U,B, and V observations of AR Lacertae, obtained in 1981, have been presented alongwith the colour indices. A distortion wave minimum is found to lie at 0p.21. The amplitude of the wave minimum in B filter is too weak, while it is stronger in U and V filters, the strongest being in V filter. The period of the migration wave turns out to be 2.53 yr.
