The sun was quite active on November 17, 2011, so we decided to put together this 5-panel mosaic of some interesting regions. This image shows some nice prominences, plages, and filaments, as well as a huge filament that spans a good distance of the sun. This great filament measures over 800,000 km from end to end and is one of the biggest things in the entire solar system.
