eROSITA light curve of eRASSU J052914.9−662446 in the five epochs from eRASS0 to the beginning of eRASS5. Each point represents a single scan over the source. The dotted green, red, and orange lines indicate the date of the SALT, Swift, and NuSTAR follow-up observations, respectively. The dotted black lines indicate the formal transitions between different eRASSs. Error bars in the y-direction show the 1σ uncertainties assuming Poisson statistics. Count rates of bins with fewer than ten counts are plotted as 1σ upper limits.
