Following the report on flaring activity of MASTER OTJ010728.48+033348.4 by Shumkov et al.,2014 (Atel #6762). We carried out NIR photometry recently, On November 30th,2014 (JD2456991.8114), we found this object with a flux corresponding to H = 15.754 +/- 0,05, J = 15.754. +/- 0.,05 and Ks = 14.436 +/- 0.06. The object is coincident with the radio source PMNJ0107+0333 and the Rosat source 1RXJ010729.5+033341. The NIR colors are consistent with those of AGN's. These flux values are more than 2 magnitudes brighter than the upper limits in the 2MASS Survey, confirming the variable nature of this object at NIR wavelengths. We plan to follow its behavior in the NIR in order to correlate those data with other time variable data. Our observations were carried out with the 2.1m 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.
