Data observed from OPC in the B, V, and R bands in February 2021 and December 2021 and in V, R, and I bands in February 2022. The plotted line is an estimation of the flux variation of the star obtained by fitting the data by using a sinusoidal function with an offset. For the observations of February 2022 and for the first day of observation of December 2021, B band data were discarded given their signal-to-noise ratio (S/N) of < 20.
