Stargazing in Maryland

True astronomical darkness runs from 12:08 AM to 9:41 AM (9.5 hours) at Maryland'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 Maryland, 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 →

Current planetary Kp is 2.7; Maryland'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.

Garrett County in western Maryland, around Deep Creek Lake and state forests, is the darkest area. Assateague Island on the Atlantic coast offers ocean horizons.

• Garrett County / Deep Creek Lake — Mountain county in far western Maryland.
• Assateague Island National Seashore — Barrier island with dark ocean horizons.

The Baltimore-Washington corridor, central Maryland, the western mountains and the Eastern Shore.

Heavy in the central corridor; western Maryland and the lower Eastern Shore are darker.

Visible from Garrett County and Assateague on clear summer nights.

Mountain and beach sites work well; summer humidity can reduce faint meteors.

Autumn for transparency; winter is clear but cold in the mountains.

Easy from anywhere.

Aurora is uncommon but possible during strong geomagnetic storms, usually as a glow low on the northern horizon. Watch the Kp index and find a dark, open view north.

Beaches, wild horses' dune landscapes and mountain lakes make good 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.

Check park after-dark rules and bring bug spray at the coast.
