New Hampshire · ≈ 52.6° magnetic latitude · needs about Kp 6.8

Northern lights tonight in New Hampshire

New Hampshire sits at about 53° magnetic latitude, so the aurora reaches it from roughly Kp 6.8 — a few nights a year, on G2–G3 storms. The card below reads NOAA's oval, tonight's dark hours, the cloud and the Moon for First Connecticut Lake, Pittsburg right now.

New Hampshire's north tip at Pittsburg is 45° north and 53° magnetic, with the Connecticut Lakes giving open water toward Québec and no town for 60 km — the state's one genuinely dark aurora site, Kp 6.5 and up. The White Mountains are darker than their fame suggests but their northern horizons are peaks; the Auto Road base and the notches give gaps. Umbagog on the Maine line is the flat alternative. Concord and the seacoast need a G3 and see mostly red.

Where to go in New Hampshire

Three sites a photographer would drive to, each with its measured ground darkness from the light pollution atlas and its own verdict for tonight. Coordinates are approximate: a viewpoint, a shore, a car park.

Starting settings if aurora is visible

NOAA's hemispheric power measures activity across the hemisphere, not brightness at your pin. These exposure starting points do not guarantee a sighting; check the local viewing window and sky, then adjust a test photo.
