What’s happening with the Sun
A powerful solar event is headed toward Earth, with energized particles streaming from the Sun at high speed. Space weather models warn that this solar storm could interact with our planet’s magnetic field, creating dazzling auroras and, at the same time, causing measurable disruptions to satellite-based communications and GPS accuracy. While such storms can be spectacular for skywatchers, they also pose a practical risk for navigation, aviation, and telecommunications.
Potential auroral displays
As charged solar particles collide with Earth’s atmosphere, they excite molecules that glow in northern and southern skies. Depending on the storm’s intensity and the local magnetic activity, people as far south as mid-latitude regions in some cases may glimpse vibrant green, pink, and purple auroras. For skywatchers, the best viewing conditions will usually be after dusk, in dark, clear skies away from urban light pollution. Check local space weather alerts for real-time aurora forecasts and cloud cover updates.
Likely impacts on satellites and navigation
Geomagnetic storms can disturb the ionosphere, a charged layer of the upper atmosphere essential for satellite communications and GPS signals. During result-driven solar storms, GPS accuracy can degrade, and satellite links used for aviation, maritime, and emergency services may experience brief interruptions or higher levels of noise. Operators of satellites and ground stations monitor these conditions, and many systems have mitigations to reduce risk, but users may still notice occasional delays or positioning errors, particularly during the storm’s peak.
Where to expect effects
Predictions suggest the most noticeable auroras will be seen at higher latitudes, yet strong solar activity can produce unusual appearances in lower latitudes as well. Regions with dark skies and clear weather offer the best chances to observe the phenomenon. Those who rely on GPS for timing, navigation, or logistics should anticipate potential short-term fluctuations and plan for backups where feasible, especially for critical operations.
When to watch and plan
Experts say the storm is likely to deliver auroral displays Monday evening into Tuesday morning, local time. For satellite users, the most significant disruptions are typically forecast for the storm’s peak, which may align with medical or aviation scheduling depending on your latitude. Stay informed with NOAA’s space weather alerts and your local meteorological service for updates on storm strength, expected aurora visibility, and potential satellite impact.
How to stay safe and prepared
Most people won’t be at risk from solar activity itself, but there are practical steps to minimize disruption. Aviation and shipping operators may adjust routes to avoid high-radiation zones and HF radio blackouts. GPS-reliant activities should consider possible signal variability and avoid relying solely on precise positioning for critical missions during peak times. Have backup navigation methods and keep communications channels open with operators who monitor space weather conditions.
What scientists are watching
Researchers continue to refine models of how solar storms interact with Earth’s magnetosphere and ionosphere. Data from satellites orbiting Earth, ground-based magnetometers, and radio observations contribute to forecasts that help authorities anticipate auroras and mitigate disruptions to satellite communications and navigation networks.
Bottom line
Expect dazzling auroras in unusual places and possible satellite and GPS disruptions as a severe solar storm unfolds. While the spectacle is appealing for night-sky enthusiasts, anyone relying on satellite-based services should stay informed through official space weather alerts and plan for potential short-term variations in system performance.
