We report on a new giant NIR flare of the intermediate redshift QSO BZQJ1512-0905 (z=0.36), also known as PKS1510-089 associated with the gamma-ray source 2FGLJ1512.8-0906. Our most recent NIR photometry for this source shows that on July 16th,2015 (JD2457219.7525), the object brightness corresponded to J = 12.028+/- 0.05, H = 11.222+/- 0.04 and Ks = 10.321 +/- 0.03. The NIR fluxes in the JHK bands had a sudden increase, since our previously observed fluxes were: J = 13.614 +/- 0.04, H = 12.750 +/- 0.05 and Ks = 11.846 +/- 0.04, on JD2457180.6762. Hence the object has increased its luminosity by a factor of about 4 in this rather short lapse. The object has shown flaring activity in different wavelength bands in the past. (see ATEL # 5416 #5422 #7587 #7799). 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.
