Moon Phases Visible from A Coruña

From A Coruña at latitude 43.4°, 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, A Coruña's mid-latitude latitude affects the moon's maximum altitude in the sky. The moon can reach up to 75.2° altitude when crossing the meridian near summer solstice, and only 18.0° near winter solstice. This seasonal variation determines how high the moon appears above A Coruña's horizon and affects lunar photography planning.

A Coruña sits directly on the centerline of the August 12, 2026 total solar eclipse — the longest totality (1 minute 58 seconds) of any major city in the path. The city's Tower of Hercules, a UNESCO World Heritage Roman lighthouse dating from the 1st century, has watched over this Atlantic coastline for nearly 2,000 years and will witness the Moon's shadow sweep across the Bay of Biscay.

Moonrise & Moonset Times at A Coruña

The moon rises approximately 50 minutes later each day as seen from A Coruña. 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 A Coruña's latitude (43.4°), 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 A Coruña using real-time ephemeris data.

At 43.4°N on Spain's northwestern Atlantic coast, A Coruña's sun path is shaped by the Cantabrian Sea: summer sunsets linger past 10 PM over the water, creating extended golden hours that attract photographers to its glass-fronted Paseo Marítimo — the longest seaside promenade in Europe at over 13 km.

Moon Illumination & A Coruña's Dark-Sky Planning

For stargazing and astrophotography in A Coruña, 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 43.4° 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 A Coruña.

Lunar Data Accuracy for A Coruña

MoonSync computes moon phase, illumination, moonrise/moonset times, and lunar age for A Coruña using real-time ephemeris data. Phase illumination is accurate to ±1%. Moonrise and moonset times are calculated from A Coruña's precise coordinates (43.4°, -8.4°) 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.
