Large Solar Flare From Sunspot Is Directed towards Earth
The AR3098 sunspot region has been dormant on the surface of the sun for five days. Solar researchers anticipate a significant chance of flares ever since. Late on September 12, that took place.
Sunspots are regions of the sun with strong magnetic fields that block some heat from reaching the surface. Sunspots appear to be darker and colder.
These solar expulsions may interact with Earth's atmosphere and magnetic field, disrupting radio communications, navigation systems, and power grids.
Flares vary in intensity. A-class flares are the weakest while X-class flares are the strongest. Only M- or X-class flares trigger space weather warnings.
On September 12, AR3098 had a 70% chance of emitting a C-class flare, a 20% chance of emitting an M-class flare, and a 5% chance of emitting an X-class flare, according to SpaceWeatherLive.com.
Later that day, an M-class flare occurred. Alex Young, a solar physicist, tweeted, "FINALLY! AR3098 just unleashed an M1.7 flare at the end of the day on Sept. 12 UTC.
