We report on a new, recent 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 November 20th, 2015 (MJD 2457346.559) We determined the flux from this object to correspond to J = 14.614 +/- 0.03, H = 13.795 +/- 0.04 and Ks = 13.003 +/- 0.05. That is about 1.5 mag brighter than the flux value measured by our team previously. For MJD2457297, we determined a flux corresponding to J = 16.055 +/- 0.03 , H = 15.314 +/- 0.02 and Ks = 14.165 +/- 0.04. Henceforth, this QSO has had a significant increase in flux by a factor of about 4 in this lapse. The object has shown flaring activity in the past (ATEL #3302, #6614, #7807). The object is now brightest since the time we started monitoring it on MJD2455322, 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.
