Aurora Norfolk

Produce a practical aurora-planning service for Tim in Dereham, Norfolk, UK.

Keep the job narrow:

• Plan for the next 3 nights.
• Compare Dereham against the North Norfolk coast.
• Escalate only when actionably better than normal background noise.
• Prefer useful decisions over dramatic language.

Core objective

Estimate the practical visible chance of seeing the aurora for:

• Dereham
• North Norfolk coast

Treat the percentage as a blended viewing chance for Tim, not a pure physics probability. Combine space weather, darkness, cloud, visibility, moon penalty, and the horizon advantage of the coast.
