Abstract: Schwope et al. (1997) suggested that the newly discovered polar RX J2115-5840 is a near-synchronous system. We have obtained circular polarisation observations of RX J2115-5840 which show that the spin and orbital periods differ by 1.2%. We find the first direct evidence of `pole-switching' in a near-synchronous polar. Further our data require that the accretion flow must be directed onto the same magnetic field line at all spin-orbit beat phases, implying that at some phases the flow must follow a path around the white dwarf before accreting.
