Waning Gibbous in Cancer

Waning Gibbous on . Illuminated surface of the Moon is 87% 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 ♋ Cancer

Moon is passing about ∠13° of ♋ Cancer tropical zodiac sector.

3 days after Full Moon

Previous main lunar phase is the Full Moon before 3 days on 18 November 2040 at 19:06.

Beaver Moon before 3 days

Next Full Moon is the Cold Moon of December 2040 after 26 days on 18 December 2040 at 12:16.

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 ∠1777"

Lunar disc appears visually 9% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1777" and ∠1943".

Lunation 505 / 1458

The Moon is 18 days old and navigating from the middle to the last part of the current synodic month. This is lunation 505 of Meeus index or 1458 from Brown series.

Synodic month length 29.53 days

The length of this lunation is 29 days, 12 hours and 37 minutes and it is 1 hour and 2 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 7 minutes shorter than the mean synodic month length. It is 6 hours and 2 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit details for

True anomaly ∠297°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠297° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠323.5°.

Moon before apogee

13 days since point of perigee on 9 November 2040 at 06:17 in ♑ Capricorn 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 24 November 2040 at 19:12 in ♌ Leo.

Distance to Moon 403 428 km

The Moon is 403 428 km (250 679 mi) away from Earth and getting further over the next 2 days until the point apogee when Earth-Moon distance is going to be 404 851 km (251 563 mi).

Moon after ascending node

3 days after ascending node on 18 November 2040 at 14:37 in ♉ Taurus 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 3 December 2040 at 01:02 in ♏ Scorpio.

Moon at northern standstill

At 02:56 the Moon is meeting its standstill point to reach North declination of ∠26.813°. This is the year's northernmost lunar standstill of 2040. Over the upcoming 13 days the lunar orbit is going to tilt southward to face maximum declination of ∠-26.791° at the point of next southern standstill in ♑ Capricorn on 6 December 2040 at 01:37.

Draconic month

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

Syzygy in 11 days

In 11 days on 4 December 2040 at 07:33 in ♐ Sagittarius 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.
