Observed photometric lightcurves (black symbols with error bars representing the 1σ photometric uncertainties) of Kamo‘oalewa from GN on 2026 April 20 (a), April 22 (b), and May 9 (d), and from LDT on May 7 (c). Overplotted are the best-fit models assuming non-principal-axis rotation using a triaxial ellipsoidal shape in LAM (orange solid curve) and SAM (red dashed curve) (see Section 4), and a convex shape in LAM (blue solid curve) (see Section 5). All lightcurves are plotted in linear flux scale and normalized to unity at their respective averages.
