Friday the 13th solar storm could bring auroras to 18 US states this weekend
- A moderate geomagnetic storm is predicted to hit Earth's magnetic field, potentially causing auroras visible in up to 18 U.S. states starting this weekend.
- The storm was initially forecasted to start on Saturday but could begin on Friday, with predictions indicating it could reach G3 geomagnetic storm levels.
- Contrary to some reports suggesting a severe G4 storm, experts clarify that the upcoming storm will not be as intense as previously occurred events.
- Geomagnetic storms result from fluctuations in the solar wind, with this storm caused by a co-rotating interaction region triggered by a solar coronal hole.
- Potential impacts of geomagnetic storms include aurora displays, radio blackouts, power infrastructure damage, and satellite disruptions.
- Auroras may be visible in states like Alaska, Montana, North Dakota, and others, as well as in the U.K. and parts of Europe.
- Solar activity has been heightened due to the solar maximum phase, starting in 2024 earlier than expected and likely nearing its end.
- In May 2024, a powerful G5 geomagnetic storm led to widespread auroras and disruptions, showcasing the impact of solar activity on Earth.
