Waning Gibbous in Aries

Waning Gibbous on . The illuminated surface of the moon is 81% and getting smaller. The lunar cycle is 19 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 ∠6° of ♈ Aries tropical zodiac sector.

4 days after Full Moon

Previous main lunar phase is the Full Moon before 4 days on 31 July 2080 at 19:13.

Buck Moon before 4 days

Next Full Moon is the Sturgeon Moon of August 2080 after 24 days on 30 August 2080 at 10:41.

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 ∠1823"

Lunar disc appears visually 3.7% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1823" and ∠1892".

Lunation 996 / 1949

The Moon is 19 days old and navigating from the middle to the last part of the current synodic month. This is lunation 996 of Meeus index or 1949 from Brown series.

Synodic month length 29.29 days

The length of this lunation is 29 days, 6 hours and 52 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 52 minutes shorter than the mean synodic month length. It is 17 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit details for

True anomaly ∠357°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠357° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠12°.

Moon after apogee

5 days since point of apogee on 31 July 2080 at 00:49 in ♒ Aquarius 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 14 August 2080 at 15:04 in ♌ Leo.

Distance to Moon 393 155 km

The Moon is 393 155 km (244 295 mi) away from Earth and getting closer over the next 9 days until the point perigee when Earth-Moon distance is going to be 358 080 km (222 501 mi).

Moon in ascending node

Moon is in ascending node in ♈ Aries at 09:26 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 18 August 2080 at 02:15 in ♎ Libra.

Moon before northern standstill

7 days since the last southern standstill on 28 July 2080 at 13:41 in ♐ Sagittarius when the Moon has reached South declination of ∠-28.461° the lunar orbit is extending northward over the next 6 days to face maximum declination of ∠28.549° at the point of next northern standstill on 11 August 2080 at 20:32 in ♊ Gemini.

New draconic month

At 09:26 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 9 days

In 9 days on 15 August 2080 at 08:13 in ♌ Leo 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.
