Major X5.0 solar flare

Happy New Year to all of our visitors and fans! How do we celebrate that? With a major solar flare of course! The Sun was kind enough to produce some spectacular fireworks yesterday just two hours before UTC midnight. It was a major X5.0 (R3-strong) solar flare that peaked at 21:55 UTC. Sunspot region 3536 is the source of the eruption which is just rotating into view on the east limb. This is actually the return of sunspot region 3514 which produced an X2.8 solar flare during the previous solar rotation.
