Storm level needed
Douglas, Munster sits at 51.87N 8.44W in Munster, Ireland. The IGRF-14 centered dipole puts Douglas, Munster at 55.0 degrees geomagnetic latitude, 3.1 degrees closer to the magnetic pole than its map latitude suggests. Douglas, Munster sits at 55.0 degrees geomagnetic. By SWPC's rule the average oval edge is overhead at Kp 6, 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 Cork (4 km), Cluain Meala (73 km), Limerick (89 km). Cork 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
