Here's the first X-class solar flare of 2015, which erupted on March 11th. Here's the good part: it was so powerful it caused radio blackouts in many parts of the globe. According to NASA, it was an X2 flare: an explosion on the sun's surface that's twice as intense as the already huge and uncommon X1 class. It's bigger than the X1.8 flare from December 2014, but definitely a lot smaller than the record-holding X-28+ eruption that happened in 2003. The event scrambled the ionosphere for around 15 minutes, keeping a lot of radio stations off the air for the whole duration.
