Waning Gibbous in Aries

Waning Gibbous on . Illuminated surface of the Moon is 94% and getting smaller. Lunar cycle is 17 days old.

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.

Upcoming main moon phases

Main moon phases of the following lunar cycle.

Moon phase and lunation details

Moon in ♈ Aries

Moon is passing about ∠17° of ♈ Aries tropical zodiac sector.

2 days after Full Moon

Previous main lunar phase is the Full Moon before 2 days on 7 September 2063 at 20:53.

Harvest Moon before 2 days

Next Full Moon is the Hunter Moon of October 2063 after 27 days on 7 October 2063 at 13:27.

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 ∠1793"

Lunar disc appears visually 6.1% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1793" and ∠1906".

Lunation 787 / 1740

The Moon is 17 days old and navigating from the middle to the last part of the current synodic month. This is lunation 787 of Meeus index or 1740 from Brown series.

Synodic month length 29.34 days

The length of this lunation is 29 days, 8 hours and 4 minutes and it is 1 hour and 21 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 4 hours and 40 minutes shorter than the mean synodic month length. It is 1 hour and 29 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit details for

True anomaly ∠358.9°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠358.9° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠14.3°.

Moon after apogee

3 days since point of apogee on 6 September 2063 at 18:12 in ♒ Aquarius the lunar orbit is getting narrow while the Moon is moving towards the Earth. It will keep this direction over the next 11 days until the Moon reaches the point of next perigee on 21 September 2063 at 13:02 in ♍ Virgo.

Distance to Moon 399 694 km

The Moon is 399 694 km (248 358 mi) away from Earth and getting closer over the next 11 days until the point perigee when Earth-Moon distance is going to be 358 430 km (222 718 mi).

Moon after ascending node

3 days after ascending node on 6 September 2063 at 22:09 in ♒ Aquarius the Moon is positioned north of the ecliptic over the following 10 days until the lunar crosses the ecliptic again from North to South in descending node on 20 September 2063 at 16:51 in ♌ Leo.

Moon before northern standstill

9 days since the last southern standstill on 1 September 2063 at 05:30 in ♐ Sagittarius when the Moon has reached South declination of ∠-28.251° the lunar orbit is extending northward over the next 5 days to face maximum declination of ∠28.212° at the point of next northern standstill on 15 September 2063 at 22:42 in ♊ Gemini.

Draconic month

3 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 11 days

In 11 days on 22 September 2063 at 09:21 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.
