Stargazing in New Hampshire

True astronomical darkness runs from 11:51 PM to 9:16 AM (9.4 hours) at New Hampshire's central latitude — this is the real window when the sky is darkest.

Cloud cover decides whether you can see anything at all, so check a local forecast before you go. In New Hampshire, skies are usually clearest after a cold front passes, and higher, drier sites tend to beat valleys and coasts. Hourly cloud outlook →

The Moon is Waning Crescent at 9% illumination. Moonlight shouldn't significantly interfere with deep-sky observing tonight. Full Moon details →

• Jupiter — visible in Leo, toward the East (up to 32° altitude).
• Saturn — visible in Cetus, toward the South (up to 48° altitude).
• Mars — visible in Cancer, toward the East-Southeast (up to 46° altitude).

Draconids is active tonight. A minor, unpredictable shower best watched right after nightfall, unlike most showers which peak before dawn. Full calendar →

The ISS is visible to the naked eye as a bright, steady point crossing the sky in a few minutes, usually shortly after dusk or before dawn. Live ISS tracker →

Current planetary Kp is 2.7; New Hampshire's central latitude needs roughly Kp 7.8 for aurora to become visible. Aurora is unlikely from most of the state tonight at current activity levels. Full Aurora forecast →

Darkness and Moon conditions tonight favor deep-sky and Milky Way viewing, assuming clear skies and distance from city lights. This doesn't account for light pollution at your specific spot — a real light-pollution measurement isn't currently available for this location, so use distance from city lights as a practical guide instead. Check Milky Way visibility →

Moonlight is low tonight, which favours the Milky Way and fainter deep-sky objects. 3 planets are realistically observable. Pick a dark site away from city lights and confirm the local cloud forecast before you go.

The White Mountain National Forest, the Kancamagus Highway area and the Pittsburg / Connecticut Lakes region near the Canadian border are the darkest areas.

• White Mountain National Forest — Mountain forest with many dark pull-offs.
• Pittsburg / Connecticut Lakes — Remote northern tip of the state.

The southern tier (Manchester, Nashua), the Lakes Region, the White Mountains and the Great North Woods.

The south is affected by Boston-area glow; the north is very dark.

Visible from the mountains and north in summer.

The Perseids are popular from mountain overlooks.

Late summer and early autumn; winter is clear but very cold.

Easy from anywhere.

Aurora is possible during moderate storms and can be vivid during strong ones. A dark site with a clear northern horizon gives the best chance.

Mountain lakes and covered bridges make classic foregrounds.

Major meteor showers (Quadrantids, Lyrids, Perseids, Geminids), Milky Way core season and any eclipses apply here as they do nationally -- dates shift each year, so check the current calendar.

Mountain weather changes quickly; bring layers even in summer.
