This Year's Strongest Flare Triggers Radio Blackout In Europe And Africa

There was an X5.1 class flare yesterday (Tuesday) morning--the strongest of the year.  According to UPI, it "triggered radio blackouts on the African and European continents and disrupted high-frequency communication on Earth's sunlit part." The National Oceanic and Atmospheric Administration (NOAA) described the resultant coronal mass ejection as "quite energetic" and stated that it was the "fastest" CME observed so far from the sunspot group region. "It was the latest in a series of other large flares that took place Sunday and Monday," according to the UPI article.
