We report on the recent NIR brightening of Flat Spectrum Radio Quasar (FSRQ) PKS J2301-0158, also known as PMN J2301-0157. On September 27th 2024 (JD 2460580.7707) we found the quasar PKS J2301-0158 in an historically bright NIR flare in a lapse over 9 years of our observations. The NIR fluxes in the JHK bands were: J=13.333+/-0.023, H=12.510+/-0.026 and Ks=11.730+/-0.044. While the NIR fluxes in the H band on JD2460251.7516 it was H=16.212+/-0.033. Hence, the object has increased its luminosity in the H band by a factor of 30 in this lapse. 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.
