This multi-flame picture shows you the progress of Annular solar eclipse on May 21, 2012 captured with an H-alpha solar telescope.
You can chase that various structures on solar photosphere of active regions and dark filaments are hidden behind the moon one after another, and appeared again.
Unfortunately I could detect no large-scaled prominences in solar rim in that day, but a small filament-like prominence connected to a dark filament can be seen in northeast rim.
These images are pseudo-color processed for original ones captured with monochrome mode.
