It caused a brief radio blackout over the Pacific.
Solar scientists had been observing a sunspot that grew to four times the size of our planet and then let out a solar flare estimated to be 18 million degrees Fahrenheit earlier this week,Solar flares occur when regions on the sun's surface become highly magnetized, preventing the normal convection process. This cools down the surface temperature in comparison to other regions and is visible from the Earth as a darker patch called a sunspot.
Looking at its activity, scientists were certain that it would give off a solar flare - when a sunspot sends out large amounts of radiation, if not a coronal mass ejection, the phenomenon where it sends out highly charged particles as well. On September 12, AR3098, while facing the Earth, did send out a big flare which a solar astronomer tweeted about.
FINALLY! AR3098 just released an M1.7 flare at the end of the day on Sept. 12 UTC. An nice impulsive event seen in SDO 131 showing plasma greater than 10 million Kelvin. Hot hot! ☀️🥵🔥🤩 The radio blackout is over the Pacific.
