Abstract:
We will discuss the structure of the magnetic fields in the super events
on October 28, 29 and November 18 2003 by combining space- (SOHO, TRACE,
RHESSI, ACE) and ground- (BBSO DMG, Halpha) based data. The orientation
of the corresponding magnetic clouds at 1AU will be mapped onto the
relevant active regions with a correction for the angle between the
ecliptic and equatorial planes. This mapping will give us approximate
orientation of the flux rope when it was launched, provided that it was
created in the solar corona and the orientation is preserved during its
propagation through the interplanetary media. We will use these data to
infer the magnetic topology of the source regions and magnetic fields
involved in eruption.
