A CME EXPANDING IN BOTH THE RADIAL AND LATERAL DIRECTIONS
-
摘要: 1980年5月5日CME事件的外环具有很强的角膨胀,但内环角膨胀很小;角膨胀使外环前沿变坦、冕流弯曲并移位。与在同一太阳区域内相继发生的5月6日事件相比,两者的径向运动特征在时间域内各异,在空间域内却是相似的。

Abstract: The angular expansion of the 5 May 1980 event is large in the outer loop,but insignificant in the inner loop; the expansion made the outer front flattering,and the streamer moving and bending. In comparison with the event in successionoccurring in the same solar region on the next day, the characteristics of theradial motion are different in the time domain, but similar in the space domain.Physical implications of above features are discussed in the paper.-
