Open full aurora dashboardThe auroral oval usually sits well north of mid-latitudes during quiet conditions. A stronger Kp expands that oval southward. For Helsinki, the practical storm threshold is about Kp 3, but a long southward Bz interval matters almost as much as the raw Kp number.
If you are below about 50° latitude, treat Kp 5 as the first serious threshold. Above 60° latitude, even Kp 2-3 can be enough under dark skies.
