A fairly good sky today enabled me to take some images of the Sun around noon. The first image shows the sunspots at 540 nm - there are lots of small spots at the moment. The second and third images show the NW and SW sectors at 656 nm (Ha) wavelength - line the images up with the first picture (N up, W to right). All are single exposures with a Canon 550d camera.
