The solar flare that hit the sun on Wednesday night is expected to last about five minutes, NASA said on Thursday.
It is also expected to cause auroras across the world, which could be seen in many places.
NASA said the sunspot was in its final stage of activity.
It was the fourth flare in as many days, and the third solar flare since the U.S. and Japan began deploying flares in July.
The first solar flare hit the earth on Sept. 25.
NASA has issued a warning for the U, S, and Japan and warned that the flare will be a strong reminder of the dangers of global warming and pollution, which is why the government of Japan is considering a ban on the use of fossil fuels.
