    PR # 32137                                                                   
     Fast stellar winds from massive stars sweep up the surrounding gas to       
     form bubbles.  The shocked stellar wind, reaching 10$^6-10^7$ K,            
     emits X-rays.  Wind-blown bubbles with well-determined stellar wind         
     parameters and bubble dynamics are ideal locations to study                 
     interactions between stellar winds and the ambient medium.  NGC\,6888       
     is the only bubble confirmed to emit diffuse X-rays.  ROSAT PSPC data       
     cannot determine whether high-temperature components exist in               
     NGC\,6888.  We request ASCA observations of NGC\,6888 in order to           
     determine more accurately the physical condition of its hot interior.       
     The results can place constraints on the heat conduction between the        
     shocked winds and the cold swept-up ambient matter, and allow us to         
    investigate how stellar winds
