We report on the recent brightening of the AGN candidate MASTER OTJ013135.43+555831.5. On August 6th,2018 MJD(2458336.986), The source had NIR fluxes corresponding to J = 14.665 +/- 0.05, H = 13.397 +/- 0.05 and Ks = 12.384 +/- 0.05. While on MJD 2458116.708 the flux in the H band corresponded to H = 16.005 +/- 0.04. Hence, the source increased its flux by a factor of 11 in this lapse. This fact and its NIR colors render further support to the observed NIR colors render support to the idea that it is an AGN. Spectroscopic data is highly desirable. 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 multiwavelength coverage.
