Long-term light curves of the continuum flux density at 5050 Å (in units of 10−15 erg s−1 cm−2 Å−1), as well as of the line fluxes of Hα, Hβ, Fe II(42,48,49) (in units 10−15 erg s−1 cm−2), and the BD for the years 1997 until 2024. The right panel shows the observations from 2017 to 2024 in more detail.
