We report on the recent NIR flare of the high redshift QSO (z=1.213) [hb89]0234+285 also known as BZQJ0237+2848, cross correlated with the radio source 4C+28.07 and the Gamma-ray source 2FGLJ0237.4+2846. On January 19th,2017 MJD(2457772.72), we found the source with NIR fluxes corresponding to J = 14.529 +/- 0.03, H = 13.764 +/- 0.03 AND Ks = 13.004 +/- 0.03. While, on MJD 2457760.80 the flux in the H band corresponded to H = 14.938 +/- 0.03. Hence, the source has tripled its flux in this rather short lapse. 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.
