We report on the recent Giant NIR flare of the intermediate redshift FSRQ PKS2032+107
(z=0.601), cross identified with the source BZQJ 2035+1056 and the Gamma-ray source 2FGLJ2035.4+1058. On September 6th,2015 (MJD 2457271.7273), we found the source with the following fluxes in NIR bands: J = 13.969+/- 0.06, H = 13.212 +/- 0.03 and Ks = 12.116 +/- 0.07. These are to be compared with our previous observation on MJD 2457142.97, when the source had, J = 15.512, H = 14.909 and Ks = 14.172. Hence the source has had an increment of about 2 magnitudes, in this lapse. Worth mentioning is the fact that on JD 2457271, we observed the source twice and found and increase in the H band of 35% in flux in the very short lapse of 1.5 hours. The source has shown flare activity in the past (see Atel #7588, #7453) Our observations are 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 multiwavelength coverage.
