Active solar observer and member of the Sydney City Skywatchers , Monty Leventhal, reports viewing gases rising off the edge of the Sun. These gases are called a prominence and move under the influence of magnetic fields.

Monty observes with a special filter on his telescope that shows the Sun in a narrow colour emitted by hydrogen atoms. In ordinary white light the brightness of the rest of the Sun would overwhelm the faint light from the prominence.

Note that it is dangerous to look at the Sun without specialised knowledge and equipment.
