Waning Gibbous in Gemini

Waning Gibbous on . The illuminated surface of the moon is 87% and getting smaller. The lunar cycle is 18 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.

Upcoming main moon phases

Main moon phases of the following lunar cycle.

Moon phase and lunation details

Moon is entering ♊ Gemini

Moon is passing first ∠1° of ♊ Gemini tropical zodiac sector.

3 days after Full Moon

Previous main lunar phase is the Full Moon before 3 days on 8 October 2033 at 10:58.

Hunter Moon before 3 days

Next Full Moon is the Beaver Moon of November 2033 after 26 days on 6 November 2033 at 20:32.

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 ∠1945"

Lunar disc appears visually 1.2% wider than solar disc. Moon and Sun apparent angular diameters are ∠1945" and ∠1923".

Lunation 417 / 1370

The Moon is 18 days old and navigating from the middle to the last part of the current synodic month. This is lunation 417 of Meeus index or 1370 from Brown series.

Synodic month length 29.74 days

The length of this lunation is 29 days, 17 hours and 49 minutes and it is 22 minutes shorter 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 longer than mean

The length of the current synodic month is 5 hours and 5 minutes longer than the mean synodic month length. It is 1 hour and 58 minutes shorter compared to 21st century's longest synodic month length.

Lunar orbit details for

True anomaly ∠166.6°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠166.6° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠190.3°.

Moon after perigee

2 days since point of perigee on 8 October 2033 at 12:11 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 10 days until the Moon reaches the point of next apogee on 22 October 2033 at 03:15 in ♎ Libra.

Distance to Moon 368 458 km

The Moon is 368 458 km (228 949 mi) away from Earth and getting further over the next 10 days until the point apogee when Earth-Moon distance is going to be 406 439 km (252 549 mi).

Moon after descending node

3 days after descending node on 8 October 2033 at 05:55 in ♈ Aries the Moon is positioned south of the ecliptic over the following 10 days until the lunar crosses the ecliptic again from South to North in ascending node on 21 October 2033 at 19:04 in ♎ Libra.

Moon before northern standstill

10 days since the last southern standstill on 30 September 2033 at 17:33 in ♐ Sagittarius when the Moon has reached South declination of ∠-18.282° the lunar orbit is extending northward over the next day to face maximum declination of ∠18.284° at the point of next northern standstill on 13 October 2033 at 07:00 in ♊ Gemini.

Draconic month

16 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 11 days

In 11 days on 23 October 2033 at 07:28 in ♏ Scorpio 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.
