90% chance of seeing Northern Lights in UK tonight

The Met Office has issued a 90% chance alert for viewing the Northern Lights in the UK tonight, particularly in northern Scotland and the Shetland Islands. The best viewing time is expected between 11 PM and midnight. This alert comes as solar wind speeds are predicted to reach over 600 kilometers per second, enhancing the likelihood of aurora sightings. The aurora borealis is typically visible in northern regions but has been seen further south in recent years. The phenomenon is caused by charged particles from the Sun colliding with the Earth's atmosphere. Tonight's conditions are favorable due to ongoing geomagnetic storms, making it a prime opportunity for viewers in the UK.
