Following the report on MASTER OTJ013135.43+555831.5 by Denisenko et al.,2014 (Atel #6432), and our recent NIR flux determination (Atel #6642), we carried out follow up NIR photometry recently. On October 31st,2014 (JD2456961.8454), we found the object with fluxes corresponding to J = 13 .974 +/- 0.07, H = 12.829 +/- 0,06 and Ks = 11.699 +/- 0.04. These fluxes are about 60% brighter, on the average, than the photometry obtained by our group less than a month ago. Photometric colors are consistent with the object being and AGN. We will continue monitoring its behavior in the NIR in order to correlate those data with other time variable data. Our observations were carried out with the 2.telescope of the Guillermo Haro Observatory of the National Institute for Astrophysics, Optics and Electronics (Mexico), equipped with the instrument CANICA a NIR camera. We encourage further multi wavelength coverage of this object.
