We report the detection of a photometric period of 3h09m23s from the optical counterpart of RX 11141.3- 6410. The amplitude of the optical modulation, 11m,...., 0.5 mag, and the period are consistent with the suggestion that this is an AM Herculis star. Quasi-periodic oscillations (QPOs) with time-scales in the range 20.0-42.1 min are also reported
