We call attention on our recent NIR observation of the Gamma Ray source 1FGLJ1553.4-2425 also known as PKS1550-242. On March 17th,2019 (JD2458560.11), we found the flux of the object to correspond to H = 14.630 +/- 0.04. While on MJD 2458543, the source flux corresponded to H = 16.084 +/- 0.04. Hence the source's flux has increased by a factor of 3.8. A very significant increase in luminosity in this lapse. Our observations are 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 encourage further multi-wavelength coverage.
