We report on an going 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 April 30th,2019 (JD2458603.9027), the object brightness corresponded to J = 13.088 +/- 0.03, H = 12.221 +/- 0.03 and Ks = 11.421 +/- 0.04. The NIR fluxes in the JHK bands had an increase, since our previously observed fluxes were: J = 13.864 +/- 0.05, H = 13.021 +/- 0.05 and Ks = 12.421 +/- 0.04, on JD2458597.9201. Hence, the object has increased its luminosity by a factor of about 2 in this very short lapse. The object has shown flaring activity in different wavelength bands in the past. (see ATEL # 5416 #5422 #7587 #7799 #7805 #9160). 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.
