Today's image shows a complicated area of rays to the east of crater Bronte (named for sisters Charlotte, Emily, and Anne Bronte, and their brother Branwell). The rays trending roughly northeast-southwest originated from Degas, which formed just touching Bronte's rim. The roughly north-south ray (and secondary crater chain) on the right side of the image was probably formed by ejecta that came over the pole from Hokusai.
