These bright elements presumably represent the enhanced network resulting from the dispersal of magnetic flux from old active regions, a hypothesis which is consistent with current ideas of coronal hole formation.","","","","","Netherlands","1977-05-01","","English","Journal Article","","","52:2","Journal Name: Sol.
