Coincidence of the brightness minima with aspect angle near 90 degrees. With a continuous line we show the sine of the aspect angle of Chiron as a function of time using the preferred pole solution (λ = 144°, β = 24°). The dotted line corresponds to the other solution for the pole direction (λ = 352°, β = 37°). The square symbols represent the absolute magnitude of Chiron from Belskaya et al. (2010) divided by a factor 5 for easier viewing. As can be seen, there is coincidence between aspect angle and absolute magnitude, but there is a shift between the aspect angle maxima and the absolute magnitude maxima for the λ = 352°, β = 37° pole solution.
