Top: rotational light curve of 2003 VS₂ from data collected on 2019 October 24 (black triangles) and 25 (blue squares). The data were folded using the rotation period of 7.41753 h (Santos-Sanz et al. 2017). The fourth-order Fourier fit is shown as a solid red line. The vertical black-dashed line indicates the rotational phase of 2003 VS₂ at the time of the stellar occultation. The plot has been arbitrarily shifted to make the minimum of the fit (maximum brightness) correspond to rotational phase 0. Bottom: differences between the observational data and the fit. Julian dates have not been corrected for light travel time.
