The best of ... 2014!


In its New Year's letter for 2014, the Sun promised great solar activity to come. True to its word, sunspot numbers reached a new monthly high in February 2014, probably indicating the maximum of the ongoing solar cycle. Throughout the year, this increased sunspot activity was accompanied by plenty of strong flares, big sunspot groups and geomagnetic unrest.

The solar hotshots of 2013!


During 2013, long stretches of solar inactivity alternated with brief spurts of high flaring activity levels. The periods of solar calm featured numerous filament and prominence eruptions, with so many spectacular events they could easily fill this review. There were 12 X-class solar flares, almost as many as 2011 and 2012 combined. Yet, only 5 sunspot regions were responsible for these extreme explosions on the Sun, and most of them took place during the latter part of 2013.

The fairest of them all... (2012)
