The authors present optical and IR observations of the dwarf nova OY Car during the May 1985 superoutburst. From them they find that the superhump has a temperature of ≡8000K and an area of order half the size of the red dwarf or accretion disk. The authors also compare the behaviour during two simultaneous optical/IR observations. Whilst the light curves in the two pass bands are similar during one observation, in the other observation they show marked differences that may be due to a cool region in the outer disk.
