We report on the recent NIR brightening of the intermediate redshift Blazar 3C345 (z=0.593415), associated with the FBQS J164258.7+394837. On June 4th,2021 (JD 2459369.904028), we found the source with NIR fluxes corresponding to: J =14.614 +/- 0.04, H = 13.975 +/- 0.05, Ks = 13.240 +/- 0.06. On JD 2459358.983935. we had determined the flux H = 14.507 +/- 0.03 for this object. Hence, the object has undergone an increase in flux of a factor of 1.6 in this short period of time. 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.
