   The Galactic center Molecular Flare is a feature which thought to be an
   evidence for a burst of star formation in the recent past. This
   contains hundreds or thousands of expanding molecular shells, which may
   be formed by interaction with supernova remnants (SNRs). We propose
   deep observations of this Molecular Flare with ASCA satellite to find
   SNRs hidden behind severe interstellar absorption toward the Galactic
   center. Since SNRs in high density medium may have high electron
   temperature (several keV), ASCA is the most suitable instrument for the
   purpose. The data will provide us the information on the star formation
   history in our Galactic nucleus, and will advance our understandings on
   the interaction between SNR and molecular cloud.
