Abstract
Magnetic helicity (MH) has been recognized as a useful tool to study the link between active regions (ARs) and magnetic clouds (MCs). In this work, we compare the MH and flux of the MC of October 18–19, 1995, and its associated AR. We compute both quantities and we find that the AR flux is one order of magnitude larger than in the MC, while the coronal MH is lower after an ejection linked to a long duration event and comparable to the MC helicity. We conclude that the MH in the interplanetary flux rope comes from the coronal one.
