The Sun wanted to let us know there was action going on in other places in the Solar System besides Mars.

A huge, dark-colored filament stretched across nearly half the solar face on August 5th.

Estimates are this filament was about 800,000 km in length! Wow!

Paul Andrew took six images to create a composite, full image of the Sun, and below is an 11-panel mosaic by Leonard Mercer from Malta to show the surrounding region with the main sunspots 1535, 1538, 1540 present.
