Intense solar coronal mass ejection will hit the earth between Thursday and Friday

A small coronal mass ejection (CME) directed towards Earth already hit Earth's magnetic field on Wednesday. NOAA's Space Weather Prediction Center (SWPC) predicts that a more powerful Earth-bound CME will strike Thursday-Friday.

The SWPC has already issued geomagnetic storm warnings for a minor geomagnetic storm today, a strong geomagnetic storm on Thursday and a moderate one on Friday.

The impacts were insignificant on Wednesday but could be more significant on Thursday, as a strong geomagnetic storm can trigger fluctuations in the power grid, create satellite irregularities, and degrade radio and GPS signals. The SWPC storm severity scale is 1 to 5.

therefore an impact is to be expected both in space, on the activity of satellites, including geolocation, or a slowdown of satellites in low orbit. Furthermore, the storm could interfere with the electrical systems even on the surface, also leading to the insertion of some safety systems.

Here is more information from spaceweather:

On August 14, an eruption of dark plasma sent a CME towards Earth. On August 15, an exploding magnetic filament launched another CME right behind it. The two CMEs will arrive together on August 18, according to NOAA's latest forecasting model:

This could be a “Cannibal CME” event. In other words, the second CME could overtake and swallow the first, creating a mixture of the two. Cannibal CMEs contain tangled magnetic fields and compressed plasmas that sometimes trigger severe geomagnetic storms.

The Sun is in a very active 11-year solar cycle, called Solar Cycle 25, which began in December 2019.

The peak of the solar cycle is expected in 2025, but even before then its presence will be felt on Earth and around it through the CMEs that will disrupt modern life.
