Space Weather Prediction Center (SWPC) National Oceanic and Atmospheric Administration (NOAA) The U.S. government today issued a warning and watch. solar storm It can affect the earth’s electrical and communication networks.
of solar storm Either Earth’s magnetism is A large-scale disturbance in the Earth’s magnetosphere that occurs when energy from the solar wind is highly efficiently exchanged in the space environment surrounding the Earth. As NOAA explains on its website, these storms are the result of fluctuations in the solar wind that cause important changes in the electrical currents, plasma, and magnetic fields in Earth’s magnetosphere.
The most severe event -Category G4-, scheduled for November 12th, is in the middle of a series of alerts, including Moderate Watch -G2-. November 11th And powerful surveillance -G3- November 13th. According to the official report released this Tuesday, corona mass emission (CME) activity will occur from November 9th and will continue until the 12th, when the most active and fastest activity of all CMEs occurs.
This particular ejecta was associated with a powerful eruption and was classified as: strong solar flare -R3-, its maximum peak intensity was recorded at 5:04 am on November 11th. Additionally, this extreme solar activity has caused a moderate solar radiation storm -S2- that is currently underway.
SWPC forecasters acknowledged that predicting the impact is complex, as the main ejecta from the latest CME is directed in the following directions: north and beyond the earth’s orbitbut also includes previous coronal mass ejections, which are expected to influence arrival at Earth.
Despite this complexity, there is high confidence that modern CMEs have Earth-oriented components, but only moderate certainty about the exact timing of their arrival.
The Forecast Center emphasized that the actual strength of CME is as follows: It cannot be measured more precisely until it reaches a million miles from Earth.which will then be observed by the Solar Wind Observatory. At that point, forecasters will be able to make the necessary decisions regarding issuing warnings.

The Northern Lights could become visible across much of the northern part of the country, and perhaps as far south as Alabama and Northern California.
This space weather is important results In technology infrastructure such as power transmission, GPS systems, high frequency (HF) radio communications, and satellite communications.
For reference, even if there is mild radio interference -R1-, Slight communication deterioration Frequency radio signals occur on the sunny side, and low frequency navigation signals are temporarily degraded.
SWPC currently maintains the belief that there is a real possibility of reaching G4 levels upon the arrival of CME as the pace of population removal increases, and urges populations and key sectors to: Please be careful Follow us for updates and predictions through our official channels.
