Following the Gamma-ray flare detection by Fermi/LAT (ATel# 13032) and the brightening in visible light (ATel#13038) of the Flat spectrum radio source TXS0025+197. We observed the source on August 21st,2019 (MJD 2458716.967) finding the source with the following fluxes in the NIR;
J = 14.984 +/- 0.03, H = 14.085 +/- 0.03, Ks = 13.245 +/- 0.02. While the flux in the H band on
MJD 2458523, was 16.665 +/- 0.06. Hence, the object has increased its NIR flux by a factor of 11
in this rather short 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.
