We report on a new NIR flare of the high redshift QSO (z=0.852) of the radio source CTA026 cross identified with the quasar BZQJ0336-019, and the Gamma-ray source 2FGLJ0339.4-0144. On December 11th, 2025 (JD 2461020.7727), we found the blazar with an increased NIR flux corresponding to H = 14.130 +/- 0.03. While, on JD 2460755.625220 the flux in the H band corresponded to H = 16.229 +/- 0.05. Hence, the source has increased its flux by a factor of about 7 in this time interval. In the past, the source has presented important variability in Gamma ray and NIR wavelengths (see ATEL #6568, #6662, #8575, #10185). 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
