Waning Gibbous in Cancer

Waning Gibbous on . Illuminated surface of the Moon is 93% and getting smaller. Lunar cycle is 17 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 ∠12° of ♋ Cancer tropical zodiac sector.

2 days after Full Moon

Previous main lunar phase is the Full Moon before 2 days on 2 December 2009 at 07:30.

Cold Moon before 2 days

Next Full Moon is the Cold Moon of December 2009 after 27 days on 31 December 2009 at 19:13.

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 ∠1963"

Lunar disc appears visually 0.8% wider than solar disc. Moon and Sun apparent angular diameters are ∠1963" and ∠1947".

Lunation 122 / 1075

The Moon is 17 days old and navigating from the middle to the last part of the current synodic month. This is lunation 122 of Meeus index or 1075 from Brown series.

Synodic month length 29.7 days

The length of this lunation is 29 days, 16 hours and 48 minutes and it is 2 hours and 21 minutes shorter than the upcoming lunation's length. The lengths of the following synodic months are going to increase with the lunar orbit true anomaly getting closer to the value it has at the point of New Moon at apogee (∠180°).

Lunation length longer than mean

The length of the current synodic month is 4 hours and 4 minutes longer than the mean synodic month length. It is 2 hours and 59 minutes shorter compared to 21st century's longest synodic month length.

Lunar orbit details for

True anomaly ∠99.9°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠99.9° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠135.6°.

Moon at perigee

Moon is at perigee at 14:12 about 11 days since last apogee on 22 November 2009 at 20:07 in ♒ Aquarius the lunar orbit is going to widen while the Moon is moving away from the Earth over the upcoming 16 days until point of next apogee on 20 December 2009 at 14:54 in ♒ Aquarius.

Distance to Moon 363 479 km

This perigee Moon is 363 479 km (225 855 mi) away from Earth. It is 971 km closer than the mean perigee distance, but it is still 6 877 km further than the closest perigee of 21st century.

Moon before descending node

13 days after ascending node on 21 November 2009 at 11:34 in ♑ Capricorn the Moon is positioned north of the ecliptic over the following day until the lunar crosses the ecliptic again from North to South in descending node on 5 December 2009 at 03:18 in ♋ Cancer.

Moon after northern standstill

1 day since the last northern standstill on 2 December 2009 at 23:37 in ♊ Gemini when the Moon has reached North declination of ∠25.772° the lunar orbit is extending southward over the next 11 days to face maximum declination of ∠-25.769° at the point of next southern standstill on 16 December 2009 at 02:38 in ♐ Sagittarius.

Draconic month

13 days since the beginning of this draconic month in ♑ Capricorn the Moon is navigating from the beginning to the first part of the lunar cycle.

Syzygy in 12 days

In 12 days on 16 December 2009 at 12:02 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.
