Waning Gibbous in Aries

Waning Gibbous on . The illuminated surface of the moon is 84% 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 17 August 2027 at 07:29.

Sturgeon Moon before 4 days

Next Full Moon is the Harvest Moon of September 2027 after 25 days on 15 September 2027 at 23:04.

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 ∠1830"

Lunar disc appears visually 3.6% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1830" and ∠1897".

Lunation 341 / 1294

The Moon is 18 days old and navigating from the middle to the last part of the current synodic month. This is lunation 341 of Meeus index or 1294 from Brown series.

Synodic month length 29.32 days

The length of this lunation is 29 days, 7 hours and 36 minutes and it is 1 hour and 19 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 5 hours and 8 minutes shorter than the mean synodic month length. It is 1 hour and 1 minute longer compared to 21st century's shortest synodic month length.

Lunar orbit details for

True anomaly ∠2.6°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠2.6° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠18.2°.

Moon after apogee

5 days since point of apogee on 15 August 2027 at 14:23 in ♑ Capricorn 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 30 August 2027 at 15:36 in ♌ Leo.

Distance to Moon 391 744 km

The Moon is 391 744 km (243 418 mi) away from Earth and getting closer over the next 9 days until the point perigee when Earth-Moon distance is going to be 359 208 km (223 202 mi).

Moon after ascending node

5 days after ascending node on 16 August 2027 at 05:51 in ♒ Aquarius the Moon is positioned north of the ecliptic over the following 8 days until the lunar crosses the ecliptic again from North to South in descending node on 29 August 2027 at 23:01 in ♌ Leo.

Moon before northern standstill

9 days since the last southern standstill on 12 August 2027 at 02:05 in ♐ Sagittarius when the Moon has reached South declination of ∠-27.209° the lunar orbit is extending northward over the next 5 days to face maximum declination of ∠27.172° at the point of next northern standstill on 26 August 2027 at 14:14 in ♊ Gemini.

Draconic month

5 days since the beginning of this draconic month in ♒ Aquarius the Moon is navigating from the beginning to the first part of the lunar cycle.

Syzygy in 10 days

In 10 days on 31 August 2027 at 17:41 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.
