This image is composed of 7 separate images that were captured on August 2, 2011 then "stitched" together to create a single image. On this day the Sun was sporting three active regions with some nice sunspots. The one on the left in this image is AR1263. The center grouping is AR1261 and the right-most region is AR1260. The filament next to the sunspot in AR1260 actually developed during our imaging session.
