This image of the giant sunspot AR 2192 was submitted by David Arditti and David comments as follows: "The features I find striking here are the linear streakiness seeming to emanate from a point W (celestial) of the group, manifested in its upper part, and the slightly lighter bridge running right across the main umbra.  I used to think sunspots were only bi-tonal, but they are not.

Full details are on the image.
