Stargazing in Delaware

True astronomical darkness runs from 12:03 AM to 9:35 AM (9.5 hours) at Delaware'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 Delaware, 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 53° 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; Delaware's central latitude needs roughly Kp 9.0 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.

Trap Pond State Park in southern Delaware is known for astronomy events. Cape Henlopen State Park offers ocean horizons, and rural Sussex County farmland is darker than the north.

• Trap Pond State Park — Southern Delaware park popular for astronomy nights.
• Cape Henlopen State Park — Coastal views east over the Atlantic.

New Castle County (Wilmington, brightest), central Kent County (Dover) and rural Sussex County with the beaches.

The north is heavily lit; beach towns add summer glow. Inland Sussex is the darkest area.

Visible from southern Delaware in summer on clear, low-humidity nights.

Flat terrain gives wide horizons; coastal haze can reduce faint meteors.

Autumn and winter for transparency; summer humidity softens views.

Easy from anywhere; ocean horizons are good for low planets and moonrise.

Aurora is rare this far south and needs an exceptional geomagnetic storm. It usually appears as a faint red or pink glow low in the north, often clearer on camera than to the eye.

Beaches and lighthouses make good foregrounds for moonrise and Milky Way.

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.

Check park hours and bring bug spray for coastal marshes.
