We report on a new NIR flare of the QSO TXS 2241+406 also known as BZB J2244+4057 (z=1.171), associated with the Gamma ray source 2FGLJ2244.1+4059. On December 1st,2014 (JD, 2456992,640470) we obtained NIR photometry for this object and found it with enhanced fluxes corresponding to: J = 14.496 +/- 0.06, H = 13.589 +/- 0.07 and Ks = 12.662 +/- 0.07. The object is brightest since the epoch in which it was included in our regular monitoring program of NIR photometry. 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, since then, it has increased its flux by about a factor of ~50. The present flare shows an increment in flux of a factor of 4.7 since we first detected this object on JD 2456650 (Atel #5690) and it is brighter than the flare previously reported in Atel # 6402. 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.
