As previously reported, sunspot AR3038 is currently facing Earth. It implies that it might direct a solar flare toward us. Sunspot evolution can be seen in video taken on Sunday by NASA’s Solar Dynamics Observatory, which has been twisting and contorting all day.
Sunspots are black spots on the surface of the sun that are linked to powerful radiation bursts. Because they are cooler than other areas of the sun’s surface, they seem dark.
Because they develop over regions where the magnetic fields of the sun are very strong—so strong that they prevent some of the heat produced inside the sun from reaching its surface—sunspots are relatively chilly.

These disorganised magnetic fields occasionally spontaneously rearrange. When that occurs, a solar flare—a rapid explosion of light and radiation—is ejected from the sun.
AR3038 is the name of the sunspot that has been expanding in size recently. Video taken on Sunday by NASA’s Solar Dynamics Observatory demonstrates the sunspot’s twisting and contorting evolution during the previous day or so.
“Sunspot AR3038 was significant yesterday. It’s big now, “reads the website SpaceWeather.com. “In just 24 hours, the rapidly expanding sunspot has doubled in size.”
Solar flares that are powerful enough to impair radio communication networks and navigational systems on Earth. People who work in the maritime or aviation industries, among others, may experience issues as a result.
But it’s important to remember that an M-class flare wouldn’t likely be all that disruptive. Although M-class solar flares are the second-strongest kind, they often only result in mild radio blackouts. The M9 flare, the strongest in the M-class, has the potential to disrupt low-frequency navigation signals and cut out radio communication for tens of minutes in afflicted parts of Earth. There are also many of M-class flares.
