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.

With 2012 nearing its end, it may be a good time to have a quick review of some of the more spectacular events that the Sun produced this year. Though Solar Cycle 24 (SC24) certainly has been weak so far, solar activity was quite interesting at times with the Sun producing some truly amazing events.
