Forecasters expect the worst solar storm to hit sometime around Friday (July 22) at 8 p.m. EDT (July 23 at 0000 GMT) and into the early morning hours of Saturday (July 23). During this time, a complete aura Coronal mass ejectionor CME Earth’s magnetic field. Forecasts indicate that twilight It may be visible much farther from the poles than at normal latitudes.
The cause of this space weather was observed on Thursday (July 21), according to a permit (Opens in a new tab) From the National Oceanic and Atmospheric Administration (NOAA) Space Weather Prediction Center. Coronal Ejected Masses are bursts of charged particles that are ejected from sun atmosphereor the corona. When these particles interact with the Earth’s magnetic field, they can create spectacular auroras, but they can also wreak havoc on electrical networks or Spacecraft operations disrupted and communications via satellite.

Spaceweather.com reports (Opens in a new tab) The next space weather storms were caused by an explosion in sunspot AR3060, which produced a solar glow. Images produced by NOAA’s onboard solar ultraviolet imager GOES-16 The weather satellite shows a large glow emanating from above the sunequator.
In North America, the storm can bring twilights as far south as Illinois or Oregon, while in the United Kingdom it may be visible from northern Scotland. In addition, radio propagation can be affected at high latitudes, including as far south as New York and Idaho in the United States and northern regions of the United Kingdom. Some migratory animals can be affected, due to the fact that some animals use the Earth’s magnetic field for navigation.
According to NOAA Climate forecast (Opens in a new tab)the storm will approach G1 (minor) and G2 (moderate) levels.
This means that a solar storm can affect electrical infrastructure at high latitudes, possibly causing damage to transformers if prolonged periods of high intensity storms occur. Spacecraft in orbit may also experience changes in drag and may require ground controllers to make changes in direction.
The current storm comes as the sun’s activity continues to increase as part of a regular 11-year solar cycle. After a few years of the sun’s lull, regular flares and flares are becoming more frequent before the peak of this solar cycle, which is expected to occur in 2025.
