    PR # 31077                                                                   
     Because of its proximity, SN1987A is providing us with a unique oppor       
     tunity  to study an SNR in their very early phase of evolution.  ROSA       
     T detected  soft X-rays from the SN in 1991-1992 observations, whose        
     origin is  probably the shock formed by the colliding ejecta and the        
     wind remnant  of the progenitor. Increase of the radio flux being obs       
     erved since 1990  to date is probably of the same origin. ASCA observ       
     ed the SN in 1993  and 1994, and obtained flux upper limit of ~5E-14        
     erg/cm2 sec.   Given the distribution of the circumstellar matter aro       
     und the SN  revealed by the HST, increase of the X-ray luminosity is        
     expected as  the ejecta expands. Therefore, we propose continued moni       
     toring of the  SN.  Search for the emission from the pulsar in higher       
     energy  range is also importa
