Details:
I got fed up waiting for AR4136 to flare so I thought I would color it to better show the surface flow patterns. I then noticed that the main sunspot seems to be pulsing and sending out circular waves over the surface. I may be imagining it but look closely at the lower major sunspot (white here) and see if you can see it. The video plays at 20 fps and each frame is 30 seconds after the previous so the video plays at 20x30 = 600x real time.
