'Dead sunspot' launches ball of plasma toward Earth
Live Science ^ | 04/12/2022 | Stephanie Pappas

The explosion comes courtesy of a dead sunspot called AR2987.... The sunspot explosion released loads of energy in the form of radiation, which also led to a coronal mass ejection (CME) — explosive balls of solar material — both of which could spur more intense northern lights in Earth's upper atmosphere. The material in that CME is likely to impact Earth on April 14...

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 (NCAR), but the convection of the sun breaks these spots apart, leaving in their wake magnetically-disturbed bits of quiet solar surface.

"Occasionally," Judge wrote Live Science in an email, "sunspots can 'restart,' with more magnetism appearing later (days, weeks) at the same region, as if a weakness was made in the convection zone, or as if there is an unstable region under the surface that is particularly good at generating magnetic fields beneath."

Whatever the future of AR2987, the sunspot let out a C-class solar flare at 5:21 Universal Time Monday (April 11). Such flares happen when the plasma and magnetic fields above the sunspot give way under stress; they accelerate outward, Judge said, because they would run into dense material if they went downward toward the sun's interior.

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. C-class solar flares rarely trigger CMEs, according to SpaceWeatherLive(opens in new tab), and when they do, the CMEs are usually slow and weak

A true geek would spit on the ground any time that movie was mentioned and curse Verhoeven roundly for it.

There’s a little black spot on the sun today.

They’ll have to readjust satellites.
Auroras will be seen further south.
It’s a moderate storm according to space weather.

I still can’t wrap my brain around the fact that the sun has been in existence for billions of years without burning out......
