DINOSAURS ROAM THE SUN: "Solar prominence activity has been spectacular for several days now," says Mike Taormina of Palatine, Illinois. "This Brontosaurus-shaped prominence I photographed yesterday is just one example!"
Later, the seething cloud reformed itself into a gigantic gazelle, captured by Charles Tilley of Statesville, North Carolina.
The show continues today, with several lively prominences rising and falling over the sun's limb. If you have a solar telescope, take a look and see what's next in the menagerie.

STORMY HALOS: On April 7th, "the same sky that spawned dark tornados to the north delivered stunning sun halos over our Tampa skies--and moon halos nine hours later," says Florida photographer Martin Zloty. "Can you tell which is which?"
Hint: The sun halo is the one with blue sky.
These halos are caused by ice crystals floating in high cold clouds--probably cirrostratus clouds, which are often found at the advancing edge of storm fronts. Whenever you see a sun or moon halo, be alert also for icy pillars, 'dogs and other strange shapes in the sky.
