✦ Synopsis

Extreme ultraviolet spectroheliograms in Mg x (625 ~) and the Lyman continuum (897/~) obtained from OSO-6 are used to determine the differential rotation rate in the solar chromosphere and corona. The equatorial rotation rate agrees with spectroscopic measurements of the photospheric plasma velocity; the variation of rate with latitude is less pronounced than in most other determinations. We cannot discern a variation in the rotation rate between the chromosphere and corona.

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
