Pleasant Observing Conditions
Pleasant and comfortable observing conditions existed on the morning of August 27th. Blue sky held no clouds, temperature ranged from 71 to 73 degrees, and only light breezes puffed from time to time. In addition, the Sun exhibited an attractive collection of sunspots!
Sunspots were mostly concentrated in the southeastern solar quadrant as shown in the next 9-panel disc mosaic. (Click on these images to enlarge for the best view.)
A few prominences around the limb can also be seen in the following enhanced disc mosaic.
The sunspot cluster in the Sun's southeastern quadrant was quite dramatic. The complex array can be seen in the following 2-panel mosaic. 
Closest to the top is the dual umbra of sunspot 4195. The lower 4195 umbra is split. White areas are regions of energetic emissions including a minor flare to the upper left of 4195. Nearest to the limb below are two umbras that seem to be fenced in by a curved dark filament. The upper umbra is sunspot 4202 and the lower one is 4204. All other complex structure to the upper right of the 4202/4204 filament "corral" is active area 4197. (Enlarge the image to see more detail.) Area 4197 is quite amazing! It features a curved arc with 5 separate umbras, two more umbras to the lower left of the curve, magnetic arcs connecting the two umbra arrays, and some white high energy emissions. Quite a showpiece!
In addition to the nice sunspot array, the southeastern quadrant also featured a prominence and a "filaprom". The transition from prominence to filament showed up nicely near bottom of the next image.
Finally, examine the neighborhood of large sunspot 4191 at full size below. Magnetic arcs seem to swirl around the major umbra like a whirlpool! A smaller split umbra accompanies the larger one on the left. Magnetic arcs connect the two small umbras of sunspot 4200 near the image bottom.
