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 ∠23° of ♈ Aries tropical zodiac sector.

2 days after Full Moon

Previous main lunar phase is the Full Moon before 2 days on 9 September 2033 at 02:20.

Harvest Moon before 2 days

Next Full Moon is the Hunter Moon of October 2033 after 26 days on 8 October 2033 at 10:58.

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 ∠1972"

Lunar disc appears visually 3.4% wider than solar disc. Moon and Sun apparent angular diameters are ∠1972" and ∠1906".

Lunation 416 / 1369

The Moon is 17 days old and navigating from the middle to the last part of the current synodic month. This is lunation 416 of Meeus index or 1369 from Brown series.

Synodic month length 29.67 days

The length of this lunation is 29 days, 16 hours and 1 minute and it is 1 hour and 49 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 longer than mean

The length of the current synodic month is 3 hours and 16 minutes longer than the mean synodic month length. It is 3 hours and 47 minutes shorter compared to 21st century's longest synodic month length.

Lunar orbit details for

True anomaly ∠140.6°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠140.6° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠166.6°.

Moon after perigee

1 day since point of perigee on 10 September 2033 at 01:49 in ♈ Aries the lunar orbit is getting widen while the Moon is moving away from the Earth. It will keep this direction over the next 13 days until the Moon reaches the point of next apogee on 25 September 2033 at 01:33 in ♎ Libra.

Distance to Moon 363 491 km

The Moon is 363 491 km (225 863 mi) away from Earth and getting further over the next 13 days until the point apogee when Earth-Moon distance is going to be 406 444 km (252 553 mi).

Moon after descending node

1 day after descending node on 10 September 2033 at 19:07 in ♈ Aries the Moon is positioned south of the ecliptic over the following 13 days until the lunar crosses the ecliptic again from South to North in ascending node on 24 September 2033 at 12:46 in ♎ Libra.

Moon before northern standstill

8 days since the last southern standstill on 3 September 2033 at 09:54 in ♐ Sagittarius when the Moon has reached South declination of ∠-18.364° the lunar orbit is extending northward over the next 4 days to face maximum declination of ∠18.313° at the point of next northern standstill on 15 September 2033 at 23:39 in ♊ Gemini.

Draconic month

14 days since the beginning of this draconic month in ♎ Libra the Moon is navigating from the second to the final part of the lunar cycle.

Syzygy in 12 days

In 12 days on 23 September 2033 at 13:40 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.
