Northern lights tonight in Ohio

Ohio sits at about 51° magnetic latitude, so the aurora reaches it from roughly Kp 7.8 — rare: G4 storms, once or twice a year at solar maximum. The card below reads NOAA's oval, tonight's dark hours, the cloud and the Moon for Marblehead, Lake Erie right now.

Ohio's whole aurora chance is Lake Erie: the north shore gives a 50 km water horizon toward Canada, and on a Kp 7.5–8 (G3–G4) night the arc stands high over it with Cleveland and Toledo behind you. Marblehead and the islands are the darkest stretch; Geneva and Headlands Beach are the eastern shore's public parks with parking that stays open. Ohio is at about 51° magnetic latitude, so a strong G3 is the threshold and G4 puts colour overhead — the May 2024 storm was photographed from Columbus and Cincinnati, which sit a degree further south and normally see nothing.
