We report on a new NIR Flare of the QSO BZBJ0424+0036 (z=0.31), also known as HB890422+004, associated with the gamma-ray source 2FGL0424.7+0034. Our NIR photometry for this source on Dec 31st, 2014 (JD2457022.7715), shows a significant increase of flux, corresponding to J = 12.636 +/- 0.05, H = 11.918 +/- 0.03 and Ks = 11.094 +/- 0.04. These values are about 0.8 magnitudes brighter than our previous photometry (JD2456963.842) for this field. Hence the object doubled its flux in a lapse of 60 days. The object started rising its flux since JC 2456649 (Atel#5712) and it is presently brightest since the time we started monitoring it at NIR wavelengths on JD2455242. 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.
