In late November of 1997 an RXTE slew which passed over the location of SMC X-3 detected a source in outburst. Its proximity to SMC X-3 triggered a ToO proposal for a pointing on the region. This and subsequent observations spanning from November 24, 1997 to March 25 1998 have uncovered the surprising result that, while SMC X-3 was not detected in outburst, no fewer than five new transient pulsing sources were! With periods ranging from 46 to 169 seconds, each pulsar is within a degree of the position of SMC X-3. Follow-up ASCA observations were used to locate the sources.
A brief observational history of the sources follows:
