Image Details:

It took 8 days for sunspot AR 2765 to travel approx. 1.2Mkm across the Sun's surface. Considering the Sun's circumference of 4.38Mkm, this puts the Sun's rotational speed at a little over 29 days at this latitude.
The Sun, being the huge ball if gas that it is, rotates much faster at the poles than it does at the Solar equator.
