SpaceWeather.com | SOLAR SURPRISE - prominence of magnificent proportions

Even during the deepest solar minimum in a century, the sun has the capacity for surprise. Larry Alvarez got one yesterday when he bent over the eyepiece of his solar telescope in Flower Mound, Texas. "I thought it would be just another day with a vanilla-wafer solar disk, but I was in for a blazing shock when I checked out the edge of the sun," he says. "There was a huge worm popping out of the apple--a prominence of magnificent proportions!" Here is what he saw:

"What a doozy," he says. "I watched the prominence for more than two hours and got some really nice shots." He's working on a video now--stay tuned for that.

Realtime images from the Solar and Heliospheric Observatory indicate that the prominence remains active. Readers with solar telescopes should take a look. It's no longer a surprise, but still a doozy.
