    PR # 32144                                                                   
     We propose to observe the young supernova SN 1978K in a search for          
     pulsations from a yet undiscovered pulsar.  This target was                 
     previously observed by ASCA in the Performance Verification phase as        
     part of a pointing at NGC 1313.  This observation was not optimized         
     for pulsar searches in that it had temporal resolution limited to           
     62.5 ms.  (Nonetheless, we have found a statistically interesting           
     periodicity in these data at 4.72 Hz.)  The proposed study will allow       
     us to search for pulsations in the range of periods that are                
     plausible for newly formed neutron stars.  The sensitivity limit will       
     be about $2 \times 10^{38}$ ergs s$^{-1}$.  This observation will           
     yield important additional data on the X-ray light curve of this            
    object whether the source is p
