The real sky, measured for where you stand

Tonight's Sky Over Haikou

Every light on this dome is computed for Haikou and this minute: 1,627 real stars, the five naked eye planets, the Moon with its true phase. The seven classical bodies carry their generation names from the Septenary line, labeled as tradition, never as measurement. Step outside and check it.

At 20 degrees north, the sky differs: the north celestial pole stands 20 degrees above the northern horizon, so every star within 70 degrees of it never sets, and the opposite cap of the sky never rises.

The sky on 4 August 2026

Computed on the server for 12:00 UTC on 4 August 2026, and the same for every reader, because a phase, a sign, a retrograde and an angle to the Sun do not depend on where you stand. The dome above is the part that does, and it is drawn for your own place and minute.
Moon, 4 August 2026
Waning Gibbous
67 percent lit, standing in Aries, 20.5 days old in a cycle of about 29.5 days.
Longest after sunset, 4 August 2026
Venus
About 45 degrees east of the Sun, so it sets roughly 3 hours after the Sun does.
Retrograde, 4 August 2026
Saturn
Apparent backward motion against the stars, read from a dated station table rather than an estimate.

The seven bodies and their signs on 4 August 2026

The sign column is measured: it is the body's ecliptic longitude at 12:00 UTC, and it is the same from every point on Earth. The line column is tradition, held apart on purpose and never presented as a measurement.

The whole of 4 August 2026, in plain words

The same figures written out as sentences, so they can be read without the map, without JavaScript, and without a location.
  • On 4 August 2026 the Moon is a Waning Gibbous, 67 percent lit, standing in Aries.
  • On 4 August 2026 the naked eye planet that stays up longest after sunset is Venus, about 45 degrees east of the Sun; how long it lingers after sunset depends on your latitude, and the dome above answers that.
  • On 4 August 2026 Mercury stands about 19 degrees west of the Sun, so it leads the Sun up and belongs to the hours before dawn; the dome above shows it against your own horizon.
  • On 4 August 2026 Venus stands about 45 degrees east of the Sun, so it follows the Sun down and belongs to the evening; the dome above shows how long it lingers over your own horizon.
  • On 4 August 2026 Mars stands about 47 degrees west of the Sun, so it leads the Sun up and belongs to the hours before dawn; the dome above shows it against your own horizon.
  • On 4 August 2026 Jupiter stands about 5 degrees from the Sun, close enough to be lost in the glare.
  • On 4 August 2026 Saturn stands about 118 degrees west of the Sun, so it leads the Sun up and belongs to the hours before dawn; the dome above shows it against your own horizon.
  • On 4 August 2026 Saturn is retrograde, which means it appears to move backwards against the stars from where we watch.
  • On 4 August 2026 the seven classical bodies stand as follows: the Sun in Leo, the Moon in Aries, Mercury in Cancer, Venus in Virgo, Mars in Gemini, Jupiter in Leo and Saturn in Aries.

Every figure in this section is computed from public domain Meeus algorithms for 12:00 UTC on 4 August 2026, the same anchor the rest of this site uses for a dated sky. Nothing here is hashed from the date, and nothing here depends on where you stand, which is why it can be the same for every reader.

What is measured here, and what is tradition

Two registers, kept apart on purpose, on every surface of this page.
Measured

Star, planet and Moon positions are computed from your coordinates and the clock, to well under a degree. Rise and set times, twilight stages and the Moon's lit fraction are calculated the same way, for your place and minute.

Nothing on this page is hashed from the date. If a number is shown, it was computed, and you can step outside and check it.

Tradition

The zodiac signs used in readings are 30° spans of the year anchored to the equinox. The constellations behind them are unequal star patterns, and the two drifted about 24° apart over the centuries.

Generation names, watcher names and sign meanings are tradition: always labeled as tradition, never presented as measurement.

The registers never blend, and no star is ever for sale

The stars your grandmother saw

The stars above you tonight are the same lights every generation of your line stood under. The reading tells you what the seven bodies passing among them carry for your line today.
