What time does the sun rise in Londen today?

Today's sunrise and sunset times for Londen are calculated using your device's location or the coordinates you enter. The times depend on Londen's latitude (51.5°) and the current date. Solar Insight Pro uses the USNO algorithm accurate to ±1 minute. Enter Londen as your location above and select today's date to see the exact sunrise, sunset, solar noon, golden hour, and blue hour times.

When is golden hour in Londen?

Golden hour at Londen occurs during the first hour after sunrise and the last hour before sunset, when the sun sits between −4° and 6° above the horizon. At Londen's latitude (51.5°), golden hour lasts approximately 40–70 minutes. During summer months, the longer twilight at this latitude extends the golden hour window compared to equatorial locations. Open the Photography Mode tab to see countdown timers for the next golden hour and blue hour windows.

How does Londen's latitude affect daylight hours?

Londen at latitude 51.5° experiences significant seasonal variation in daylight. Summer days reach approximately 16.4h of daylight at the solstice, while winter days drop to approximately 16.4h — a 0.0h difference between seasons. The sun's maximum altitude ranges from 61.9° in summer to 15.1° in winter. This high-latitude pattern is why Londen has such pronounced seasonal changes in sunrise and sunset times compared to locations near the equator.

How accurate are sunrise times for Londen?

Sunrise and sunset calculations for Londen use the Jean Meeus Chapter 25 solar position algorithm, verified against the USNO Astronomical Almanac. Accuracy is ±1 minute for dates between 1901–2099. The algorithm accounts for atmospheric refraction (34 arcminutes at the horizon) and uses Londen's precise coordinates (51.5°, -0.1°). For sub-second astrometric accuracy, consult the USNO data service directly. — Solar Insight Pro, fastool.io

How Solar Calculations Work at Londen's Latitude

Latitude & Daylight at Londen

Londen sits at latitude 51.5°. At this latitude, daylight varies from approximately 16.4h in summer (solstice) to 16.4h in winter — a seasonal swing of 0.0h. The sun reaches a maximum altitude of 61.9° at summer solstice and a minimum of 15.1° at winter solstice. This high-latitude profile is what shapes Londen's unique sunrise, sunset, and golden hour patterns year-round.

Golden Hour Photography at Londen

Golden hour at Londen occurs when the sun sits between −4° and 6° above the horizon, producing soft, warm, directional light ideal for portrait and landscape photography. At Londen's latitude, morning golden hour typically starts in the 1–2 hours after sunrise and lasts approximately 40–70 minutes. Evening golden hour mirrors this before sunset. The longer twilight at this latitude gives photographers more time to capture the 'magic hour' compared to equatorial locations where the sun sets more steeply.

UV Exposure & Sun Safety at Londen

UV radiation at Londen peaks when the sun is highest in the sky — around solar noon. At 51.5° latitude, peak UV levels vary significantly by season: summer months see UV indices of 4–6 (moderate), while winter months typically register 0–1 (very low). The World Health Organization recommends sun protection when UV index exceeds 3. At Londen's latitude, this threshold is exceeded for approximately 4–6 months per year, making sun awareness a year-round consideration for outdoor workers and athletes.

How We Calculate Solar Data for Londen

All solar calculations for Londen use the Jean Meeus Chapter 25 solar position algorithm with bisection iteration, accurate to ±1 minute for dates between 1901–2099. Sunrise and sunset times define the moment the upper limb of the sun appears on the horizon, accounting for atmospheric refraction. Daily data is calculated client-side from Londen's coordinates (51.5°, -0.1°) — zero server processing means your location data never leaves your device.
