Moon Phases Visible from London

From London at latitude 51.5°, 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, London's high-latitude latitude affects the moon's maximum altitude in the sky. The moon can reach up to 67.1° altitude when crossing the meridian near summer solstice, and only 9.9° near winter solstice. This seasonal variation determines how high the moon appears above London's horizon and affects lunar photography planning.

Als Heimat des Royal Observatory Greenwich seit 1675 ist London der Geburtsort des Nullmeridians — der 0°-Längenlinie, die die Weltzeit für den gesamten Planeten definiert. Jede Zeitzone der Erde wird relativ zu diesem einzigen Punkt auf einem Hügel mit Blick auf die Themse gemessen, was London zum buchstäblichen Zentrum der globalen Zeitmessung macht.

Moonrise & Moonset Times at London

The moon rises approximately 50 minutes later each day as seen from London. 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 London's latitude (51.5°), 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 London using real-time ephemeris data.

Auf 51,5°N gelegen, prägt Londons extremer saisonaler Tageslichtunterschied von über 8 Stunden zwischen Mittsommer und Mittwinter den Rhythmus der Stadt. Während der Juni-Sonnenwende kann die Dämmerung bis nach 22 Uhr anhalten, während die Dezembertage auf kaum 8 Stunden Sonnenlicht schrumpfen — eine Spanne, die Besucher aus niedrigeren Breitengraden ständig überrascht.

Moon Illumination & London's Dark-Sky Planning

For stargazing and astrophotography in London, 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 51.5° 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 London.

Lunar Data Accuracy for London

MoonSync computes moon phase, illumination, moonrise/moonset times, and lunar age for London using real-time ephemeris data. Phase illumination is accurate to ±1%. Moonrise and moonset times are calculated from London's precise coordinates (51.5°, -0.1°) 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.
