Kp bands are magnetic-latitude screening ranges, not probabilities. Cloud, darkness and your view of the horizon still decide whether you can see a display.

What this means for tonight

A stronger auroral expansion can bring a display within view of New Hampshire, often low to the north. Kp is a prompt to check the map and your local sky, not a promise that travelling farther north will produce a sighting.

Solar wind / IMF Bz Β· Fresh Β· observed 14 Oct, 17:11 UTC

NOAA OVATION is a regional activity model. Bz, light pollution, the auroral oval and safe access also matter.

Check the local sky

Mountain weather near Berlin, southern conditions around Manchester and coastal cloud near Portsmouth need separate checks. Use the forecast for your chosen spot and recheck it before leaving; a clear coastal or northern card does not describe the whole state.

Where to look

Choose an open northern horizon with little direct lighting. Mountains, trees and buildings can hide a low display. A familiar accessible viewpoint can be more useful than climbing higher, especially when cloud covers the hills.

Choose your next stop

Open the nearest city forecast and check access to your actual destination. Milan Hill near Berlin is one place to research, but park hours, gates and conditions need a separate check. An aurora alert is not a reason to start an unfamiliar mountain walk after dark.

Aurora forecast questions and answers

Can I see the northern lights in New Hampshire tonight?
It is possible during suitable geomagnetic activity, but you also need darkness and a clear view of the northern sky. Check the local forecast before going out: a storm alert alone cannot tell you whether your part of New Hampshire has a visible display. A faint aurora may appear much subtler than photographs suggest.
Which forecast should I use: Berlin, Manchester or Portsmouth?
Use Berlin for the northern comparison, Manchester for the populated south and Portsmouth for the coast, then open the forecast closest to your viewing spot. These cards do not describe every mountain, valley or stretch of shoreline. Their purpose is to show why one statewide weather reading is not enough.
Is northern New Hampshire always the best place to watch?
No. Being farther north can help, but mountains, trees and cloud may block a low display. A clear, dark northern view closer to Manchester or Portsmouth can be more useful than a long drive into cloudy hills. Compare the actual sky and access at a place you can reach comfortably.
What Kp level is useful for New Hampshire?
Read the guide for your nearest location together with the aurora map, rather than waiting for one number for the entire state. The range is based on magnetic latitude and is only a screening guide. Stronger activity can make checking worthwhile, but clouds, daylight and a blocked horizon can still prevent a view.
Should I head to Milan Hill or a mountain lookout after an alert?
Check official access and conditions first. Milan Hill is near Berlin, but park hours, gates and available services can change with the season. A familiar accessible spot with a clear northern view may be a better choice than a mountain route. Do not start an unfamiliar walk after dark simply because the aurora forecast looks promising.
How can Aurora Hunt help me watch for northern lights in New Hampshire?
Bring local forecasts, cloud maps and aurora alerts for your New Hampshire plans together in Aurora Hunt. Follow the outlook near home or during a visit without refreshing several pages throughout the evening. Download the app before your next clear night so the forecast is ready when you are choosing whether to go out. Download Aurora Hunt
