The relative magnitude versus rotational phase obtained two days after the occultation with the Valle D’Aosta 0.81-m telescope with no filters is shown. The rotational zero phase was established at the time of the occultation and the rotation period used was 3.915341 h. Superimposed is a fit to the observational data. As can be seen, the absolute maximum in magnitude (absolute brightness minimum) is reached at the time of the occultation (arbitrarily located at a phase of 0 here), which means that the projected area of Haumea was also at its minimum. The continuous line is a fit to the data. The peak-to-peak amplitude of the light curve is 0.25 ± 0.02 mag. Error bars are 1σ.
