Waning Gibbous in Cancer

Waning Gibbous on . Illuminated surface of the Moon is 83% 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 ∠9° of ♋ Cancer tropical zodiac sector.

4 days after Full Moon

Previous main lunar phase is the Full Moon before 4 days on 9 November 2003 at 01:14.

Beaver Moon before 4 days

Next Full Moon is the Cold Moon of December 2003 after 25 days on 8 December 2003 at 20:37.

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 ∠1789"

Lunar disc appears visually 8% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1789" and ∠1939".

Lunation 47 / 1000

The Moon is 18 days old and navigating from the middle to the last part of the current synodic month. This is lunation 47 of Meeus index or 1000 from Brown series.

Synodic month length 29.42 days

The length of this lunation is 29 days, 10 hours and 9 minutes and it is 35 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 shorter than mean

The length of the current synodic month is 2 hours and 35 minutes shorter than the mean synodic month length. It is 3 hours and 34 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit details for

True anomaly ∠344°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠344° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠359.8°.

Moon after apogee

2 days since point of apogee on 10 November 2003 at 12:05 in ♊ Gemini the lunar orbit is getting narrow while the Moon is moving towards the Earth. It will keep this direction over the next 10 days until the Moon reaches the point of next perigee on 23 November 2003 at 23:14 in ♏ Scorpio.

Distance to Moon 400 617 km

The Moon is 400 617 km (248 932 mi) away from Earth and getting closer over the next 10 days until the point perigee when Earth-Moon distance is going to be 356 812 km (221 713 mi).

Moon after ascending node

4 days after ascending node on 9 November 2003 at 09:48 in ♉ Taurus the Moon is positioned north of the ecliptic over the following 9 days until the lunar crosses the ecliptic again from North to South in descending node on 23 November 2003 at 06:02 in ♏ Scorpio.

Moon at northern standstill

At 10:16 the Moon is meeting its standstill point to reach North declination of ∠27.105°. This is the year's northernmost lunar standstill of 2003. Over the upcoming 12 days the lunar orbit is going to tilt southward to face maximum declination of ∠-27.092° at the point of next southern standstill in ♑ Capricorn on 26 November 2003 at 09:16.

Draconic month

4 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 10 days

In 10 days on 23 November 2003 at 22:59 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.
