Waning Gibbous in Aries

Waning Gibbous on . The illuminated surface of the moon is 98% and getting smaller. The lunar cycle is 16 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.

1 day after Full Moon

Previous main lunar phase is the Full Moon before 1 day on 11 September 2079 at 05:36.

Harvest Moon before 1 day

Next Full Moon is the Hunter Moon of October 2079 after 28 days on 10 October 2079 at 17:23.

Moderate tide

There is medium ocean tide on this date. Sun and Moon gravitational forces are not aligned, but meet at very acute angle, so their combined tidal force is moderate.

Apparent angular diameter ∠1887"

Lunar disc appears visually 1% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1887" and ∠1907".

Lunation 985 / 1938

The Moon is 16 days old and navigating from the middle to the last part of the current synodic month. This is lunation 985 of Meeus index or 1938 from Brown series.

Synodic month length 29.46 days

The length of this lunation is 29 days, 11 hours and 3 minutes and it is 3 hours and 11 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 41 minutes shorter than the mean synodic month length. It is 4 hours and 28 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit details for

True anomaly ∠50.5°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠50.5° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠80.4°.

Moon before perigee

8 days since point of apogee on 4 September 2079 at 08:27 in ♐ Sagittarius the lunar orbit is getting narrow while the Moon is moving towards the Earth. It will keep this direction over the next 5 days until the Moon reaches the point of next perigee on 18 September 2079 at 08:26 in ♊ Gemini.

Distance to Moon 379 827 km

The Moon is 379 827 km (236 014 mi) away from Earth and getting closer over the next 5 days until the point perigee when Earth-Moon distance is going to be 369 896 km (229 843 mi).

Moon before ascending node

13 days after descending node on 30 August 2079 at 09:11 in ♎ Libra the Moon is positioned south of the ecliptic over the following day until the lunar crosses the ecliptic again from South to North in ascending node on 13 September 2079 at 17:20 in ♈ Aries.

Moon before northern standstill

7 days since the last southern standstill on 5 September 2079 at 06:20 in ♑ Capricorn when the Moon has reached South declination of ∠-28.246° the lunar orbit is extending northward over the next 6 days to face maximum declination of ∠28.319° at the point of next northern standstill on 18 September 2079 at 20:00 in ♊ Gemini.

Draconic month

25 days since the beginning of this draconic month in ♈ Aries the Moon is navigating from the second to the final part of the lunar cycle.

Syzygy in 12 days

In 12 days on 25 September 2079 at 04:06 in ♎ Libra 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.
