We report on a recent NIR flare of the high redshift QSO HB89 0235+164 (z=0.94) also known as BZB J0238+1636, associated with the Gamma ray source 2FGLJ0238.7+1637. On December 29th,2014 (JD, 2457020.8185), we obtained NIR photometry for this object and found it with enhanced fluxes corresponding to: J = 14.791+/- 0.02, H = 13.718 +/- 0.02 and Ks = 12.848 +/- 0.05. While on JD 2456992.7084, we detected thia object at J = 15.950 +/- 0.05, H = 14.941 +/- 0.03 and Ks = 14.001 +/- 0.03. Hence it shows an increment of its flux by a factor of 3 in a rather short lapse of 28 days. Our observations were 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 strongly encourage further multiwavelength coverage.
