We report on the recent NIR brightening of the flat spectrum radio quasar PKS 1335-127 also known as QSO B1334-127, cross correlated with the Gamma-ray source 4FGL J1337.6-1257. On June 19th, 2025 (JD2460845.7728), we found the object undergoing a new outburst. The NIR flux in the H band corresponded then to H=13.912+/-0.055. This is a flux more than 3 times larger than a light minimum observed in a lapse of 12 days. For JD2460833.7471, the flux determined was H=15.225+/-0.055. Our observations are carried out with CANICA a NIR camera on the 2.1m telescope at the Observatorio Astrofisico Guillermo Haro, which is operated by the National Institute for Astrophysics, Optics and Electronics (INAOE, Mexico). We encourage further multiwavelength observations.
