Astronomers are monitoring an arch-shaped prominence dancing along the limb of the sun. "It is several times wider than Earth," notes Greg Piepol of Rockville, Maryland, who recorded this view through his Coronado SolarMax90:
Michael Buxton of Ocean Beach, California, has made a must-see movie of the prominence. "It was quite large and very pleasing to view as it danced in the chromosphere. The movie shows 1 hour and 45 minutes of action."
Readers with solar telescopes, train your optics on the sun's northwestern limb.
