We report on the recent NIR brightening of the intermediate redshift Blazar HB892007+777 (z=0.342), associated with the Gamma-ray source 2FGLJ2004.5+7754 and the radio source 8C2007+777. On September 24th,2015 (MJD 2457289.8305), we found the source with NIR fluxes corresponding to: J = 13.293 +/- 0.02, H = 12.450 +/- 0.05 and Ks = 11.451 +/-3.253 0.04. On MJD 2457202.9. we had determined the fluxes to be J = 14.257, H = 13.412 and Ks = 12.544. Ever since, we have detected, in this object, a slow but monotonic increase in flux for the NIR part of the spectrum. 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.
