11th Nov Sun

11th Nov. Mostly cloudy today but I managed to find a small blue gap to take a couple of pics of the sunspots. Both images are single exposures with Canon 550d attached to a 81 mm refractor, herschel wedge at 540 nm. The prominent sunspot group is AR3141, the largest part of which I measured at 65,000 km across. Other sunspot groups are small and some have disappeared. Thanks for viewing.
