Summary
The Northern Lights, known for their bright displays, appeared in the UK after increased solar activity. The lights were visible as far south as southern England, but sightings are expected to decrease as solar activity lessens. Different colors of the lights are caused by particles from the Sun colliding with gases in Earth's atmosphere.
Key Facts
- The Northern Lights appeared in the UK due to increased solar activity.
- Sightings reached as far south as southern England.
- Solar eruptions send energy toward Earth, influencing aurora sightings.
- The Met Office suggests a possibility of the aurora appearing in northern Scotland.
- The color of the aurora depends on the type of gas the solar particles hit.
- Green is the most common aurora color, caused by oxygen collisions.
- Red auroras occur during strong geomagnetic storms and involve oxygen high in the atmosphere.
- Purple auroras occur when solar particles hit nitrogen, and blue is the rarest, happening lower in the atmosphere with nitrogen collisions.
