Following the report of a flare detected by Master (Shumkov et al.2013, Atel #5614) of the object TXS 2241+406 also known as BZB J2244+4057 (z=1.171), associated with the Gamma ray source 2FGLJ2244.1+4059. We obtained NIR photometry for it. We found that on Dec 24th,2013, JD 2456650.617361 the object yielded the following values: J = 16.267 +/- 0.03, H = 15.273 +/- 0.04 and Ks = 14.650 +/- 0.03. The object might have been at detection limit at the the time of the 2Mass survey\, with a flux corresponding to H ~ 17.8. Hence It has increased its flux by about a factor of 10. 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. .
