The rotation of the solar corona has been studied using recurrence properties of the green coronal line (5303 A,) 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
The differential rotation of the solar corona has been analyzed using as the input data the brightness of the coronal green line Fe XIV 530.3 nm for more than five activity cycles. It is found that the character of rotation of the solar corona changes during the activity cycle. Approximately at the
Long-lived brightness structures in the solar electron corona persist over many solar rotation periods and permit an observational determination of coronal magnetic tracer rotation as a ftmction of latitude and height in the solar atmosphere. For observations over 1964-1976 spanning solar cycle 20,
