Waning Gibbous in Aries

Waning Gibbous on . The illuminated surface of the moon is 88% and getting smaller. The lunar cycle is 18 days old.

Moonrise and moonset

The 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 phase and lunation details

Moon is entering ♈ Aries

Moon is passing first ∠1° of ♈ Aries tropical zodiac sector.

3 days after Full Moon

Previous main lunar phase is the Full Moon before 3 days on 9 August 2025 at 07:55.

Sturgeon Moon before 3 days

Next Full Moon is the Harvest Moon of September 2025 after 26 days on 7 September 2025 at 18:09.

Neap tide

There is low ocean tide on this date. Sun and Moon gravitational forces are not aligned, but meet at big angle, so their combined tidal force is weak.

Apparent angular diameter ∠1943"

Lunar disc appears visually 2.6% wider than solar disc. Moon and Sun apparent angular diameters are ∠1943" and ∠1894".

Lunation 316 / 1269

The Moon is 18 days old and navigating from the middle to the last part of the current synodic month. This is lunation 316 of Meeus index or 1269 from Brown series.

Synodic month length 29.45 days

The length of this lunation is 29 days, 10 hours and 55 minutes and it is 2 hours and 53 minutes shorter than the upcoming lunation's length. The lengths of the following synodic months are going to increase with the lunar orbit 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 1 hour and 49 minutes shorter than the mean synodic month length. It is 4 hours and 20 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit details for

True anomaly ∠60.5°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠60.5° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠93°.

Moon before perigee

10 days since point of apogee on 1 August 2025 at 20:37 in ♏ Scorpio the lunar orbit is getting narrow while the Moon is moving towards the Earth. It will keep this direction over the next 2 days until the Moon reaches the point of next perigee on 14 August 2025 at 18:01 in ♈ Aries.

Distance to Moon 368 873 km

The Moon is 368 873 km (229 207 mi) away from Earth and getting closer over the next 2 days until the point perigee when Earth-Moon distance is going to be 369 287 km (229 464 mi).

Moon after ascending node

1 day after ascending node on 11 August 2025 at 14:53 in ♓ Pisces the Moon is positioned north of the ecliptic over the following 12 days until the lunar crosses the ecliptic again from North to South in descending node on 24 August 2025 at 15:41 in ♍ Virgo.

Moon before northern standstill

6 days since the last southern standstill on 5 August 2025 at 13:37 in ♐ Sagittarius when the Moon has reached South declination of ∠-28.534° the lunar orbit is extending northward over the next 6 days to face maximum declination of ∠28.585° at the point of next northern standstill on 18 August 2025 at 15:59 in ♊ Gemini.

Draconic month

1 day since the beginning of this draconic month in ♓ Pisces the Moon is navigating from the beginning to the first part of the lunar cycle.

Syzygy in 10 days

In 10 days on 23 August 2025 at 06:06 in ♍ Virgo 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.
