Watch the Sun Trigger an ‘Extremely Rare’ Coronal Mass Ejection and Two Fiery Filaments (Video)

The sun is far from calm.

Yesterday, December 17, the sun drew an “extremely rare” face down coronal mass ejection (CME) – a large plume of plasma and magnetic field.

According to NASA’s Space Weather Database of Notifications, Knowledge, and Information (DONKI)the ER (“extremely rare”) CME recorded an estimated speed of approximately 1,964 miles per second (3,161 km/s!). The flare occurred from the far side of the Sun and has no Earth-directed component. Slower CMEs often take two to three days to arrive whereas if this CME had been directed towards Earth, it would have arrived in less than approximately 18 hours.

“BOOM! Big and very fast full-halo CME in LASCO images this afternoon,” aurora and storm chaser Jure Atanackov wrote in a post. post on X.

BOOM! Large and very fast full halo CME in LASCO images this afternoon. Quickly, most of it cleared the C2 field of vision in less than an hour. The culprit is once again an active region on the other side, probably in the southern hemisphere, near the central meridian. Wow! pic.twitter.com/HaEFcioOQyDecember 17, 2024

This is the fourth CME on the far side in 10 days, hinting at a very active hidden sunspot, yet to rotate, according to Spaceweather.com. We should expect the explosive culprit to spin toward Earth next week.

But the super-fast CME wasn’t the only impressive flare from our star yesterday. Two earlier CMEs erupted during fiery solar filament eruptions on the southeast flank.

Solar filaments are vast clouds of ionized gas above the solar surface. When they become unstable, they either fall back onto the sun or erupt into space, projecting a CME into space. When Earth is in the crosshairs of such eruptions, it can trigger geomagnetic storms – disturbances in Earth’s atmosphere. magnetosphere. Although all three eruptions released CMEs, none are expected to be directed toward Earth.

“Two very photogenic plasma flares from the eastern edge of the Sun this morning! Neither are directed toward Earth,” solar astrophysicist Ryan French wrote in a statement. post on.

“The second coronal mass ejection in particular shows a beautiful structure during its eruption!” The French continued.
