   We propose an ASCA long-term observation of the southwest region of the
   SMC. At this region, a supergiant HI shell (SGS) is crossing the main
   body of the SMC, and there are many attractive X-ray sources. The
   purposes are, (1)to detect coherent pulsations from three pulsar
   candidates, (2)to monitor four known pulsars, (3)to search undetected
   transient sources, (4)to make systematic analyses of thermal SNRs, and
   (5)to reveal the relation between distribution of the X-ray sources and
   the SGS.
