new NIR flare of BZQ J1727+4530 (B31726+455) an intermediate redshift quasar (z=0.717) also known as CGRaBS J1727+4530, associated with the Gamma-ray source 2FGLJ 1727.1+4531. On July 16th, 2015 (MJD 2457219.9008) We determined the flux from this object to correspond to J = 14.980 +/- 0.02, H = 13.972 +/- 0.05 and Ks = 12.945 +/- 0.07. That is about 2.5 mag brighter than the flux value measured by our team previously. For MJD2456803.6455, we determined a flux corresponding to J = 16.868 +/- 0.06 , H = 16.224 +/- 0.09 and Ks = 15.359 +/- 0.04. Henceforth, this QSO has had a significant increase in flux by a factor of about 10 in this lapse. The object has shown flaring activity in the past (ATEL #3302, #6614). The object is brightest since the time we started monitoring it on MJD2455322.905, Our observations were 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.
