Waning Gibbous in Aries

Waning Gibbous on . Illuminated surface of the Moon is 99% and getting smaller. Lunar cycle is 16 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 ∠16° of ♈ Aries tropical zodiac sector.

1 day after Full Moon

Previous main lunar phase is the Full Moon before 1 day on 24 September 2075 at 10:31.

Harvest Moon before 1 day

Next Full Moon is the Hunter Moon of October 2075 after 28 days on 23 October 2075 at 22:49.

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 ∠1868"

Lunar disc appears visually 2.4% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1868" and ∠1914".

Lunation 936 / 1889

The Moon is 16 days old and navigating from the middle to the last part of the current synodic month. This is lunation 936 of Meeus index or 1889 from Brown series.

Synodic month length 29.53 days

The length of this lunation is 29 days, 12 hours and 41 minutes and it is 49 minutes longer than the upcoming lunation's length. The lengths of the following synodic months are going to decrease with the lunar orbit true anomaly getting closer to the value it has at the point of New Moon at perigee (∠0° or ∠360°).

Lunation length shorter than mean

The length of the current synodic month is 3 minutes shorter than the mean synodic month length. It is 6 hours and 6 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit details for

True anomaly ∠251.8°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠251.8° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠287.7°.

Moon after perigee

5 days since point of perigee on 20 September 2075 at 11:42 in ♒ Aquarius the lunar orbit is getting widen while the Moon is moving away from the Earth. It will keep this direction over the next 7 days until the Moon reaches the point of next apogee on 2 October 2075 at 14:34 in ♋ Cancer.

Distance to Moon 383 735 km

The Moon is 383 735 km (238 442 mi) away from Earth and getting further over the next 7 days until the point apogee when Earth-Moon distance is going to be 404 168 km (251 138 mi).

Moon after descending node

6 days after descending node on 18 September 2075 at 19:47 in ♑ Capricorn the Moon is positioned south of the ecliptic over the following 6 days until the lunar crosses the ecliptic again from South to North in ascending node on 2 October 2075 at 05:26 in ♋ Cancer.

Moon after southern standstill

6 days since the last southern standstill on 18 September 2075 at 20:04 in ♑ Capricorn when the Moon has reached South declination of ∠-22.947° the lunar orbit is extending northward over the next 6 days to face maximum declination of ∠23.070° at the point of next northern standstill on 2 October 2075 at 08:38 in ♋ Cancer.

Draconic month

20 days since the beginning of this draconic month in ♋ Cancer the Moon is navigating from the second to the final part of the lunar cycle.

Syzygy in 14 days

In 14 days on 9 October 2075 at 23:43 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.
