Sunspot AR2192 28 October 2014

The biggest sunspot in the last 25 years. It has unleashed many strong X-class and M-class solar flares. The most intense of these flares have caused HF radio blackouts and other communication disturbances on the dayside of Earth.

Weather here was very unfavorable for any telescopic high resolution imaging of this enormous sunspot. Here is a quick image I took with telephoto lens during my job time.
