Waning Gibbous in Gemini

Waning Gibbous on . The illuminated surface of the moon is 99% and getting smaller. The lunar cycle is 15 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 is entering ♊ Gemini

Moon is passing first ∠0° of ♊ Gemini tropical zodiac sector.

1 day after Full Moon

Previous main lunar phase is the Full Moon before 1 day on 8 December 2079 at 15:16.

Cold Moon before 1 day

Next Full Moon is the Wolf Moon of January 2080 after 28 days on 7 January 2080 at 01:45.

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 ∠1972"

Lunar disc appears visually 1.2% wider than solar disc. Moon and Sun apparent angular diameters are ∠1972" and ∠1948".

Lunation 988 / 1941

The Moon is 15 days old and navigating from the middle to the last part of the current synodic month. This is lunation 988 of Meeus index or 1941 from Brown series.

Synodic month length 29.79 days

The length of this lunation is 29 days, 19 hours and 2 minutes and it is 22 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 6 hours and 18 minutes longer than the mean synodic month length. It is 45 minutes shorter compared to 21st century's longest synodic month length.

Lunar orbit details for

True anomaly ∠148.4°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠148.4° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠174.6°.

Moon at perigee

Moon is at perigee at 06:48 about 12 days since last apogee on 26 November 2079 at 15:51 in ♑ Capricorn the lunar orbit is going to widen while the Moon is moving away from the Earth over the upcoming 14 days until point of next apogee on 23 December 2079 at 21:45 in ♑ Capricorn.

Distance to Moon 357 291 km

This perigee Moon is 357 291 km (222 010 mi) away from Earth. It is 5 217 km closer than the mean perigee distance, but it is still 13 065 km further than the closest perigee of 21st century.

Moon after ascending node

4 days after ascending node on 4 December 2079 at 19:50 in ♈ Aries the Moon is positioned north of the ecliptic over the following 7 days until the lunar crosses the ecliptic again from North to South in descending node on 17 December 2079 at 08:14 in ♎ Libra.

Moon at northern standstill

At 17:56 the Moon is meeting its standstill point to reach North declination of ∠28.228°. Over the upcoming 13 days the lunar orbit is going to tilt southward to face maximum declination of ∠-28.189° at the point of next southern standstill in ♑ Capricorn on 23 December 2079 at 10:12.

Draconic month

4 days since the beginning of this draconic month in ♈ Aries the Moon is navigating from the beginning to the first part of the lunar cycle.

Syzygy in 13 days

In 13 days on 23 December 2079 at 06:31 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.
