Rigid and Differential Rotation of the Solar Corona,
Abstract
The rotation of the solar corona has been studied using recurrence properties of the green coronal line (5303A) for the interval 1947-1970. Short-lived coronal activity is found to show the same differential rotation as short-lived photospheric magnetic field features. Long-lived recurrences show rigid rotation in the latitude interval plus or minus 57.5 degrees. It is proposed that at least part of the variability of rotational properties of the solar atmosphere may be understood as a consequence of coexistence of differential and rigid solar rotation.
