This large spot that makes up this active region is typical of many of the current solar cycle; single, large, solitary circular spots with very little activity surrounding them. Fortunately there was a large prominence on the limb to add to the image. Taken with the 100mm PST mod at 1600mm focal length with the DMK31 camera.
