How Moon Phases Work at A Coruña's Latitude

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.

Frequently Asked Questions

What is Lunar Coordinated Time (LTC)?
LTC is a proposed Moon-based time standard. Because lunar gravity is weaker (gravitational blueshift) and the Moon's orbital speed is lower (transverse Doppler redshift), Moon clocks run approximately +56.02 µs faster per Earth day than Earth clocks. MoonSync cumulates this offset from J2000.0 (Jan 1, 2000, 12:00 UTC) to display the total LTC lead over UTC at any moment.
Why is the lunar surface temperature so extreme?
The Moon has no atmosphere to distribute or retain heat. In direct sunlight, temperatures reach +127 °C (400 K) at the sub-solar point; on the nightside they fall to −173 °C (100 K) — a 300 °C swing driven purely by the presence or absence of solar radiation. MoonSync estimates temperature using the Stefan–Boltzmann model: T (K) = 400 · sin(altitude)^0.25.
What is a Permanent Shadow Region (PSR)?
PSRs are polar craters on the Moon that have never received direct sunlight, due to the Moon's low axial tilt (1.54°). Temperatures can fall to −230 °C — cold enough to preserve water ice for billions of years. NASA's LCROSS mission (2009) confirmed water ice at the lunar south pole. MoonSync classifies any polar site (|lat| ≥ 87°) with negative solar altitude as a PSR.
How accurate are MoonSync's calculations?
MoonSync uses simplified Keplerian orbital elements and geometric optics suitable for education and illustration — not for navigation. Earth–Moon distance accuracy is ±3,000 km; LTC offset uses NASA's 2023 value of +56.0205 µs/day; phase timing drifts ≈±30 min over a synodic month. For navigation-grade results, consult JPL Horizons or USNO data.
When will the moon rise and set at my location?
MoonSync calculates moonrise and moonset times using your browser's location (or manually entered coordinates). The Moon rises roughly 50 minutes later each day due to its eastward orbital motion. Moonrise/moonset times depend on your latitude, the Moon's declination, and the current lunar phase. MoonSync uses real-time ephemeris data to compute accurate rise/set times and shows whether the Moon is currently above or below your horizon.

Frequently Asked Questions About Moon Data in A Coruña

What is the moon phase tonight in A Coruña?
Tonight's moon phase for A Coruña is displayed in real time on MoonSync. The page loads with A Coruña's coordinates (43.4°, -8.4°) and shows the current moon illumination percentage, lunar age (days since new moon), moonrise and moonset times, and the moon's position above A Coruña's horizon. All calculations run client-side — no location data is sent anywhere.
When is the next full moon visible from A Coruña?
MoonSync's lunar calendar shows the full moon phase progression for any date and location, including A Coruña. Full moons occur approximately every 29.53 days. At 43.4° latitude, full moons near the winter solstice rise at their highest point in A Coruña's sky, while full moons near the summer solstice stay lower on the horizon — this seasonal variation is why winter full moons appear more dramatic from A Coruña.
How does the moon's phase affect stargazing in A Coruña?
Moon phase is the single most important factor for stargazing quality at A Coruña. A full moon (100% illumination) brightens the sky enough to obscure all but the brightest stars and makes deep-sky observation nearly impossible. For the best stargazing in A Coruña, plan sessions during the 7 days around New Moon when illumination is below 15%. Use MoonSync to find the next New Moon date, then use the Twilight Calculator to check when astronomical darkness begins.
Why does moonrise time change each day in A Coruña?
The moon rises approximately 50 minutes later each day as seen from A Coruña because the moon orbits Earth at about 1 km/s, moving approximately 13° eastward per day against the background stars. Since Earth rotates 360° in 24 hours (15°/hour), the extra 13° of rotation takes roughly 50 minutes. This daily delay explains why the moon is sometimes visible in A Coruña's daytime sky and why moonrise can occur at any hour of the day or night.
