's upper atmosphere. The material in that CME is likely to impact Earth on April 14, according to SpaceWeather.Sunspots are dark regions on the surface of the Sun. They are caused by intense magnetic flux from the Sun's interior, according to the. These spots are temporary and can last anywhere from hours to months.
The idea of a"dead" sunspot is more poetic than scientific, said Philip Judge, a solar physicist at the High Altitude Observatory at the National Center for Atmospheric Research , but the convection of the Sun breaks these spots apart, leaving in their wake magnetically-disturbed bits of quiet solar surface.
C-class flares are fairly common and rarely cause any impacts on Earth directly. Sometimes, as with today's eruption, solar flares can trigger coronal mass ejections, which are huge eruptions of plasma and magnetic fields from the Sun that travel outward into space at millions of miles per hour.
