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 March 18th,2017 MJD(2457830.6328), we found the source with NIR fluxes corresponding to J = 14.194 +/- 0.05, H = 13.531 +/- 0.05 and Ks = 12.629 +/- 0.02. While, on MJD 2457762.08 the flux in the H band corresponded to H = 15.481 +/- 0.04. Hence, the source has increased its flux by a factor of 6 in this short lapse. The source is brightest since the time we started monitoring it on MJD 2454747.9. The source has presented important variability in the past in Gamma ray and NIR wavelengths (see ATEL #6568, #6662 and #8575).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.
