Evolution of the Hα and He I 5876 Å line luminosities of TDE AT2018fyk plotted with black and empty X-marks respectively and Swift UVW2 band light curve (Wevers et al. 2019a) plotted in blue circles. All luminosity curves are normalized to one. The line luminosities respond to variations of the light curve with a small lag for Hα and a larger one for He I.
