Will you get real darkness tonight?
At your latitude and this time of year, the Sun never drops 18° below the horizon. Expect a persistent twilight glow all night — deep-sky observing will be limited.

Every sun event, in order
The full ladder from tonight's sunset through tomorrow's sunrise, with what each angle actually means for what you'll see and photograph.
Practical
Golden and blue hour tonight
The two windows every photographer cares about — with the actual clock times for your location.
Golden hour (evening)
21:44 → 22:29
The Sun sits between about 6° above the horizon and the horizon itself. Long, warm shadows; side-lit faces; the classic landscape window.
Blue hour (evening)
22:29 → 22:59
The sky glows deep cobalt while street lights and skylines still hold detail. The single best window for cityscapes.

Educational
The seven Sun angles that shape a day
Sunrise and sunset are just two moments in a smooth arc. What actually determines what you can see or shoot is how far the Sun sits above or below the horizon.
Geometry
Solar declination & noon altitude
The Sun's declination — how far it sits above or below the celestial equator — is what actually drives the seasons. Today it is +22.1°. From your latitude of 59.9°, that puts the noon Sun at an altitude of about 52.2° above the horizon.
A 1.80 m person at solar noon today casts a shadow roughly 1.40 m long. The lower the Sun climbs, the longer every shadow gets — the practical reason winter photographs look so directional.
On the calendar
Next seasonal turning point
The next September equinox is in 73 days — Sep 23 2026. Equinoxes reset day and night to ~12 hours everywhere on Earth; solstices mark the Sun's extreme north or south points, and the year's longest or shortest days.
Why it matters
Why twilight is where astronomy actually happens
For casual observers, the day is neatly split into "day" and "night". For anyone who cares about the sky, the interesting bit is the transition — the roughly two-hour ladder between sunset and true darkness (and again before sunrise). Every one of those steps opens up a different set of objects.
The first stars appear during civil twilight, when the Sun is still only a few degrees below the horizon. By nautical twilight, the horizon is just visible against the sea, which is exactly what mariners historically used to take star sights. By astronomical twilight, the sky is dark enough that only the very faintest deep-sky objects — distant galaxies, the outer arms of the Milky Way — remain hidden by residual glow.
Once the Sun drops past −18°, the sky is officially astronomically dark. This is the state professional observatories, astrophotographers and deep-sky observers care about. At latitudes above roughly 48° in mid-summer the Sun never gets that low, which is why Scandinavia, Scotland and Alaska have "white nights" — a persistent twilight instead of true dark.
The photographer's calendar is different. Golden hour (Sun 0°–6° above the horizon) delivers warm, directional light. Blue hour (Sun 4°–8° below the horizon) is when the sky glows deep cobalt while artificial lights still hold detail — the single most reliable window for cityscapes and architectural work.
