Overview of all 58 currently available optical light curves archived at the CDS (, Marciniak et al. 2021). Given is the relative brightness (in intensity units) normalized to the mean brightness vs time (MJD) for the time span 2007-2020. The maximum amplitude Amax for the epoch around MJD 55950 is 0.16 mag and corresponds to a nearly equatorial view; see Fig. 1 (right panel). The LCDB ( provides the values Amin = 0.06 mag and Amax = 0.13 mag.
