I wanted to note that based on the period of the (super)humps Patterson et
al. (1981, ApJ 248, 1067) found that humps with a period different from
the orbital period appeared 10-11 days after the peak of the outburst,
suggesting that "true" superhumps started around then.
I also wanted to note that I'm impressed by the nice and detailed light
curves all the people are getting. Really `super'!
