| 摘 要： | 根据ACE/ULEIS卫星数据,确定了2007-05—2010-01太阳活动极小期内的3个独立富3He太阳高能粒子(SEP)事件,并结合STEREO双星对相同事件的观测数据,研究了事件中电子的经向分布特征.结果表明:由耀斑引起的3个独立SEP事件,电子的经向分布宽度可达到130°.计算表明,携带电子传播的日面波传播速度差异显著,电子的此类经向分布很可能是由于其在日面横向扩散所致.当观测点磁力线足点位于耀斑源区东侧时,电子的日面扩散速度更快.

| Abstract: | In this paper,three independent 3He-rich solar energetic particle (SEP) events during the solar minimum from May 2007 to January 2010 were identified using ACE/ULEIS data.The observations of the twin satellites,STEREO-A and B,indicate that the longitudinal distribution of these energetic electrons originated from the minor flare induced SEP events might be extended to about 130 degree.On the assumption that the heliographic transportation accounts for the longitudinal distribution,calculations show that,here exists a magnificent difference in the longitude transport speed of the electron carrying waves,and these electrons moves faster to east than to west from the active particle source. |
