   PR # 21517
    The proposal is aimed to confirm the supernova origin of a galactic  
    object from which the 44Ti 1.157 MeV line emission has been detected 
    by COMPTEL. Two bright ROSAT sources are found inside the COMPTEL    
    angular resolution of this object. It is proposed to use ASCA's SIS  
    spectral capabilities to search for Ka line emission from the        
    hydrogen- or helium-like 44Ti ions. The discovery of 44Ti Ka line    
    emission from the 1.157 MeV line source would prove its supernova    
    origin and therefore would be a first step in solving the long       
    standing problem of the apparent lack of SN in the Galaxy during the 
    last 300 years.
