Waning Gibbous in Aries

Waning Gibbous on . The illuminated surface of the moon is 85% 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 in ♈ Aries

Moon is passing about ∠15° of ♈ Aries tropical zodiac sector.

4 days after Full Moon

Previous main lunar phase is the Full Moon before 4 days on 18 August 2054 at 09:22.

Sturgeon Moon before 4 days

Next Full Moon is the Harvest Moon of September 2054 after 25 days on 17 September 2054 at 01:41.

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 ∠1801"

Lunar disc appears visually 5.2% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1801" and ∠1897".

Lunation 675 / 1628

The Moon is 18 days old and navigating from the middle to the last part of the current synodic month. This is lunation 675 of Meeus index or 1628 from Brown series.

Synodic month length 29.31 days

The length of this lunation is 29 days, 7 hours and 30 minutes and it is 1 hour and 1 minute 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 5 hours and 14 minutes shorter than the mean synodic month length. It is 55 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit details for

True anomaly ∠352.3°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠352.3° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠7.4°.

Moon after apogee

4 days since point of apogee on 18 August 2054 at 10:18 in ♒ Aquarius the lunar orbit is getting narrow while the Moon is moving towards the Earth. It will keep this direction over the next 10 days until the Moon reaches the point of next perigee on 1 September 2054 at 14:49 in ♌ Leo.

Distance to Moon 398 002 km

The Moon is 398 002 km (247 307 mi) away from Earth and getting closer over the next 10 days until the point perigee when Earth-Moon distance is going to be 357 587 km (222 194 mi).

Moon after descending node

3 days after descending node on 18 August 2054 at 14:57 in ♒ Aquarius the Moon is positioned south of the ecliptic over the following 9 days until the lunar crosses the ecliptic again from South to North in ascending node on 1 September 2054 at 07:18 in ♌ Leo.

Moon before northern standstill

8 days since the last southern standstill on 14 August 2054 at 09:17 in ♑ Capricorn when the Moon has reached South declination of ∠-19.120° the lunar orbit is extending northward over the next 6 days to face maximum declination of ∠19.122° at the point of next northern standstill on 28 August 2054 at 21:36 in ♋ Cancer.

Draconic month

17 days since the beginning of this draconic month in ♌ Leo the Moon is navigating from the second to the final part of the lunar cycle.

Syzygy in 10 days

In 10 days on 2 September 2054 at 01:18 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.
