Solar Rotation

Description

Solar rotation is able to vary with latitude because the Sun is composed of a gaseous plasma. The rate of rotation is observed to be fastest at the equator (latitude φ=0 deg), and to decrease as latitude increases. The differential rotation rate is usually described by the equation shown.
A current set of accepted average values is:

A= 14.713 deg/day (± 0.0491) B= -2.396 deg/day (± 0.188) C= -1.787 deg/day (± 0.253)
