Following the report of the Master OTJ141922.56-083831.7 (Atel #7133), we have observed the further development of a recent Giant NIR flare of the Blazar candidate NVSSJ141922-083830, cross identified with the gamma ray source 2FGL J1419.4-0835. On February 28th, 2015, epoch JD2457081.0378, we determined the flux in the H band to be 13.492 +/- 0.07. That is about 5 magnitudes brighter than the flux previously determined by us on JD2455676, when we found this object at a flux level corresponding to H ~ 18.5 +/- 0.1. 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. Spectroscopic observations are highly desirable, we encourage further multi wavelength coverage.
