Waning Gibbous in Gemini

Waning Gibbous on . Illuminated surface of the Moon is 89% and getting smaller. Lunar cycle is 18 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 ♊ Gemini

Moon is passing about ∠17° of ♊ Gemini tropical zodiac sector.

3 days after Full Moon

Previous main lunar phase is the Full Moon before 3 days on 28 October 2004 at 03:07.

Hunter Moon before 3 days

Next Full Moon is the Beaver Moon of November 2004 after 26 days on 26 November 2004 at 20:07.

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 ∠1776"

Lunar disc appears visually 8.5% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1776" and ∠1933".

Lunation 59 / 1012

The Moon is 18 days old and navigating from the middle to the last part of the current synodic month. This is lunation 59 of Meeus index or 1012 from Brown series.

Synodic month length 29.49 days

The length of this lunation is 29 days, 11 hours and 39 minutes and it is 37 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 1 hour and 5 minutes shorter than the mean synodic month length. It is 5 hours and 4 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit details for

True anomaly ∠302.8°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠302.8° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠327.5°.

Moon before apogee

13 days since point of perigee on 18 October 2004 at 00:03 in ♐ Sagittarius the lunar orbit is getting widen while the Moon is moving away from the Earth. It will keep this direction over the next 2 days until the Moon reaches the point of next apogee on 2 November 2004 at 18:09 in ♋ Cancer.

Distance to Moon 403 588 km

The Moon is 403 588 km (250 778 mi) away from Earth and getting further over the next 2 days until the point apogee when Earth-Moon distance is going to be 404 999 km (251 655 mi).

Moon after ascending node

3 days after ascending node on 27 October 2004 at 21:41 in ♈ Aries the Moon is positioned north of the ecliptic over the following 10 days until the lunar crosses the ecliptic again from North to South in descending node on 11 November 2004 at 07:43 in ♏ Scorpio.

Moon before northern standstill

12 days since the last southern standstill on 19 October 2004 at 08:00 in ♑ Capricorn when the Moon has reached South declination of ∠-28.048° the lunar orbit is extending northward over the next day to face maximum declination of ∠28.042° at the point of next northern standstill on 2 November 2004 at 01:32 in ♋ Cancer.

Draconic month

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

Syzygy in 12 days

In 12 days on 12 November 2004 at 14:27 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.
