Largest Sunspot In a Quarter Century Spews Flares

schwit1 writes: The largest sunspot seen in about a quarter century has produced another powerful X-class flare today, the sixth in less than a week. "This was the sixth X-class solar flare from NOAA 2192, a record for the number of X-class flares generated by a single group so far this solar cycle. It was also the fourth X-class flare since last Friday, continuing a period of intense flaring activity. This sunspot group has grown again a bit, and maintains its magnetic complexity. A degradation of the HF radio-communication was observed over South-America, the Caribbean, and West-Africa." The last sentence is referring to some radio communications blackouts that have occurred in these areas because of the flares.
