Recent intense solar storms have caused spectacular aurora displays and disrupted satellite and communication systems across the UK and North America. These space weather events, driven by coronal mass ejections from the sun, can have significant impacts on our technology infrastructure. Curious about how these solar storms affect our daily lives? Below, we answer common questions about satellite disruptions, communication risks, and what to expect during these solar events.
-
Are satellite disruptions common during solar storms?
Yes, satellite disruptions are quite common during solar storms, especially when geomagnetic activity reaches high levels. The recent solar storm caused widespread disturbances, affecting GPS signals, satellite communications, and even some space-based navigation systems. These disruptions happen because the charged particles from the sun interfere with the electronic systems onboard satellites.
-
What communication systems are most at risk?
Radio communications, GPS signals, and satellite-based internet services are most at risk during solar storms. High-energy particles can cause signal degradation or loss, especially in high-latitude regions like northern Europe and North America. Power grids and aviation communication systems can also experience interference during intense geomagnetic activity.
-
How long do satellite and communication issues last?
The duration of satellite and communication disruptions depends on the intensity and duration of the solar storm. Minor disturbances may last a few hours, while more severe events can cause issues lasting several days. Currently, experts expect the ongoing storm to impact systems into Thursday, with recovery times varying based on the severity of the geomagnetic activity.
-
Can we predict satellite failures caused by solar activity?
Scientists can forecast solar storms and geomagnetic activity with some accuracy, allowing agencies to prepare for potential disruptions. Space weather prediction centers monitor solar activity and issue alerts when a significant storm is expected. While predictions help mitigate risks, some satellite failures may still occur unexpectedly due to the unpredictable nature of space weather.
-
What can we do to protect satellites and communication systems?
To protect satellites and communication infrastructure, operators can put satellites into safe modes, adjust or delay satellite operations, and strengthen shielding against charged particles. Power companies and communication providers also monitor space weather forecasts closely to minimize the impact of solar storms on their systems.
