We report on the recent NIR brightening of the Quasar PKSJ0417-0250 also known as PKSB0415-029. On February 8th,2019 MJD(2458522.7668), The source showed a NIR flux corresponding to H = 14.851 +/- 0.03. While on MJD 2458511.7031, the flux in the H band corresponded to H = 16.504 +/- 0.04. Hence, the source increased its flux by a factor of 4.5 in this short lapse. The source has shown flare activity in the past see ATel#5899,#5977,#12098. Spectroscopic data is highly desirable. 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 multiwavelength coverage.
