Tonight's Live Forecast
Ohio needs a Kp index of roughly 7+ for visible aurora. Below is tonight's answer, computed from the live Kp reading — updated hourly, explained calmly.

Unlikely in Ohio tonight
The Kp index is currently 3, below the roughly Kp 7 that Ohio needs for visible aurora. Watch for geomagnetic storm alerts — when Kp reaches 7+, tonight's answer changes.

What Ohio Needs for a Display
Ohio aurora nights are strong-storm nights: plan on Kp 7 (G3) for a visible northern-horizon glow, with the Lake Erie shoreline offering the state's best geometry — a flat, dark, water horizon facing exactly the right direction. During severe G4 storms, displays have reached deep into the state. Between events, the lake shore parks are still the spots to bookmark.
On the Kp 7 (G3) view line; Lake Erie's flat northern horizon is the state's advantage. Aurora visibility depends on geomagnetic latitude — which differs from map latitude by up to 15 degrees — so these thresholds come from NOAA SWPC's storm-level view-line estimates, not simple map position. Treat them as odds, not guarantees: at the threshold Kp, expect a glow low on the northern horizon rather than overhead curtains.

When to Look
10 PM – 2 AM local time, centered on midnight. September through March offers the darkest skies. Avoid full-moon nights and city light domes — even 30 minutes of driving makes a real difference.

Aurora visibility in Ohio is driven by the Kp index, so a Kp storm alert is effectively an aurora heads-up. The ResonanceOne app sends free push notifications when the Kp index reaches geomagnetic storm level (Kp 5+) — watch for readings of 7+ to match Ohio's threshold.
To be clear: ResonanceOne is not a dedicated aurora app — no aurora map, no location-based visibility forecast. It tracks the underlying signals (Kp index, solar flares, Schumann Resonance) in one calm Activity Index, and alerts you when they spike.
