Waxing Gibbous in Gemini

Waxing Gibbous on . Illuminated surface of the Moon is 95% and growing larger. Lunar cycle is 12 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 ∠6° of ♊ Gemini tropical zodiac sector.

4 days after First Quarter

Previous main lunar phase is the First Quarter before 4 days on 18 December 2015 at 15:14.

Cold Moon after 1 day

Next Full Moon is the Cold Moon of December 2015 after 1 day on 25 December 2015 at 11:11.

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 ∠1951".

Lunation 197 / 1150

The Moon is 12 days young and navigating from the first to the middle part of the current synodic month. This is lunation 197 of Meeus index or 1150 from Brown series.

Synodic month length 29.63 days

The length of this lunation is 29 days, 15 hours and 1 minute and it is 1 hour and 53 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 2 hours and 17 minutes longer than the mean synodic month length. It is 4 hours and 46 minutes shorter compared to 21st century's longest synodic month length.

Lunar orbit details for

True anomaly ∠255.6°

The true anomaly of the Moon orbit at the beginning of this lunation cycle is ∠255.6° and at the beginning of the next lunar synodic month the true anomaly is going to be ∠292.2°.

Moon after perigee

2 days since point of perigee on 21 December 2015 at 08:53 in ♉ Taurus 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 2 January 2016 at 11:53 in ♎ Libra.

Distance to Moon 370 918 km

The Moon is 370 918 km (230 478 mi) away from Earth and getting further over the next 9 days until the point apogee when Earth-Moon distance is going to be 404 279 km (251 207 mi).

Moon after descending node

4 days after descending node on 18 December 2015 at 15:13 in ♓ Pisces the Moon is positioned south of the ecliptic over the following 8 days until the lunar crosses the ecliptic again from South to North in ascending node on 31 December 2015 at 20:19 in ♍ Virgo.

Moon before northern standstill

11 days since the last southern standstill on 12 December 2015 at 08:15 in ♑ Capricorn when the Moon has reached South declination of ∠-18.438° the lunar orbit is extending northward over the next day to face maximum declination of ∠18.444° at the point of next northern standstill on 25 December 2015 at 07:30 in ♋ Cancer.

Draconic month

18 days since the beginning of this draconic month in ♍ Virgo the Moon is navigating from the second to the final part of the lunar cycle.

Syzygy in 1 day

In 1 day on 25 December 2015 at 11:11 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.
