We report on the recent NIR brightening of the large redshift (0.874), flat spectrum, radio quasar PMNJ1923-2104. On September 28th,2018 MJD(2458389.63976), The source showed a NIR flux corresponding to H = 13.269 +/- 0.04. While on MJD 2458025.684, the flux in the H band corresponded to H = 15.694 +/- 0.04. Hence, the source increased its flux by a factor of 10 in this lapse. The source is brightest since the time we started monitoring it on MJD 2544982. 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 encourage further multiwavelength coverage.
