Waxing Gibbous in Gemini

Waxing Gibbous on . Illuminated surface of the Moon is 80% and growing larger. Lunar cycle is 10 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 in ♊ Gemini

Moon is passing about ∠12° of ♊ Gemini tropical zodiac sector.

3 days after First Quarter

Previous main lunar phase is the First Quarter before 3 days on 21 January 2040 at 02:21.

Wolf Moon after 4 days

Next Full Moon is the Wolf Moon of January 2040 after 4 days on 29 January 2040 at 07:54.

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 ∠1775"

Lunar disc appears visually 9.4% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1775" and ∠1949".

Lunation 495 / 1448

The Moon is 10 days young and navigating from the first to the middle part of the current synodic month. This is lunation 495 of Meeus index or 1448 from Brown series.

Synodic month length 29.46 days

The length of this lunation is 29 days, 10 hours and 59 minutes and it is 23 minutes shorter than the upcoming lunation's length. This is the year's shortest synodic month of 2040. 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 shorter than mean

The length of the current synodic month is 1 hour and 45 minutes shorter than the mean synodic month length. It is 4 hours and 24 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit details for

True anomaly ∠12.4°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠12.4° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠30.1°.

Moon before apogee

11 days since point of perigee on 13 January 2040 at 10:03 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 day until the Moon reaches the point of next apogee on 25 January 2040 at 22:42 in ♊ Gemini.

Distance to Moon 403 890 km

The Moon is 403 890 km (250 966 mi) away from Earth and getting further over the next day until the point apogee when Earth-Moon distance is going to be 405 896 km (252 212 mi).

Moon in ascending node

Moon is in ascending node in ♊ Gemini at 12:28 crossing the ecliptic from South to North. Lunar position remains north of if for the upcoming 14 days until Moon's next descending node later on 7 February 2040 at 15:18 in ♐ Sagittarius.

Moon before northern standstill

11 days since the last southern standstill on 13 January 2040 at 06:43 in ♑ Capricorn when the Moon has reached South declination of ∠-25.460° the lunar orbit is extending northward over the next 2 days to face maximum declination of ∠25.480° at the point of next northern standstill on 26 January 2040 at 22:14 in ♋ Cancer.

New draconic month

At 12:28 in the point ot ascending node the Moon is completing the last draconic month and is entering a new one while the lunar orbit is crossing the ecliptic from South to North.

Syzygy in 4 days

In 4 days on 29 January 2040 at 07:54 in ♌ Leo 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.
