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 in ♊ Gemini

Moon is passing about ∠15° of ♊ Gemini tropical zodiac sector.

6 days after First Quarter

Previous main lunar phase is the First Quarter before 6 days on 22 December 2039 at 10:01.

Cold Moon after 2 days

Next Full Moon is the Cold Moon of December 2039 after 2 days on 30 December 2039 at 12:37.

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 ∠1771"

Lunar disc appears visually 9.7% narrower than solar disc. Moon and Sun apparent angular diameters are ∠1771" and ∠1951".

Lunation 494 / 1447

The Moon is 13 days young and navigating from the first to the middle part of the current synodic month. This is lunation 494 of Meeus index or 1447 from Brown series.

Synodic month length 29.45 days

The length of this lunation is 29 days, 10 hours and 53 minutes and it is 6 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 shorter than mean

The length of the current synodic month is 1 hour and 51 minutes shorter than the mean synodic month length. It is 4 hours and 18 minutes longer compared to 21st century's shortest synodic month length.

Lunar orbit details for

True anomaly ∠356.9°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠356.9° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠12.4°.

Moon before apogee

12 days since point of perigee on 15 December 2039 at 20:51 in ♐ Sagittarius 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 29 December 2039 at 16:34 in ♊ Gemini.

Distance to Moon 404 680 km

The Moon is 404 680 km (251 456 mi) away from Earth and getting further over the next day until the point apogee when Earth-Moon distance is going to be 406 355 km (252 497 mi).

Moon in ascending node

Moon is in ascending node in ♊ Gemini at 08:24 crossing the ecliptic from South to North. Lunar position remains north of if for the upcoming 13 days until Moon's next descending node later on 11 January 2040 at 10:06 in ♐ Sagittarius.

Moon before northern standstill

11 days since the last southern standstill on 16 December 2039 at 19:27 in ♑ Capricorn when the Moon has reached South declination of ∠-25.464° the lunar orbit is extending northward over the next 2 days to face maximum declination of ∠25.448° at the point of next northern standstill on 30 December 2039 at 16:29 in ♋ Cancer.

New draconic month

At 08:24 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 2 days

In 2 days on 30 December 2039 at 12:37 in ♋ Cancer 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.
