Co-evolution of long-lived coronal structures and photospheric flow fields
Abstract
Large-scale flows in the vicinity of filaments, coronal holes and active regions are investigated. We identify sets of each over the year of past year using the Heliophysics Events Knowledgebase (HEK). Surface velocities are extracted from a set of HMI data cubes using a spectral optical flow method that sample the structures disk passage. We then investigate the co-evolution of the flow patterns and coronal structures as seen by AIA.
