Scientists at the NASA Solar Dynamics Observatory posted this video one of the most powerful solar flares Thursday, an X5.4-class flare.

X-class flares are major events that can trigger planet-wide radio blackouts and long-lasting radiation storms.

It appears that right after the large X5.4 flare another slightly lower, X1 flare (5 times smaller) occurred. You can clearly see a wave going across the Sun.

They are still gathering data and the Space Weather Forecast Lab will be having updates available soon.
