We report a further NIR brightening of the non-thermal Radio Source PMNJ0633-3350, also known as CRATES J0623-3350. On February 8th,2019 (MJD 2458522.7100), we found the source with NIR fluxes corresponding to J = 14.813 +/- 0.03, H = 13.968 +/- 0.03 and Ks= 13.070 +/- 0.04. While on MJD 2458488.81 the flux in the H band was H = 14.154 +/- 0.07. Hence, the source has increased its flux by at least factor of 2.8, in this short lapse. The source is brightest since the time we started monitoring it on MJD 2456646, when the source was H = 15.575 mag. This event seems to be an extension of the flare reported in ATel #12381. 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 multi-wavelength coverage.
