Abstract
Data from the first observed outburst of the dwarf nova SDSS J094002.56+274942.0 show cyclical variations increasing in amplitude when the object fades. These variations are likely due to the ellipsoidal shape of the red dwarf and possibly also eclipses of the accretion disk. An orbital period of 3.92 hours is derived.
