Space Weather Prediction Center (SWPC) National Oceanic and Atmospheric Administration (NOAA) Today the United States issued an alert and watch for Solar storm Which could affect electricity and communications networks on Earth.
the Solar storms also It is terrestrial magnetism A major disturbance of the Earth’s magnetosphere occurs when there is an extremely efficient exchange of energy from the solar wind into the space environment surrounding our planet. As the National Oceanic and Atmospheric Administration (NOAA) explains on the website, these storms are the result of changes in the solar wind that produce significant changes in currents, plasma and fields in the Earth’s magnetosphere.
The most severe event – Category G4 – scheduled to occur on November 12, falls amid a series of alerts that include a moderate watch – G2 – for November 11 -G3-‘s powerful control November 13. According to the official report published on Tuesday, coronal mass ejection (CMEs) activity has occurred since November 9 and will continue until the 12th, the day when the most active and fastest of all CMEs will occur.
This particular ejection was associated with a powerful explosion, classified as a volcanic eruption Strong solar flare -R3-, whose peak intensity was recorded at 5:04 a.m. on November 11. In addition, this intense solar activity has created a mid-level solar radiation storm – S2 -, which is currently in progress.
Forecasters at SWPC acknowledged that forecasting the impact is complex, as the dominant ejecta from the latest CME is directed towards North and Before Earth’s orbitalthough previous coronal mass ejections are also in the mix and are expected to affect Earth arrivals.
Despite this complexity, confidence that the most recent CME will have an Earth-directed component is high, although the exact timing of its arrival has only a moderate level of certainty.
The Prediction Center confirmed that the true density of continuing medical education It cannot be determined with greater precision until it reaches a distance of a million miles from Earth.Then it will be monitored by solar wind observatories. At this point forecasters will be able to make any necessary decisions about issuing warnings.

The aurora borealis could become visible over much of the northern part of the country, and possibly as far south as Alabama or northern California.
This could be space weather Important consequences In technological infrastructure, including electrical power transmission, positioning systems, high frequency (HF) radio communications and satellite communications.
For reference, even a simple radio interruption -R1-, implies a Slight deterioration in communications High-frequency radio signals on the sunlit side and a short degradation of low-frequency navigation signals.
For now, SWPC maintains the belief that there is real potential to reach G4 levels in time for CME as the pace of expulsion progresses, urging the population and key sectors to Be attentive And follow up on the latest information and expectations through its official channels.
