Waning Gibbous in Cancer

Waning Gibbous on . Illuminated surface of the Moon is 69% and getting smaller. Lunar cycle is 20 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 is entering ♋ Cancer

Moon is passing first ∠0° of ♋ Cancer tropical zodiac sector.

6 days after Full Moon

Previous main lunar phase is the Full Moon before 6 days on 10 October 2003 at 07:27.

Hunter Moon before 6 days

Next Full Moon is the Beaver Moon of November 2003 after 23 days on 9 November 2003 at 01:14.

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 ∠1784"

Lunar disc appears visually 7.6% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1784" and ∠1925".

Lunation 46 / 999

The Moon is 20 days old and navigating from the middle to the last part of the current synodic month. This is lunation 46 of Meeus index or 999 from Brown series.

Synodic month length 29.4 days

The length of this lunation is 29 days, 9 hours and 41 minutes and it is 28 minutes shorter than the upcoming lunation's length. This is the year's shortest synodic month of 2003. 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 3 hours and 3 minutes shorter than the mean synodic month length. It is 3 hours and 6 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit details for

True anomaly ∠325.5°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠325.5° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠344°.

Moon after apogee

2 days since point of apogee on 14 October 2003 at 02:27 in ♊ Gemini the lunar orbit is getting narrow while the Moon is moving towards the Earth. It will keep this direction over the next 9 days until the Moon reaches the point of next perigee on 26 October 2003 at 11:34 in ♏ Scorpio.

Distance to Moon 401 846 km

The Moon is 401 846 km (249 696 mi) away from Earth and getting closer over the next 9 days until the point perigee when Earth-Moon distance is going to be 358 549 km (222 792 mi).

Moon after ascending node

3 days after ascending node on 13 October 2003 at 03:40 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 26 October 2003 at 18:43 in ♏ Scorpio.

Moon before northern standstill

13 days since the last southern standstill on 2 October 2003 at 17:06 in ♑ Capricorn when the Moon has reached South declination of ∠-26.963° the lunar orbit is extending northward over the next day to face maximum declination of ∠27.054° at the point of next northern standstill on 17 October 2003 at 03:41 in ♋ Cancer.

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 9 days

In 9 days on 25 October 2003 at 12:50 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.
