BEHOLD, “THE BEAST”: Around the world, astronomers are monitoring a massive prominence curling over the sun’s northeastern limb. David Wilson of Inverness, Scotland, calls it “The Beast”:

“This is 3 hours of the giant prominence as seen from my backyard solar observatory,” says Wilson. “It looks to me like some huge 4-legged beast shuffling along.”
Prominences are clouds of hydrogen held above the surface of the sun by magnetic fields. The shuffling of the Beast is a sign of magnetic instability and may herald a collapse or magnificent eruption. Photo-op, anyone? Monitoring is encouraged on July 13th.
