Moon Phases Visible from New York

From New York at latitude 40.7°, the moon's appearance follows the same 29.53-day synodic cycle visible worldwide — all 8 phases from New Moon through Full Moon and back. However, New York's mid-latitude latitude affects the moon's maximum altitude in the sky. The moon can reach up to 77.9° altitude when crossing the meridian near summer solstice, and only 20.7° near winter solstice. This seasonal variation determines how high the moon appears above New York's horizon and affects lunar photography planning.

Zweimal im Jahr säumen Menschenmengen Manhattans Ost-West-Straßen, um 'Manhattanhenge' zu erleben — den Moment, in dem die untergehende Sonne perfekt mit dem Straßengitter des Stadtteils ausgerichtet ist und einen goldenen Schein durch die Betonschluchten wirft. Der Astrophysiker Neil deGrasse Tyson prägte den Begriff als Direktor des Hayden Planetariums, das seit 1935 New Yorks Tor zum Kosmos ist.

Moonrise & Moonset Times at New York

The moon rises approximately 50 minutes later each day as seen from New York. This daily delay occurs because the moon orbits Earth eastward at about 1 km/s, moving roughly 13° per day against the background stars. At New York's latitude (40.7°), the moon's rise and set positions along the horizon shift seasonally — rising further north in summer and further south in winter. MoonSync calculates exact moonrise and moonset times for New York using real-time ephemeris data.

Auf 40,7°N erreicht New Yorks längster Tag zur Sommersonnenwende 15 Stunden und 5 Minuten. Zum Vergleich: Chicago auf 41,9°N gewinnt 8 zusätzliche Minuten Tageslicht — ein winziger Unterschied, der jedoch beim Timing von Manhattanhenge und dem goldenen Fenster, auf das Fotografen angewiesen sind, sofort spürbar ist.

Moon Illumination & New York's Dark-Sky Planning

For stargazing and astrophotography in New York, moon illumination percentage is the critical number. A Full Moon (100% illuminated) washes out all but the brightest stars and makes deep-sky observation nearly impossible. The 7 days around New Moon (0-15% illumination) provide the best dark-sky window. At 40.7° latitude, combine moon phase with the Twilight Calculator to find nights when both astronomical darkness and minimal moonlight coincide — these 'astrophotographer's golden hours' occur roughly once per month at New York.

Lunar Data Accuracy for New York

MoonSync computes moon phase, illumination, moonrise/moonset times, and lunar age for New York using real-time ephemeris data. Phase illumination is accurate to ±1%. Moonrise and moonset times are calculated from New York's precise coordinates (40.7°, -74.0°) and corrected for atmospheric refraction. The Keplerian orbital model used achieves timing accuracy of approximately ±30 minutes over a synodic month. For sub-minute lunar event timing, consult the USNO Phases of the Moon data service.
