Waxing Gibbous in Gemini

Waxing Gibbous on . Illuminated surface of the Moon is 96% and growing larger. Lunar cycle is 13 days young.

Moonrise and moonset

Moon rises in the afternoon and sets after midnight to early morning. It is visible to the southeast in early evening and it is up for most of the night.

Upcoming main moon phases

Main moon phases of the following lunar cycle.

Moon phase and lunation details

Moon is entering ♊ Gemini

Moon is passing first ∠2° of ♊ Gemini tropical zodiac sector.

5 days after First Quarter

Previous main lunar phase is the First Quarter before 5 days on 10 December 2040 at 23:30.

Cold Moon after 2 days

Next Full Moon is the Cold Moon of December 2040 after 2 days on 18 December 2040 at 12:16.

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 ∠1830"

Lunar disc appears visually 6.3% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1830" and ∠1950".

Lunation 506 / 1459

The Moon is 13 days young and navigating from the first to the middle part of the current synodic month. This is lunation 506 of Meeus index or 1459 from Brown series.

Synodic month length 29.48 days

The length of this lunation is 29 days, 11 hours and 35 minutes and it is 1 hour 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 shorter than mean

The length of the current synodic month is 1 hour and 9 minutes shorter than the mean synodic month length. It is 5 hours longer compared to 21st century's shortest synodic month length.

Lunar orbit details for

True anomaly ∠323.5°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠323.5° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠342.7°.

Moon before apogee

9 days since point of perigee on 6 December 2040 at 13:20 in ♑ Capricorn the lunar orbit is getting widen while the Moon is moving away from the Earth. It will keep this direction over the next 6 days until the Moon reaches the point of next apogee on 22 December 2040 at 13:29 in ♌ Leo.

Distance to Moon 391 662 km

The Moon is 391 662 km (243 367 mi) away from Earth and getting further over the next 6 days until the point apogee when Earth-Moon distance is going to be 405 778 km (252 139 mi).

Moon after ascending node

1 day after ascending node on 15 December 2040 at 21:13 in ♉ Taurus the Moon is positioned north of the ecliptic over the following 13 days until the lunar crosses the ecliptic again from North to South in descending node on 30 December 2040 at 10:13 in ♏ Scorpio.

Moon before northern standstill

10 days since the last southern standstill on 6 December 2040 at 01:37 in ♑ Capricorn when the Moon has reached South declination of ∠-26.791° the lunar orbit is extending northward over the next 2 days to face maximum declination of ∠26.761° at the point of next northern standstill on 19 December 2040 at 10:11 in ♋ Cancer.

Draconic month

1 day 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 2 days

In 2 days on 18 December 2040 at 12:16 in ♊ Gemini the Moon is going to be in a Full Moon geocentric opposition with the Sun and thus forming the next Sun-Earth-Moon syzygy alignment.
