A severe solar storm this weekend threatens to trigger blackouts, disrupt navigation systems, and knock out high-frequency radios worldwide. It is the first time since January 2005 that the U.S. Space Weather Prediction Center has issued a G4 geomagnetic storm watch.
Key Points
Rare G4 geomagnetic storm watch issued by U.S. Space Weather Prediction Center
Solar storm could disrupt electric grids, navigation systems, and high-frequency radios
Potential for auroras visible in Asia, Europe, and North America
Trans-polar flights may be rerouted to avoid radiation exposure
Pros
Increased awareness of space weather events
Precautionary measures can be taken to minimize disruptions
Cons
Potential for power outages and disruptions to critical systems
Rerouting of trans-polar flights may cause inconvenience
