Waning Gibbous in Cancer

Waning Gibbous on . The illuminated surface of the moon is 97% and getting smaller. The lunar cycle is 16 days old.

Moonrise and moonset

The 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.

Moon phase and lunation details

Moon in ♋ Cancer

Moon is passing about ∠20° of ♋ Cancer tropical zodiac sector.

1 day after Full Moon

Previous main lunar phase is the Full Moon before 1 day on 18 December 2078 at 23:34.

Cold Moon before 1 day

Next Full Moon is the Wolf Moon of January 2079 after 27 days on 17 January 2079 at 11:06.

Moderate tide

There is medium ocean tide on this date. Sun and Moon gravitational forces are not aligned, but meet at very acute angle, so their combined tidal force is moderate.

Apparent angular diameter ∠1932"

Lunar disc appears visually 0.9% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1932" and ∠1950".

Lunation 976 / 1929

The Moon is 16 days old and navigating from the middle to the last part of the current synodic month. This is lunation 976 of Meeus index or 1929 from Brown series.

Synodic month length 29.78 days

The length of this lunation is 29 days, 18 hours and 42 minutes and it is 1 hour and 57 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 longer than mean

The length of the current synodic month is 5 hours and 58 minutes longer than the mean synodic month length. It is 1 hour and 5 minutes shorter compared to 21st century's longest synodic month length.

Lunar orbit details for

True anomaly ∠196.6°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠196.6° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠225.6°.

Moon after perigee

2 days since point of perigee on 17 December 2078 at 21:10 in ♊ Gemini the lunar orbit is getting widen while the Moon is moving away from the Earth. It will keep this direction over the next 9 days until the Moon reaches the point of next apogee on 30 December 2078 at 02:17 in ♏ Scorpio.

Distance to Moon 370 985 km

The Moon is 370 985 km (230 519 mi) away from Earth and getting further over the next 9 days until the point apogee when Earth-Moon distance is going to be 405 665 km (252 069 mi).

Moon after ascending node

4 days after ascending node on 15 December 2078 at 19:09 in ♉ Taurus the Moon is positioned north of the ecliptic over the following 8 days until the lunar crosses the ecliptic again from North to South in descending node on 28 December 2078 at 21:50 in ♏ Scorpio.

Moon after northern standstill

1 day since the last northern standstill on 19 December 2078 at 14:06 in ♊ Gemini when the Moon has reached North declination of ∠27.536° the lunar orbit is extending southward over the next 13 days to face maximum declination of ∠-27.521° at the point of next southern standstill on 2 January 2079 at 17:40 in ♑ Capricorn.

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 13 days

In 13 days on 3 January 2079 at 06:50 in ♑ Capricorn 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.
