Scientific paper

Results of five-color photometric observations of the SU UMa system VW Hyi, made on six nights during the November 1984 superoutburst, are presented. The light curve is dominated by superhump variations, whose amplitude in all passbands decreases with time (in the V-band from 0.16 mag about 4.5 days after the superoutburst reached maximum brightness, to 0.10 mag about 5 days later). The superhump light curve depends strongly on wavelength. In particular it appears that the light curves in different passbands are mutually shifted: the larger the wavelength is, the more the light curve is delayed.
