Warnings that the Earth will be exposed to solar storms within hours
<p style=";text-align:left;direction:ltr">Arabia Weather - Although seeing the aurora borealis is usually considered associated with natural phenomena such as these, the Space Weather Prediction Center (SWPC), which is affiliated with the National Oceanic and Atmospheric Administration (NOAA), warned on Sunday of a large magnetic storm approaching Earth. .</p><p style=";text-align:left;direction:ltr"> The SWPC issued a geomagnetic storm watch alert Saturday evening, just as a coronal mass ejection was on track to reach Earth through Monday. The agency indicated that geomagnetic storms may reach G2 “moderate” and G3 “strong” levels.</p><p style=";text-align:left;direction:ltr"> <strong><u>However, the SWPC warned on Sunday that the storm had reached "severe" G4 conditions, according to The Hill.</u></strong></p><p style=";text-align:left;direction:ltr"></p><p style=";text-align:left;direction:ltr"></p><blockquote class="twitter-tweet" style=";text-align:left;direction:ltr"><p lang="en" style=";text-align:left;direction:ltr"> The 23 March CME arrived at around 24/1411 UTC.

Geomagnetic storms can also affect navigation, communications, and radio signals. Typically, G1 storms have minor impacts on the power grid, satellite operations, and the movement of migratory animals. As for very large storms, they may disrupt satellites, communications networks, and electrical distribution.</p><p style=";text-align:left;direction:ltr"></p><h3 style=";text-align:left;direction:ltr"> <u><strong>Solstice of the solar cycle</strong></u></h3><p style=";text-align:left;direction:ltr"> As for the severity of the storm, SWPC indicated that geomagnetic storms reaching G4 conditions have been reported, and are expected to continue for hours to come.</p><p style=";text-align:left;direction:ltr"> NOAA notes that approaching the peak is accompanied by fluctuations in the arctic and antarctic solar cycle, which typically occur over a period of 11 to 25 years.</p><p style=";text-align:left;direction:ltr"> During this period, a variety of space weather events can occur, including geomagnetic storms and the northern lights that can reach Earth.</p><p style=";text-align:left;direction:ltr"></p><p style=";text-align:left;direction:ltr"></p><p style=";text-align:left;direction:ltr"> Read also:</p><p style=";text-align:left;direction:ltr"> <a href="https://www.arabiaweather.com/ar/content/%D9%86%D8%A7%D8%B3%D8%A7-%D8%AA... is developing a system to predict solar storms half an hour before they hit Earth</a></p><p style=";text-align:left;direction:ltr"> <a href="https://www.arabiaweather.com/ar/content/%D8%A7%D9%84%D8%AF%D9%88%D8%B1%... current solar cycle will reach its peak in 2025 and is expected to be one of the strongest solar cycles</a></p><p style=";text-align:left;direction:ltr"></p><p style=";text-align:left;direction:ltr"></p>
