Waning Gibbous in Aries

Waning Gibbous on . Illuminated surface of the Moon is 92% 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 ∠13° of ♈ Aries tropical zodiac sector.

2 days after Full Moon

Previous main lunar phase is the Full Moon before 2 days on 30 August 2061 at 22:18.

Sturgeon Moon before 2 days

Next Full Moon is the Harvest Moon of September 2061 after 26 days on 29 September 2061 at 09:32.

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 ∠1922"

Lunar disc appears visually 1% wider than solar disc. Moon and Sun apparent angular diameters are ∠1922" and ∠1902".

Lunation 762 / 1715

The Moon is 17 days old and navigating from the middle to the last part of the current synodic month. This is lunation 762 of Meeus index or 1715 from Brown series.

Synodic month length 29.46 days

The length of this lunation is 29 days, 10 hours and 58 minutes and it is 3 hours and 6 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 46 minutes shorter than the mean synodic month length. It is 4 hours and 23 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit details for

True anomaly ∠53.7°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠53.7° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠84.5°.

Moon before perigee

9 days since point of apogee on 23 August 2061 at 20:28 in ♐ Sagittarius the lunar orbit is getting narrow while the Moon is moving towards the Earth. It will keep this direction over the next 3 days until the Moon reaches the point of next perigee on 6 September 2061 at 10:37 in ♊ Gemini.

Distance to Moon 372 923 km

The Moon is 372 923 km (231 724 mi) away from Earth and getting closer over the next 3 days until the point perigee when Earth-Moon distance is going to be 369 805 km (229 786 mi).

Moon in ascending node

Moon is in ascending node in ♈ Aries at 08:31 crossing the ecliptic from South to North. Lunar position remains north of if for the upcoming 12 days until Moon's next descending node later on 15 September 2061 at 08:16 in ♎ Libra.

Moon before northern standstill

7 days since the last southern standstill on 25 August 2061 at 17:13 in ♐ Sagittarius when the Moon has reached South declination of ∠-28.503° the lunar orbit is extending northward over the next 5 days to face maximum declination of ∠28.571° at the point of next northern standstill on 8 September 2061 at 02:43 in ♋ Cancer.

New draconic month

At 08:31 in the point ot ascending node the Moon is completing the last draconic month and is entering a new one while the lunar orbit is crossing the ecliptic from South to North.

Syzygy in 11 days

In 11 days on 13 September 2061 at 20:37 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.
