Image Details
Caption: Figure 4.
White light eclipse image from 2001 June 21 observed from Angola by members of the Úpice observatory, using a siderostat with an off-axis configuration and a 19/1875 mm lens. The image was composed from eight exposures taken on Kodak Echtachrome 100 S professional slide film, which was then scanned. The scanned image was processed by M. Druckmüller. The circles highlight examples of vortex rings. There is also an abundance of nested loops all around the Sun, the most prominent groups noted by arrows at the south pole and in the southwest. The rectangle highlights a region of turbulence.
