Space Weather proposal (pending) : Observed Elongation of LASCO Halo CMEs and its Connection to the Structure of Magnetic Clouds

By Vasyl Yurchyshyn

Solar coronal mass ejections (CMEs) usually exhibits a complex three-part structure which includes a magnetic flux rope and it is thought that the orientation of a halo CME elongation corresponds to the orientation of the flux rope.

Our recent preliminary study showed that for about 64% of CME-ICME events, their orientations do not change significantly (less than 45 deg rotation) while traveling in the heliosphere to the near earth environment. These findings thus strongly motivate the work presented in this proposal.

Specifically, we will further investigate, via data analysis and with reference to relevant models, the correspondence between the elongation of halo CMEs, the structure of magnetic clouds (MCs) and the tilt of the heliospheric current sheet.

To achieve our goal, we will measure:

-the tilt of at least 35+ elongated halos;

-the orientations of the corresponding MCs;

-the local tilt (near a CME source region) of the heliospheric current sheet and

-the magnetic orientation angle in solar active regions.

Erupting flux rope model will be used to fit the observed structure of MCs and to produce synthetic coronagraphic images.
