According to space scientists, a powerful geomagnetic storm is moving toward Earth.

 

Space weather experts predict that a powerful geomagnetic storm brought on by the sun could affect Earth later this week.

  • Following recent explosions on the sun that have produced powerful solar flares and several "coronal mass ejections," which could hit the planet on Thursday, the National Oceanic and Atmospheric Administration's Space Weather Prediction Center on Wednesday issued a geomagnetic storm watch.
  • "A major disturbance of Earth's magnetosphere that occurs when there is a particularly efficient interchange of energy from the solar wind into the space environment around Earth," according to NOAA, is what a geomagnetic storm is.
  • The greatest storms caused by these circumstances are linked to solar coronal mass ejections (CMEs), in which a billion tonnes or so of solar plasma with an embedded magnetic field reach Earth.
  • However, there is a risk that the anticipated storm could intensify to a rating of 3 on the geomagnetic storm severity scale, even if most of this week's disturbances are anticipated to have little to no effect.

  • The advent of the geomagnetic storm also implies that on Thursday, viewers in Iowa may be able to see the northern lights.
  • The auroras "could be observed over the far Northeast, through the far upper Midwest, across areas of the north-central states, and perhaps over the northwest," according to the official space forecast.
  • Although auroras are regular, some sky watchers are hoping for a more intense display due to the possibility of several coronal mass ejections colliding, or "cannibal coronal mass ejections," which is a celestial phenomenon.

According to Fox Weather's Andrew Wulfeck, in July, the northern lights were "so vivid that photographers photographed the colourful show even in the centre of Seattle, where light pollution generally mutes vision."

Tomorrow, the "Cannibal" coronal mass ejection from the "black plasma plume" will strike Earth (Aug. 18)

  • On Thursday, August 18, a "cannibal" coronal mass ejection that was formed from a solar eruption of "black plasma" will sideswipe the Earth and trigger a powerful G3 geomagnetic storm.
  • The coronal mass ejection (CME), or explosive jets of solar material, was created by the "dark plasma explosion," which was first noticed by solar astronomers on Sunday (Aug. 14) as it erupted from a sunspot on the sun's surface at a speed of about 1.3 million mph (2.1 million km/h) (opens in new tab). Then, on Monday (15th August), another CME was released from the sun as a result of the collapse of a massive magnetic filament.
Sunspots are regions on the surface of the sun where strong magnetic fields caused by the movement of electrical charges kink before abruptly snapping. The energy that is released as a result causes solar flares or coronal mass ejections, which are solar material plumes, to be launched. The collapse of unstable solar filaments, which are enormous, suspended tubes of electrified gas (or plasma) that weave their way through the sun's atmosphere based on the whims of the star's magnetic field, is another method that CMEs might be generated.
