摘要：

We follow the evolution and activity of the reversed polarity AR 7912 using multi-wavelength observations. We find that the presence of high shear increased by flux emergence led to the occurrence of a long-duration eruptive flare on 14 October 1995, which was manifested in the SXR corona by an arcade of expanding sigmoidal loops. A twisted magnetic cloud was observed at I AU between October 18-20. We propose that it was ejected from this reversed polarity AR, and it was associated with the expanding sigmoids. (C) 2002 COSPAR.
