Aniya1, and S.Taguchi1 1Univ. of Electro-Communications   A numerical representation of the aurora oval including the position of the SAR arc has been developed as a function of IMF and solar wind velocity.  Our approach is to relate the auroral distribution to the high-latitude potential model which is represented with solar wind parameters.  The obtained model shows dynamic nature of the auroral oval and stable feature of the SAR arc.  Detailed results of the validity of the model for superstorms are presented.  ???????????????????????????????????????????????????????????????????????????????????????????????????????????
