We report on the recent Giant NIR flare of the high redshift blazar PKS0454-234 (z=1.003), cross identified with the source BZQJ 0454-2324 and the Gamma-ray source 2FGLJ0457.0-2325. On September 7th,2015 (MJD 2457272.987), we found the source with the following fluxes in NIR bands: J = 13.751 +/- 0.07, H = 12.962 +/- 0.02 and Ks = 11.910 +/- 0.08. These are to be compared with our previous observation on MJD 2456729 , when the source had H = 15.061. Hence the source has had a flux increment of a factor of 7 in this lapse. The source has shown flare activity in the past (see ATEL #3722,#4647, #5583) 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.
