Remarks: (1) consecutive intervals do not overlap according to error. Therefore double the period P=3.39 $\pm$ 0.02 is not impossible. Using only data with airmass smaller than 1.5 leads to exactly the same lightcurve just with fewer available points (77 in V); (2) in run III the period was constrained to P=3.0109 $\pm$ 0.0002 d; (3) superposition of two distinct periods probable: 0.6 and 1.8 days; (4) eclipse, not spots; (5) half of the period possible as well; (6) smallest string-length at 3 times the period in all filters; (7) period larger than duration of observations. Determination of period by sinus fitting; (8) the confidence interval is not symmetric. The period is in the interval: $P\in [6.4,8.7]$ days; (9) completely different amplitude than in 1998 (factor two), but the same periodicity (Run I: 2.24 $\pm$ .12 days).
a $\Delta m$ = $\rm maximum\; value-minimum\; value$.
b $\Delta m$ = 2 $\times $ amplitude of fitted sinus curve.
