    PR # 32138                                                                   
     Supergiant shells with diameters approaching 1000 pc may break              
     through the gaseous disk of their host galaxy, and transfer energy          
     and mass into the galactic halo.  The Large Magellanic Cloud contains       
     several supergiant shells, among which LMC\,2 has the most                  
     spectacular filamentary shell structure and the brightest diffuse           
     X-ray emission.  ROSAT PSPC mosaic image of LMC-2 shows excellent           
     correspondence between the optical shell structure and the boundary         
     of the X-ray emission, confirming that the X-ray emission indeed            
     arises within LMC-2.  We propose to use ASCA observations to make           
     spatially resolved spectra in order to determine the physical               
     conditions of the plasma in LMC-2 interior and study the physical           
    structure of LMC-2.
