Abstract
A study on the differences of rotation properties, based on the lifetime of coronal features, has been performed for the period 1972–1974. The short-lived component of the green corona associated with solar activity is differentially rotating, while long-lived coronal features persisting more than one synodic rotation period, show little or no differential rotation. These two components coexist at a same latitude within a wide latitude range at least in one of the solar hemispheres.
