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:
Variables
| ω | angular velocity (°/day) |
| A | constant - current set of accepted average values : 14.713 deg/day (± 0.0491) (°/day) |
| B | constant - current set of accepted average values : -2.396 deg/day (± 0.188) (°/day) |
| ϕ | solar latitude (degree) |
| C | constant - current set of accepted average values : -1.787 deg/day (± 0.253) (°/day) |
