Moon phase and lunation details

1 day after Full Moon

Previous main lunar phase is the Full Moon before 1 day on 29 July 2026 at 14:36.

Moonrise and moonset

Moon rises in the evening and sets in the morning. It is visible to the southwest and it is high in the sky after midnight.

Moon is entering ♒ Aquarius

Moon is passing first ∠0° of ♒ Aquarius tropical zodiac sector.

Apparent angular diameter ∠1826"

Lunar disc appears visually 3.4% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1826" and ∠1890".

Buck Moon before 1 day

Next Full Moon is the Sturgeon Moon of August 2026 after 27 days on 28 August 2026 at 04:18.

Upcoming main Moon phases

Moderate tide

There is medium ocean tide on this date. Sun and Moon gravitational forces are not aligned, but meet at very acute angle, so their combined tidal force is moderate.

Lunation 328 / 1281

The Moon is 16 days old. Earth's natural satellite is moving from the middle to the last part of current synodic month. This is lunation 328 of Meeus index or 1281 from Brown series.

PreviousCurrent lunationNext

Synodic month length 29.33 days

The length of the lunation is 29 days, 7 hours and 53 minutes. It is 1 hour and 57 minutes shorter than the next lunation's length. The lengths of the following synodic months are going to increasing with the true anomaly getting closer to the value it has at the point of New Moon at apogee (∠180°).

Lunation length shorter than mean

The length of the current synodic month is 4 hours and 51 minutes shorter than the mean synodic month length. It is 1 hour and 18 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit position on

True anomaly ∠18°

At the beginning of the lunation cycle the true anomaly is ∠18°. At the beginning of next synodic month the true anomaly is going to be ∠36.5°.

Moon after apogee

5 days after point of apogee on 25 July 2026 at 16:45 in ♐ Sagittarius. The lunar orbit is getting narrow, while the Moon is moving towards the Earth. It will keep this direction over the next 9 days, until the Moon reaches the point of next perigee on 10 August 2026 at 11:18 in ♋ Cancer.

Previous apogeeNext perigee

Distance to Moon 392 486 km

The Moon is 392 486 km (243 879 mi) away from Earth and getting closer over the next 9 days until the point perigee when Earth-Moon distance is going to be 363 288 km (225 737 mi).

Moon in ascending node

Moon is in ascending node in ♒ Aquarius at 11:54 crossing the ecliptic from South to North to meet descending node 12 days later on 13 August 2026 at 09:56 in ♌ Leo.

Previous nodeNext node

New draconic month

At 11:54 the Moon completes the previous draconic month and enters the new one.

Moon after southern standstill

5 days since the previous standstill on 26 July 2026 at 03:56 in ♐ Sagittarius when the Moon has reached South declination of ∠-28.067°, the lunar orbit is extending northward over the next 8 days to face maximum declination of ∠28.107° at the point of next northern standstill on 8 August 2026 at 23:42 in ♊ Gemini.

Previous standstillNext standstill

Syzygy in 12 days

In 12 days on 12 August 2026 at 17:37 in ♌ Leo the Moon is going to be in a New Moon geocentric conjunction with the Sun and thus forming the next Sun-Moon-Earth syzygy alignment.
