Solar rotation

The sunspots have kept their pattern but clearly moved showing that the sun is rotating on its axis. It turns out that because the Sun is not solid, the matter round the equator is able to rotate faster than that at the poles. This must result in some shear. Amidst the complications, it is going to take about 28 days for these sunspots to rotate all the way round the Sun, if they survive that long. So the higher double spot should be visible for the next 8 or 9 days.
