Regular monitoring of the SMC with the Rossi X-ray Timing Explorer has revealed a large number of X-ray pulsars. One of these sources, a pulsar with a period of approximately 7.8 seconds, was first detected in early 2002. Since discovery it has been detected multiple times and the outburst pattern suggests an outburst period of approximately 40 days which is probably the orbital period of this system. We also provide an update on other pulsars discovered during our monitoring program.
