Details:
This is 10 minutes of AR4526 at right and AR4529 at left. Both sunspots are pulsing with umbral flashes and AR4526 shows a well defined light bridge cutting across it. Amazing how much action there is in 10 minutes. The animation is anchored on the AR4526 sunspot and if you check the limb you can see how much the Sun rotates in 10 minutes.
Playback is 750x real time.
