Live Aurora Outlook
Northern Lights in New York
Tonight's Live Forecast
New York needs a Kp index of roughly 6+ for visible aurora. Below is tonight's answer, computed from the live Kp reading — updated hourly, explained calmly.
Can you see the northern lights in New York tonight?
Close — a small uptick would put it in reach
The Kp index is currently 5, just below New York's approximate threshold of Kp 6. Geomagnetic activity moves in waves, so a substorm could briefly tip the odds — worth a look north if you are already somewhere dark.

What New York Needs for a Display
Upstate New York is on NOAA's Kp 6 view line, and the Adirondack Park — six million acres with true darkness — is where that actually cashes out. A moderate G2 storm can put color on the northern horizon from Tug Hill and the high peaks region; the Thousand Islands and Lake Ontario's eastern shore add flat water horizons. New York City is effectively out of the game short of a historic G4–G5 event.
NOAA's Kp 6 (G2 storm) view line reaches New York; the Adirondacks are the state's aurora country. 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.
Don't Refresh This Page All Winter —
get a Kp alert instead
Aurora visibility in New York 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 6+ to match New York'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.
