Sunspot AR1678

A large sunspot is developing on the sun with a chance of X-flares (the most powerful kind) over the next 24 hours. Like the logarithmic Richter scale for earthquakes, X-class flares are 10x (or more) more powerful than M-class, which are 10x more powerful than C-class, ... 

Of course I went out and tried to grab an image with some welding goggles strapped over my camera with a 200mm telephoto lens.  I turned the exposure down to 1/4000s F5.6.


In the image above you can just see it near the edge at about 5 o'clock (it might help to adjust your display's brightness/contrast to see it).  Below the sun's image is rotated 180 degrees, the storm is the set of three dark spots close to the center of the image.


Of course there are much better images online.  Here is the report from space weather.


And below is a dramatic image from space.com.
