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.
