Resumen:
We analyze the smallest ´sigmoidal eruption - CME - interplanetary magnetic cloud´ event even observed before. We find: (a) the same magnetic helicity sign and (b) similar magnetic flux values in the coronal source region and associated cloud, and (c) that the magnetic helicity changes, before and after the ejection, in approximately the same amount as the helicity content in the interplanetary cloud. These results stress the importance of complementary solar and interplanetary studies, to achieve a better understanding of the origin of eruptive phenomena.
