Sunspot is so large, people are starting to notice it with their naked eyes



"The weather was very cold, -20 degrees Celsius and there was a light mist that made it possible to shoot right at the Sun without any filters," says Strand. "In the foreground you can see the downpipes on my neighbor's house."

To take the picture, Strand set his Nikon D800E digital camera as follows: 510mm/f4.8, ISO 400, 1/6000 sec. Sky watchers who wish to photograph the spot should take note of those settings, but be careful. Even when the sun is dimmed, viewing it through unfiltered optics is every dangerous. One stray beam of magnified sunlight can blind you. Use the digital viewfinder to safely align the camera.
