The flat spectrum radio source PMN J1336-1529 wss detected by the FERMI(LAT) instrument in March, 2021 (ATel # 14474).
On JD 2459307.9732 and JD2459308.962396, we found the source with NIR fluxes corresponding to H = 15.819
+/- 0.064 and H = 15.864 +/- 0.054 respectively. Yet, on JD2459666.8906 (March 22th,2022), we found the source with a flux corresponding to H = 13.575 +/- 0.027. Hence, the source has increased its NIR flux by
2.23 magnitudes or a factor of 8.2 in such lapse. Worth notice is the fact that the 2MASS all sky survey did not detected this source. These facts, imply that PMNJ1336-1529 is undergoing a NIR flaring event. 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.
