We report on a significant NIR brightening 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 June 12th,2016 (JD2457551.825), the object brightness corresponded to J = 13.561 +/- 0.03, H = 12.705 +/- 0.03 and Ks = 11.835 +/- 0.04. The NIR fluxes in the JHK bands had an increase, since our previously observed fluxes were: J = 14.182 +/- 0.05, H = 13.369 +/- 0.05 and Ks = 12.468 +/- 0.04, on JD2457539.88. Hence, the object has increased its luminosity by a factor of about 2 in this rather short lapse. The object has shown flaring activity in different wavelength bands in the past. (see ATEL # 5416 #5422 #7587 #7799 #7805). 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.
