Abstract: I present a preliminary analysis of ongoing monthly X-ray observations of TX Col with RXTE. The lightcurves confirm that the relative strength of spin and beat modulations is highly variable in this system, and show that the timescale of variation is shorter than one month. Changes in these modulations are thought to represent a change in accretion geometry, possibly governed by a varying accretion rate. I find some evidence that the ratio of spin to beat amplitudes is correlated with the mean count rate.
