我们目前的结果，五色测光观测的SU UMa系统VW Hyi，在1984年11月的超级爆发的六个晚上。光变曲线以超峰变化为主，其振幅在所有通带中随时间减小（在V带中，从超爆发达到最大亮度后约4.5天的0.16等，到约5天后的0.10等）。超峰光变曲线强烈地依赖于波长。特别是，不同通带中的光变曲线似乎相互偏移：波长越大，光变曲线延迟越多。
We present results of five-colour photometric observations of the SU UMa system VW Hyi, made on six nights during the November 1984 superoutburst. The light curve is dominated by superhump variations, whose amplitude in all passbands decreases with time (in theV-band from 0.16 mag about 4.5 day after the superoutburst reached maximum brightness, to 0.10 mag about 5 day 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.
