   We propose to observe with ASCA the recently discovered SNR G189.6+3.3
   in two regions : the easternmost elongated structure for 30 ks and the
   north rim for 40 ks. ASCA observations will provide a new insight on
   G189.6+3.3 as well as on its relation within the IC 443 complex. Our
   first goal is to examine the structure of temperature, non-equilibrium
   ionization state and abundances to determine if the elongated structure
   belongs to the remnant and if not, to identify its nature. Our second
   goal is to investigate the plasma conditions in G189.6+3.3 and to
   establish if the remnant is physically interacting or not with IC 443.
   The spatially resolved spectroscopic capability of ASCA is required to
   achieve these objectives.
