Storm level needed
Craigavon sits at 54.45N 6.39W in Northern Ireland, United Kingdom. The IGRF-14 centered dipole puts Craigavon at 57.2 degrees geomagnetic latitude, 2.7 degrees closer to the magnetic pole than its map latitude suggests. Craigavon sits at 57.2 degrees geomagnetic. By SWPC's rule the average oval edge is overhead at Kp 5, and aurora is usually visible on the northern horizon at G1 (Kp 5) or less.
"aurora is commonly visible at high latitudes (northern Michigan and Maine)"
The nearest other Glow towns are Lisburn (24 km), Newry (30 km), Antrim (32 km). Lisburn sits 0.0 degrees higher on the dipole and needs the same Kp.
Approximate: SWPC calls its Kp to latitude rule an average, and a centered dipole can differ by a degree from fuller field models. How the storm level is matched
The year in darkness
Every night of 2026 at Craigavon has some civil darkness; the shortest month sample still has 4.7 hours.
