The superhump amplitude was modulated with phase of the beat period. The highest amplitudes (2A_max≈0.4 mag) occurred when the superhump maximum coincided with the orbital phases φ_orb≈0.15 and 0.65, while the lowest (2A_min≈0.2 mag) - with φ_orb≈0.40 and 0.90. The directions defined by those two pairs of orbital phases appear to be parallel and perpendicular to the direction of the stream.
