We report the ongoing NIR flare of BZU J0742+5444 (GB6 J0742+5444) an intermediate redshift quasar (z=0.72). On February 26th, 2015 (JD 2457079.771668), we detected a rather strong brightening of this source in the NIR. We determined the flux from this object to correspond to H = 14.895 +/- 0.04. That is 2.2 mag brighter than the flux value (H = 17.109 +/- 0.05) we determine for the epoch JD 2457033.83. Henceforth, this QSO has had a significant increase in flux by a factor of almost 7 in this short lapse. The object has shown flaring activity in the past (see Atel #3261). 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.
