Details:
Animation of the evolution of Sunspot AR 4478, which is impressive to me. GIF animation file.The evolution of this group, AR 4478, is interesting especially the movement of the middle spots toward the front spot. Moreover note that the main spots rotate in two days. Transformation shown here was made from two images taken on June 27 and June 28. TMB 13 cm refractor.
