   We propose to observe the newly-discoverd young supernova remnant, RX
   J0852-4622. The COMTEL detected emission line from 44Ti in the vicinity
   of RX J0852-4622, suggesting RX J0852-4622 to be a very young SNR. 44Ti
   decays into Ca with lifetime of 100 yr. Thus, we can expect a strong
   emission line from Ca. We like to confirm Ca emission lines with ASCA
   follow-up observation. We also propose other two interesting regions:
   central region and southern shell region.
