WHAT GOES AROUND COMES AROUND. Here are two fascinating animations showing the movement and changes in size of Sunspot AR2665-2670 for the periods 05-18 July and 01-14 August that have been derived from the SOHO/HMI Daily Sun images published by www.spaceweather.com. The first is a sequential time-lapse which shows the two traverses of AR2665-2670 recently visible on the earth-facing side of the Sun one after the other. The second, which is even more interesting, compares AR4665 with 4670 when each was at the same longitude on the two successive traverses. This highlights not only the decrease in size and complexity on the second traverse but also that its latitude was significantly further to the south! It must also be quite unusual for a solo, prominent and persistent sunspot to be so clearly visible for two earth facing traverses close to a solar minimum?
