    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.
