CME set to spark strong G2 geomagnetic storm, auroras on Earth

Geomagnetic storm today: Over the last few months, the Sun has become increasingly volatile and has been spewing out solar matter such as flares, CMEs, and other particles. This is due to the approaching peak of its 11-year solar cycle, also known as the solar maximum. During this period, solar activity is extremely high and the various planets, including Earth, come in the firing line of the resultant solar storms, geomagnetic storms, and more. Their frequency is likely to increase even more as we approach the solar maximum, which could arrive in 2025. Due to its volatile nature, NASA has several instruments monitoring the Sun's activity.

With their help, NASA, as well as the National Oceanic and Atmospheric Administration (NOAA) have revealed that a CME is approaching Earth rapidly and could hit Earth soon, resulting in a strong geomagnetic storm.

According to a report by spaceweather.com, forecasters at the National Oceanic and Atmospheric Administration (NOAA) and NASA, after carefully studying the data, have shed light on a CME that was released due to a filament erupting on the Earth-facing side of the Sun. Both of their models have predicted that this CME is rapidly approaching Earth, and is expected to hit the planet as soon as tomorrow, September 19. The timing for the impact is still uncertain, with NOAA predicting an early impact, while NASA says it will strike during the late hours of the day.

What's concerning here is the CME's aftermath. As per the report, the CME could spark a G1 or even a stronger G2-class geomagnetic storm on Earth when it hits. For the unaware, while Earth's magnetosphere deflects most solar activity carried by the solar wind, some charged particles seep through. These energetic particles
