   The X-ray emission from class I protostars has been detected by ASCA.
   We want to know if the class 0 protostars emitte the hard X-ray. HH 24-
   26 region of L1630(Orion B) is a very young, active star-forming
   region, and HH 24 is one of the class 0 protostar candidates with an
   energetic molecular jet. >From the observation with ASCA, we can
   investigate the nature of plasma of this region and magnetic activity
   of the class 0 protostar.
