We have observed a recent NIR brightening of the high redshift quasar HB890133+476 (z=0.856), a gamma ray source 1FGL J0137.0+4751. On October 23th,2012, epoch JD2456223.903056, we determined its flux in the H band to be 13.921 +/- 0.05. That is 0.9 magnitudes brighter than flux we had determined a month ago on epoch JD2456196.970671 H = 14.807 +/- 0.06. 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 encourage further multi wavelength coverage.
