Dynamics of polar plumes observed during the total solar eclipse of August 1, 2008
Abstract
We study dynamics of polar plumes observed during the 2008 eclipse from three ground-based sites and the Hinode satellite. The speed of apparent upward propagation, as inferred from the changes of brightness within each plume, is found to lie in the range from 30 to 100 km s-1. Some white-light plumes located in polar coronal holes were identified with their X-ray counterparts observed by the Hinode satellite, which showed almost the same speed.
