  We report on the discovery and analysis of an X-ray pulsar, AX J0058-7203, in
the Small Magellanic Cloud. This pulsar exhibits coherent pulsations at P=
280.3 s with a double-peak structure. The X-ray spectrum is well fitted with a
simple power-law model of photon index ~ 0.7. No significant change of the
pulsation period over the observation was found. A comparison with ROSAT
observations in the same field reveals that AX J0058-7203 is highly variable,
and is most likely a Be star binary pulsar.
