Evolution of spicules at the solar limb (2/2)
Hinode Broadband Filter Imager
Temporal evolution of spicules in the northern polar coronal hole as observed by the Broadband Filter Imager onboard the Japanese Hinode satellite on 2007 November 7. The observations were taken through a Ca II H filter at 396.85 nm. Spicules in coronal holes are longer than elsewhere. A radial gradient filter was applied to enhance the intensity of the spicules above the solar limb.
